Title: PIAUDIO DIGIBUSS
Post by: rollo on December 21, 2015, 12:20:44 PM
   The latest from Guru Dave of PIAudio. Where has this been all my life. So natural ans analog sounding my CDP plugged into this.
    Yes I sell them and proud to do so. Retail is $350 ea. Another no-brainer from PIAudio.

I've got a DigiBuss and had a bit of an epiphany with it...

I started it out plugged between wall and UberBuss on my big rig.  I think it relaxed things a bit, but to be honest, the Uber was already doing a very nice job.

I remember Dave saying that a lot of noise on the line is due to computers and all those SMPS wall warts and the like.   So I moved the DigiBuss to my computer room (opposite side of the house) and centralized as much of my digital toys there along with running my computer, hard drives, and what not through it.

I thought it made a noticeable improvement in listening to computer audio (PC -> USB -> ifi Micro -> either headphones or Audioengine A2s.   So I just left it there and contemplated whether I should ask Santa for another one to put back in the big rig.     

That was a couple weeks ago.  Here's where it gets interesting... I realized I'd been having a string of "great sound" nights listening to the big rig and wondered if the DigiBuss on the computer where my music was being streamed could be playing a role in that.  So, like any good audiogeek, I pulled the DigiBuss out over the weekend.  Damned if the big rig didn't sound worse last night.  Now, sure, that is what I was anticipating and I did have a couple glasses of scotch (which normally helps the SQ but not last night).

I need to play with it more to see if I can isolate what's going on.  Of course, the digital thingees in my house are multiplying at an alarming rate and my fear is that I may need another 3 or 4 Digibusses to keep up.

I guess this is just for digital components ? Can you use this for the rest of the system? I see on A/C guys are plugging this into the Uber Buss.

  Yes recommended for digital only. What my customers tell me is they are getting more weight and jump factor plugging directly into an Uberbuss. A presence that just was not there before.
     PIAudio conditioners take serious time to break-in. at first the Digibuss will sound dull or warm. After a 24Hr burn -in a bit better. Full break-in occurs about 300 hours. Further improvements can be had with optional Furutech GTX series of duplex receptacles. The GTX-D Rhodium has exceptional tone and bass. The standard Pass & Seymor receptacles are just fine so not imperative to upgrade other than synergy. The Furutechs change tone a bit and may or may not fit your system.
    My personal Digibuss will have one Furutech, one Pass & Seymor and one yet to be named most likely a Voodoo Audio all copper.
    This way I can compare directly to better inform my customers.

    ...

Charles, I'm not clear on where you're customers are placing the DigiBuss... between wall and Uber or between Uber and digital components?

My experience with it between wall and Uber was just a slight improvement - a more relaxed presentation.  But admittedly, that's where I put it first and perhaps didn't give it enough time to burn in there.

First things first:  Merry Christmas and/or Happy Holidays everyone! We are in Portland OR with our daughters and families, presents are opened, pumpkin bread is eaten and oldest daughter Heather has the prime rib in the oven.  Life is good!

On to the DigiBUSS.

The Digi was designed as a bi-directional digital noise filter to KILL the digital nasties that are the rule not the exception these days.  iPhones, computers, power meter telemetry, kitchen appliances... everything has a chip or 9 insides anymore.  That is a bummer for most people.  It is also designed to be a better impedance match with SMPS than either wall supply or any of my BUSSes.  This is extremely important in the context of SQ.  This is particularly noticeable in soundstage dimensionality and timbre of acoustic instruments and the human voice (sibilance).

There are a couple of recommended ways to use a Digi.

I originally designed it to power all of the SMPS in my office/lab.  Even located at the opposite end of the house on the opposite branch circuit, I could hear the difference in SQ when all of the SMPS were on or off.  Sucked.  The second prototype solved the problem. 

Secondarily, it can be used as a standalone filter for a small system.  There is no PFC and it does contain an inductor, but the indicator is rated at 25A and the series resistance is < .001 ohm.

The primary audio function is to prevent digital hash from screwing with power supplies in a local system.  It will prevent RFI from polluting the PS of a digital source and/or DAC.  It will prevent the source and DAC from contaminating preamps, amps, crossovers... whatever.

Noise reduction begins at 120Hz.  100kHz is ~ -100dB down.  This frequency is where a majority of "digital filters" are at -3dB.  You can see why it is sooooooo quiet.  The 3 P&S 5362A Extra Hard Use Spec Grade are split into 2 outlets, each with its own filter for maximum noise reduction.  Choice of Furutech gold or rhodium plate inlets or a Neutrik powerCon input connector.  Standard finish is that adorable black textured finish that saves hundreds of $$$ in selling price.  Custom colors and enclosure materials are available.  Anything you can dream up I can do... you just need to be able to afford your dreams. :)

Additional and different receptacles are available, just inquire.

Mike C.,  for your system, plugging it into the Uber is definitely recommended.  Mike R.  No doubt that you are hearing the goodness of no hash.  What did you find out after you sobered up?   :rofl:  Then again, the best application is the one that sounds the best in YOUR system.  Please share your findings.  Inquiring minds want to know.

Let me know if ya'll have other questions.

Ho, ho, ho.............

   Well after one week of burn-in it is still changing. However the bass, and dynamics are so much better. The top end needs more time like the Uberbuss.
   The Furutech rhodium duplex has a more natural presentation out of the box compared to the P&S. However not enough time on hand to tell.
   So far a quieter background with explosive dynamics. No Hi Fi sound from digital anymore. It is gone, gone and gone.
    Kudos Dave it is a winner.

The DigiBUSS is going through a small change right now.  Nothing huge or mind blowing, just a production change to accommodate component availability.  It does not effect SQ, just allows me some attitude in component sourcing.  The difference is +/_ 5Hz in the LF turnover frequency.  I can't hear the difference, I'm just trying to allow for components being 12 weeks out.

Parts sourcing is one of the hardest things a small manufacturer like me needs to contend with in providing the best gear that I can.  I try to stay on top of availability issues.  I'm just glad I caught this one.

The Digi continues to amaze me and my customers.  RFI is running rampant in our systems these days.  I is more than curious that the elimination of it cleans up a system so much.  My greatest accolades are coming from people that have analog front ends.  Seems that the elimination of RFI in the head amp is extremely important.  Makes perfect sense tome.

I hope that those of you that have the Digis will post your results and also suggestions for making it better.  Same goes for all of my products.

At this point all I can say is: Go Denver!!!  I just want to see Peyton get that which has always eluded him...  He truly deserves it.

A few words on my experiences using the DigiBUSS.

I have the DigiBUSS circuit built into a customised MiniBUSS with a defeat switch, making comparisons very easy.

After giving the MiniBUSS several weeks burn-in period with the DigiBUSS circuit engaged, I disengaged it. Suddenly there was an added tizz, a flattening of the sound-stage and image depth, and an added quality to the music that made it seem less natural. All this was quite obvious, though not dramatic, never the less detracted from the listening enjoyment quite significantly, and I soon had to switch the circuit back in to resume my listening pleasure. I found what I heard quite surprising, as I was expecting something much more subtle, and all this after the MiniBUSS and two of the excellent LessLoss Firewall Modules, which together made a substantial improvement!

So, for the price of an inexpensive tweak, Dave offers a very worthwhile addition.

   Could not agree more. If one owns a digital anything the Digibuss is a no brainer. TV and cable box as well just stunning color.
    It is like buying a new DAC or CDP IMHO. Selling like hotcakes

Thank you for your observations on what the DigiBUSS concept does when used in your system.  I'm very pleased that you are pleased and appreciate the review.

Your use of the word "tizz" is one of the best terms I have heard in conjunction with digital noise.  That sense of graininess is a white noise component in the extreme highs.  It not only pollutes the power supply rails and ground plane in equipment, but uses more power than one would think in reproducing it.  It is hard on tweeters, too.

A little more info about Mr. Massarano's special unit. We talked for some time about what to build for his 250VAC application.  Ended up with a hybrid of a DigiMini(MiniDigi?)BUSS using Schuko receptacles.  We settled on the GigaWatt Schukos and I have to say that they are exceptional in build and sound quality.  Well worth the wait.  For any of you Nervous Guys that live where Schukos are the norm I highly recommend them.

Remember that the DB was designed to quell the SMPS digital nasties.

If you can, get all of the wall warts together in one location on the opposing branch circuit to your system. You will still get noise on the neutral, but you will have 'some' attenuation on the hot.

You are right about additional noise suppression for D-nasties, no matter what you use.

Noise just sucks.

Subtle ootzes are not lost on me.  Rollo and I are in cahoots to have some traveling demos of the Uber and DigiBUSS available for audition. There will need to be credit card surety and prepayment for shipment to the auditioner, but beyond that knock yourself out.  I'm going to try to get these to him before we leave for the Bonamassa Blues Alive at Sea cruise Feb 14 - 20.  No promises... I'm still having some supply issues, but have pieces/parts inbound.

While I agree that using balanced power can be the best way to go, I am not sure how practical it would be to build that intio a unit like a digibuss. For this to work you could not just feed the unit with any two 120v feeds, but rather you would need to have two separate feeds, one from the A buss and one from the B buss of your incoming service. Secondly, the two feeds would need to be very close to one another because if they were different lengths you could end up wit ground loop problems between the two feeds. The chances of that happening in a normal residential situation is pretty slim. What you would really need is a 240 outlet run to the room where the system is. And even then I am not sure it would be the best of ideas since 240 to 120 transformers then to vibrate mechanically produce an audible hum that most audiophiles would find objectionable in their listening room. For this reason balanced power transformers are almost always located right by the service panel and the balanced 120v is then run to the listening room via a dedicated circuit.

Now perhaps Dave could come up with a new balanced power unit that would combine his filtering magic with a 240/120 transformer in a form factor that would wall mount by your panel, but I am just not sure it would be practical add that functionality to the Digibuss as it sits now.

Gentlemen, 

Balanced power: been there done that will not go back for a home system.  Transformers can be a bigger PITA than most people are will to deal with.  They can be a great solution 'in some instances', but are not a cure all.  The biggest issue is current limiting.

When Philips Semiconductor closed here in 2002 there were a lot of Topaz Ultra Isolation transformers that went on the surplus market.  I bought a couple of the ultra low capacitance 2.5KVA T5's at that time for $75.00 each.  :shock: They are not balanced but offer noise suppression > 120dB.  My system at the time was comprised of Cary CAD572SE Mk.ii, an over the top modified sLP50-B preamp and a 306 CD player.  Even with the fairly constant current draw of the system the onlt time it did not sound compressed was with the transformer feeding an UberBUSS so the PFC network would provide the instantaneous current need during transients.  One one think that a 20A supply to class A amps would do the job on amps that drew a total of <450W.  Didn't.  It weighs 60 pounds and has a weighted noise component of 30dBA at 450Btu/hour.  Works great in the crawlspace under the house protecting the flatscreen and related gear.  Best surge protection going.

If you want black, velvety dynamics the UberBUSS was created to do that job. This MiniBUSS and DigiBUSS are built for specialized applications at low cost.  The Uber is all about heavy lifting in the SQ arena.  Charles will have a broken in Uber as well as DigiBUSS for traveling audition next week.  After all, I build all things in the power treatment arena, even a surge protector (BUSS-Stop)... even though I am a proponent of whole house panel mount surge protectors.  There's something for everyone.  If not I'll design/build.  All you have to have is time and money.

My Torus Rm20 is dead quiet.  It's a dual phase 120v 10amp service. It gives me a 120V 20 amp at the outlets. It's better for the front end than amps.... Lol

I can assure you this Torus does not hold back on transient current. I agree though, one might need at least a 20 amp service at the outlets. It's got to be overkill even for the front end. 15 amp service fed from a regular house mains maybe not for amps in current restrictions. I have heard Torus RM15s but not in my house so I am not sure.  But that's for amps, for front end it can be less but the dual phase just keeps it lit. It's the way to go where I am.

Dual phase for current is like what voltage regulation is for 120V.  The thing is in constant supply and never sees a saturated core.. It's a thing of sonic beauty. I think the reason why it's so quiet to is that there is a 120V 20 amp feed in with a 120V 20 amp feed out. I am not sure if the 30 or 60 amp services are noisy. Might be.

One thing I have learned through experience with power products and audio is that there are never seem to be any absolutes. I have had things that worked wonders in my house that I brought to a friends  and they sounded like crap and things that did basically nothing for me that made wondrous changes somewhere else. I am sure it all has to do with what exactly of no perfect about your power in your house vs somebody else's power situation. So if that transformer is working well for you, go with it and enjoy.

One thing I have learned through experience with power products and audio is that there are never seem to be any absolutes. I have had things that worked wonders in my house that I brought to a friends  and they sounded like crap and things that did basically nothing for me that made wondrous changes somewhere else. I am sure it all has to do with what exactly of no perfect about your power in your house vs somebody else's power situation. So if t4hat transformer is working well for you, go with it and enjoy.
Dude! I gurantee (and I mean 150% gaurantee) if you plugged your front end including preamp Into a 240v dual phase conditioner you would have a completely different perspective. Only because dual phase is meant for audio like a momma's booby is for her baby. The trick is to get the thing down to 120V service quietly using a transformer that doesn't hold back current.

I do not have my amps into the Torus. Well my Bryston I didn't and my Chapter doesn't work. My Chapter turns on but no music plays. Its a mystery. But my Bryston14Bsst2 sounded like it was too close to another huge transformer. My old 4Bsst/2 sounded lit. Totally charged and ready to go. My 140 watt Blue Circle spanked my 4B when I had into the Torus240 compared to the 4B in the wall. Both in the wall the Blue Circle could not keep up to the 4B.

My Chapter amp works but not through that conditioner. It only works plugged into the wall. That is what I meant to say. The thing turns on and functions to commands but no music...

One thing that I am absolutely sure of is there are no absolutes in audio.  Overtime I try to find an application that is universal I come up with 1 or 9 reasons that it isn't.

The bottom line (HA!) is that what works, works.  Sometimes there is no rhyme or reason of it to do so.  This just tells us that all of those things we learned in school may not necessarily be applicable to what we are doing.  We tend to view everything simplistically. 

Let's just take one example:  Power cables

I do not pretend to understand everything that I think I know about electricity.  I know what they taught me in school.  Ohm's law ruled everything when I was a youngster. PIE, baby  :thumb:  I=V/R .  Unfortunately, that is just the beginning of the topic.  It is a topic to which I have found no end.

I remember some years ago when I was debating the topic of power cables on a well respected DIY forum. I remember being belittled for A: even thinking that a power cable could possibly make an audible change in SQ (sound quality).  After all, convention wisdom (which I generally find to be neither) dictated that if you had enough power that was ALL you need -B; the diameter of my cables.  I could not make ANYONE there understand the concepts of: conductor purity, geometry, inductance, capacitance, dielectric absorption, dissipation factor, insulator Q, termination quality, transmission line theory, connectors and on and on and on and on and..........

In the words of a now passed theoretical physicist friend of mine that was a mentor (and a "gasp" Christian) that made me think of reasons, purposes and solutions to problems:  "we don't REALLY, on a quantum level understand how all of this (the universe) works".  we have to understand what we do not understand.  That is wisdom and the quest of thinking people.

The beauty of forums like this is that we can share and do joint research on stuff that DOES NOT WORK.  This kind of thing saves money and more importantly time.  I will be 68 on the 25th and I want to keep learning, sharing and developing products that meet the needs of most people.  I don't purport to be so arrogant as to say that I have the SUPER DUPER DOO-DAH that meets everyones need.

Damn, wish I did.

Rock on, guys what works, works.  Keep on chooglin'...

Some most valuable professional advise I ever got was from one of my professors in Engineering school.

He said the most important thing an engineer need to know is just what he does not know. And the most critical skill he needs to develop is the ability to admit that.

No seriously, there are absolutes in audio. One is running a 240v for an audio system. Or at least multiple 15 amp services. Its the same reason why you can not run a stove on 120V. The power to run out all elements and stove heat is not capable on  120V. Powering a system is about overkill. If you are going to run a conditioner it may as well be in 240V to accommodate that. Everything will work fed 120V but really should be in front of a transformer. There is a ratio though and the conditioner needs to dwarf the VA power ahead of it. Or else its gets gimped. Then i agree, since the local transformer will be overkill (if you are close enough to it). Then it might better running multiple 15 amp dedicated services.

I absolutely agree  :) that having adequate power is an absolute when it comes to great SQ.  I guess that make my "no absolutes" post absolutely wrong.

Absolutely.

Systems have to have adequate power to live AND breathe.  Without it there can't be the unrestrained dynamics (Micro and macro) that we demand from our systems.  This is why I suggest 4 - 20A circuits for best results.  Getting them all on the same branch circuit is hard, but they HAVE to live at the same ground potential and on the same "phase' (although that isn't necessarily what it seems.  To be effective one is for the front end, one for the amps, one for digital and one for subs.  If we had current and spaces in the panel to burn I could break it down farther.  Seeing how this is stretching it, even in new construction, I recommend one for analog and one for digital.  That way we can address the weirdnesses of each unto their own.

I remember when I got my first dedicated circuit back in the late '80s.  It was amazing! Life was somehow simpler then.  :)

I prefer one for amplification and one for source. You can have analogue or digital on the same line assuming one is turned off.

It makes me wonder if  every 15 amp circuit should have only a single transformer on it? Or at least one big one. This is why I think transformer based conditioners in 240V are good in front of source gear. I admit this is conjecture but I don't think current is readily availabe to multiple transformers,  even if they are rated way under 15 amp VA power on one line. I think it has to do with hertz and what the local transformer can deliver. Or what the local thinks is on that 15 amp circuit. It may only delivery current to what it sees as the highest VA transformer. This is why we have brown outs on circuits that should not happen. Like when when we turn something on and a lamp will dim in an area where the power is stiff.

If we put a huge 240v transformer it immediately plays boss and becomes the dominating tranformer on the circuit and the local one does not care what is behind it.

There is no reason whatsoever that you couldn't run an electric stove on 120v. The reason that the are built to run on 240v circuits is simply cost. A self cleaning electric range requires a minimum of a 40 A 240v circuit. This means you need to wire it to the breaker box with -8-3 Romex which costs $1.80 /Ft. If you were to run the stove on 120v power it would pull 80 amps which would require you to wire it with 2-3 Romex which costs $9.70 a ft and in addition to the added cost id much heavier and more difficult to run i the tight inside the wall type spaces use to route electric wire in residential buildings. And in addition to that if wiring within the stove would need to be bulked up to carry the amperage that would be pulled in a 120v operation and that would increase the cost of the stove as well. So a stove would run perfectly fine at 120v, it just save a whole lot of money to run it at 240.

That said In the case of audio there is an advantage to using balanced power (a 240 volt circuit stepped down to 120 rather than just one phase referenced to ground) The common mode noise rejection of the balanced feed is much greater than that of a split phase circuit, and and that is why it sounds better. Unlike the case of a stove that just wants a big push, there is a big advantage in audio in having less noise in the incoming A/C power, which is why we use devices like the Uberbuss. But it only stands to reason that the less noise we put into the conditioner to start the better results we can expect.

But of course nothing is ever free because when adding step down transformers we will then need to deal with issues such the heat and mechanical vibrations they generate and other electrical issues related to transformers like core saturation.  Not that any of them have to be a game stopper, but they just add another layer of complexities that need to be dealt with.

I absolutely agree about having separate circuits for power amps. (Especially big ones like the ARC VT-200  :D)

When you think about it this is just an extension of why we have separate pre and power amps, so that any big transient draws by the power amp section with not starve the pre amp of the power it needs to operate.

Of course you can run a stove on 120V. You can even put a neutral on it for all the clocks and lights you want. All you will be cooking is Kraft Dinner.  :rofl:. If you want even heat on all elements and stove you need the dual phase current.

All i mean the oven is probably on one 120V phase and the elements, timers and everything are on another.  Which is the only allowable way that i can think of on a 15 amp house circuit. I have never seen a wiring diagram for a stove.

They are just out of phase. There is no step down and why i think it is so quiet.

2 120volt phases with a ground and no neutral. IF you got the AVR 240 volt ,probably need a neutral.

err - step-down at 240V - 2 120V 10 amp feeds to 120 20 amp single phase...  :lol:

I am having trouble describing...  :duh  :rofl:

What i like about 240V and its the same whether its stove or hi fi conditioner is the lack of a neutral return. On 240V the return drives the opposite phase. Opposed to the neutral back to the fuse box. I am not so sure  power cables and receptacles are doing their best work on the supply into the amp but are improving the return back to the local transformer. The return  completes the circuit and basically tells the transformer whats on the line and what it needs on the supply. Does't it? The ability for the transformer to return or complete the circuit i think is harder to accomplish than the forward powered leg of the local neighborhood transformer. So you have the positive 120V leg returning down the negative leg which drives the negative phase back. Returns down the positive phase and sets up the drive for the powered positive  return back. The return is driven by the change in current characteristics of the transformer. Its small on the return but the 120v potential seen by both transformers allow it to work.
What do you think. Does that make sense?

I really do not know how accurate that is. ?  It seems to make sense though.

Of course you couldn't run it on a 15 amp 120 circuit. My point was that an electric stove usually runs on a 40 amp 240 V circuit. It could just as well run on 120v, but then you would need an 80 amp 120 circuit and the wiring for that would be crazy expensive.

I got home last evening and decided to try the NC400s into the DigiBUSS.  I can say right off that lasted for one CD.  I much preferred the mono blocks into the UberBUSS. The sound was more natural and flowing. Ahhh the music is back is how I felt. YMMV. My setup:

Furutech GTX-D G
TWL 7+
UberBUSS - analog front end, preamp, mono blocks
DigiBUSS - CD Transport, DAC, Blu-ray, cable box, TV
ALL PCs are TWL, Digital Americans on amps and digital front end, 10+ on preamp

There you have it: empiricism at work.

Some SMPS don't like the Uber, especially the wall wart cheapies.  It is only the well designed ones with larger input inductors that do.  The nCore products are extremely well done and work great with the Uber.

Dave,

I read the thread and have a few questions.

I see members plugging this into the Uber first and then plugging your digital equipment (dac, fans, laptop etc) into Digi. The rest of the equipment (amps, cd etc)  plugs into Uber as usual. Is this correct?  

Or can you plug this into your same wall outlet as the Uber? From my understanding of how it works, it would take all the digital/transformer noise from your equipment in your front end out and leave the supply clean for the Uber. I understand this would have to be done elsewhere in the house where there are a lot of equipment with transformers to get rid of that noise as well in the overall power supply.

I will be ordering one but am slightly confused as to what equipment goes where and in what order.

I be contacting you to order one shortly. :-P

Since the UberBUSS and DigiBUSS are on different sides of my listening room, they are not connected together. It makes the digital system quieter than the PS Audio Ultimate Outlet I was using before with all the SMPS attached. 

My UberBUSS has a MicroBUSS attached for more outlets to the system.  All linear supplies on this pair.

Jesse, the best way to use the Digi/Uber combo is the way that sounds best.  I know that sounds flippant, but it is because there are few absolutes in audio.  Inflow power systems used with very high sensitivity speakers, plugging the Digi into the wall and the Uber into the Digi "may" sound better in homes with lots of CFL's, LED lamps and fans on speed controls, etc.  You have to assess your own noise generation and use the Digi where it will do the most good.  If you have a high power system with amps that draw a lot of current you will probably have better results with plugging the Uber into the wall and the Digi into the Uber.

The DigiBUSS is the only product that I make that is potentially current limiting.  Part of the guts of the Digi is a very low resistance 25A inductor that under high surge currents can show impedance that the same straight 34" length of 12a wire would not.

Bottom line:  whatever works, but I would plug the Digi into the Uber under normal conditions.

I've had a Digi-Buss and Buss-Stop for a few months now. The former has one Pass & Seymour 5362, one Furutech GTX Rhodium and one Furu GTX Gold. The latter has one Pass & Seymour 5362, one Furutech GTX Gold and one Furu FPX Gold.

Into the Digi-Buss are my Mac Mini, external HD, Uptone Regen, AR-T Legato and DAC. The Digi-Buss, and my amp during lightning season, are plugged into the Buss-Stop.

The Buss-Stop, like the Mini-Buss I had previously, does an excellent job of passing through power without degrading the sound in any significant way. There is just a slight diminution of macro-dynamics - with my amp only - which requires attentive listening to hear.

Although I have a whole house surge protector, the additional protection from external surges (I live in the lightning capitol of the country) as well as the protection from internal surges (refrigerator, washing machine, etc.) - especially for my computer gear - makes the Buss-Stop well worth the expense to me.

The Digi-Buss, on the other hand, reduces the noise level, provides more resolution, and actually increases both macro and micro dynamics. Again, well worth it for me.

Charles,  one of my heavy revvies in audio is just how important to SQ the power supplies for turntables is, especially when dealing with SMPS.  Yours is a wall wart that is a champ at creating noise and pumping in back into the AC.

If you have a Digi and an Uber the correct configuration is plugging the Digi into the Uber, not the other way around, just like you have learned.

Enjoy!

I've been burning in the Digibuss for the past 2 months and I feel that it has finally settled in.

(https://image.ibb.co/jG6vUk/digibuss2.jpg)

I’ve been in this audio hobby since the mid 90’s and I used to have a cd-based system which (from memory) sounded much better at rendering vocals. After being forced to downsize, I now only have a computer/headphone system. But no matter what I did –a new headphone, a new amp, new USB cables, a new DAC- I never liked the sound coming from the computer system. There was always something wrong with the sound, whether it was the thin, bleached-out midrange, a lack of dimensionality, or a certain ‘digital harshness’ to the sound that made everything sound unnatural and cold.

Sure, I got minor upgrades in sound by changing out power cords, interconnects, and USB cables, but these were minor improvements. The biggest improvement was when I got a medical isolation transformer to power the system. Alas and alack, improved silence came at the expense of dynamics and a softening of the sound. Transients were slower and robbed the sound of ‘jump’ factor. This got me to thinking.

I’ve always been suspicious of the electricity feeding my gear and since it is a computer-based system and having read how digital nasties can pollute the sound, I’ve been looking for a solution to get better sound. Unfortunately for me, not having the budget to afford the higher priced power treatment  such as  (insert your favourite power conditioner brand) meant I could not get the best our of the system.

Months of research looking for a cost-effective solution thankfully led me to PI Audio. A short email conversation with Dave convinced me to pull the trigger on a Digibusss and I am glad I did.

I do not consider the Digibuss an accessory. Without it, I cannot enjoy listening to music through the computer.

It is like a component upgrade, similar to getting a better dac or headphone amp with the level of detail and sound improvement I now get.

Users of the PI Audio power products are familiar with these improvements. Among them:


My only regret is only finding out about Dave’s products now and not getting it sooner!  :duh

Wow!  What a great boost to my egotistical desire to provide great products at a (more than) fair price.

Great audio does not require a ton of $$$ to have a tremendously satisfying -
read that as musical and satisfying - system.

I've always been on a budget, more so as I get older. Snob appeal is one thing, but appreciation is another.  Our obsession is about the "music" after all.

Thank you for a wonderful review.  It is greatly appreciated and makes me smile  :thumb:

Like I say: great reproduction is not about the notes.  Notes are easy.  Even MP3 gets the notes mostly right.  It is about the little things that are reproduced and live in the space between the notes.  Intimacy be one... Performances that bring us to tears with beauty is the BIG one

As I'm now breaking in an Uber, your post very accurately reflects what I'm hearing. It's a great product. I'm breaking in the second outlet, the Furutech G right now. The first was the unpolished Pass and Seymour.
If I had to do over, this product would be one of the first to buy when getting an audio system together. In that regard, it would be an amazing device to analyze your amp, preamp, cables etc

Thanks, Nick.  I do my best to build the best, cost no object products that I can... because they are ugly.  I build ugly black boxes full of beauty that are meant to reside behind the rack.  I can and will build other styles with audio jewelry faceplates and cases, but that easily adds a kilobuck to the cost.  I choose to spend my customers' money on the inside of the box, not for a pretty face.  I love pretty faces. but sometimes they have nothing inside.

I built Nick's with 4 different receptacles so he could hear the differences in presentation.  These are:

Pass & Seymour 5362A

Hand Polished Pass & Seymour 5362A  + $10.00

Furutech FPX(Cu) standard + $70.00, not my hand polished version  (+ $20.00 for hand polish).  These are pig to get apart and reassemble but sound awesome when hand polished...
 
Furutech FPX(G) + $95.00

The best receptacle available to date is the Furutech GTX NCF ( +280.00 !!!) Expensive but OMG!

I'll be very interested in what Nick finds to be the best for his applications.

2 days to take the upper mid edge off.  One week to make real music.  400 hours to finally be "THERE!"  When it gets THERE it is truly special in an industry of "me, too."

They all sound different and I think Nick will find the "perfect" combination for his system among them.

And the adventure continues...  8)

Thanks for keeping us all up to date, Nick.  It is asmazing just how much polishing adds, or more accurately takes away from the presentation.  Polishing the base metal helps to eliminate most of the micro arcing that will occur between connector surfaces.  Having highly polished blades is a very good adjunct to the polished contact fingers in the receptacles, too.  simply polishing the blades on a Wattgate standard connector and ing that with the polished P&S was my first foray into receptacle and plug modification and really opened my eyes (ears?) about surface finish being critical.I was going to polishe the FPX(Cu) too, but that is a pain in the butt to do.  Getting them apart is one thing, but reassembling them is quite another.  I can't swage the retainer ears.  I just haven't made the proper tool for that.  I have to silver solder them back together.  Once doe, that receptacle is very interesting.  I'll send you one you can just swap out with a FinalFilter already installed if you want.  Just let me know.

It's coming along well, but I've added too many variables. Gary has wanted me to add his power cord from Uber to the wall. So I finally did and it sounds good. He'll be at my house this Wednesday, so I'll be leaving it in for now. Break in for all receptacles is done, but I would now like to go back and disconnect my dac and finalize my decision re which is best for the amp. Then I'll repeat the process with the dac. I like the P & S polished, great sound and bang for buck.
Any of these changes result in a different sound. I need to analyze the change and see if it contributes to my goal of tonality and harmonics (this was Charles description in a recent post).
Interesting that bending Gary's cord resulted in a sound change. He uses solid 8 gauge copper. I had read about that phenomenon and it's the first time I've really experienced it due to the increased resolution that I have. 
I'll be getting the Nola's soon, so that'll be another change. But it's all a fun process  :thumb:

  The Uber takes 300 to 400 hours IMO to stop changing. Then ?? Bliss baby. Outlets two to three weeks [ 500] hours. Yes Sir bend a cord it has to settle in again.
Just went through another break-in of our new elec. panel and dedicated lines. 21 days to be exact. ENJOY!!!!

My father, Bud, my mentor and best friend ever (after I became a father and finally grokked the Old Man) would look at all of this and throw the bullshit flag.  He was an electrician for 50 years and believed in using the best components from a rational POV.

 I learned a lot from my Dad.

 Buy the best tools and save up for them if necessary. 
Tighten it, wait 5 minutes and tighten it again.  He taught me about cold flow.

NEVER do anything stupid with 250..  You "might" get away on 120, but don't press your luck.

With 220-250, put your left hand in your pocket or an insulated glove.  The left arm is right next to the heart's natural pacemaker.

Make sure every connecting surface is as clean as you can get it.  Clean it, wash it, clean it again.

Be particularly careful with DC, especially when a battery is involved.  He almost lost his ring finger when he reached under the dashboard of a '48 Chevy he was rodding.  Shorted at the radio power input.  It was REALLY ugly afterwards for the remainder of his life.

He worked the last 20 years of his profession as the chief electrician and head of maintenance at the reactor at Sandia National Labs.

Even so, I can say that he would not believe that proper cables, greater current capacity, connectors or any of the things we take for granted as true.

I wish I could have showed him  :(. It would have stoked a fire in the Oldster's brain pan.

Miss you, Pop.  We'll talk, later :thumb:

Well guys, I got my hands on a little plug and play item and after doing just that, Can't imagine how we could have so many pages of write up on it. How many ways can you say something is effing awesome. Sources to DIGI to Majic to wall, oh my.
Can't say everything gained is from DIGI cause opened a space on the Majic for amp. Absolutely got improvement in the system.

Thanks Dave
Don

Just received my latest version DigiBUSS from Dave to use with my system. 

I have an original DigiBUSS as well to run the HAL MS-5 Music Server in the system.  The new one will be powering the dspNexus 2x8 DSP control system and Orchard Audio Starkrimson Class D monoblocks for the Magnetar open baffle planar speakers and servo subs.  This one is across the room from the first DigiBUSS.

Long time lurker here...I have been reading all of the PI Audio/UberBuss threads for awhile and just joined to say I GOT MINE!

Dave built me a FrankenUberBuss with an extra digibuss outlet on the side and Triode Wire Labs internal wires.

7 total UberPuerto's! 4 standard, 3 digi. Dave was able to do so to due the Neutrik Power Con 32A connector/30A dedicated line...Using a Triode Wire Labs High Powered Digital American power cable and I'm ready to rock!.... (Plus 3 more U.P.'s for dedicated outlets.)

Been burning in the power cable and the U.B. with any appliance and noisy device I could find in my house to plug into it. Should be ready to rock soon. Really looking forward to hooking my system up to it....

Dave's the best!!!

Hi Barry,
Yep, Dave’s the best! Thanks for posting. I’ve upgraded with UberPuertos and my BUSS allows the rest of my system to shine  :thumb:
