PIAUDIO DIGIBUSS

[tmazz]

My DigiBUSS arrived late last week.  I installed it on Friday evening. CD Transport, DAC, TV, Blu-ray, and cable box plugged into it.  DigiBUSS plugged into UberBUSS. Hypex NC400 monoblocks, preamp, and analog front end plugged into Uber. Full loom of TWL PCs. Rollo put about 150 hours on it before shipping since I was on vacation.

Another great product from Dave at PI Audio. Of course I bought it for the transport and DAC and am really happy with my digital sound.  I think what surprised me though was the improved picture quality on the 55" TV.  Nice bonus

Not sure if the Digibuss has enough capacity, but if it does you might want to try plugging the monoblocks into it because they use switching power supplies and produce the same kind of noise that your other digital components do.

Every product that I make has current handling capacity in excess of 25A @ 125VAC to mitigate current limiting.  Each outlet is individually filtered and will prove some isolation between every other outlet.  My UberBUSS has one filter package per receptacle, the Digi has two.  The Uber, however, has the PFC network that is a monster for unleashing dynamics with linear power supplies.  For those with linear power supplies, Carles Rollo will have an UberBUSS to put out on the road for audition next week.  Ya gotta try it!

HTH,

I did not know what the specs were, but it sure sounds like the Digi would have no problems powering the amps.

I'll have to move some things around to try the amps in the Digi as I only have one outlet free on it now. 6 available plugs ad I have 5 being used. I'll move the Blu-ray player to the Uber as I don't use it very often. I'll report back next week.

Thanks Don, enquirering  minds want to know!

I read all the posts again as I'm talking with Dave about a digi for my particular needs.   Still thinking about receptacles etc  Charles, I forgot you carry these or I would have been in touch. It'll be nice to banish those digital nasties

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

I'd like to hear others experience.

Thanks for the info. No matter what it looks like on paper, you never know for sure until you try.

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.

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.

Inflow power systems

That should have been:   Low power systems

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.

  .  So y'all thought it was BS eh. 
  Thanks RPF.

Auditioned the P.I. Audio Group DigiBUSS yesterday in my system.

Guess what? It's not leaving my system!

It will be featured with the LampizatOr Komputer & Golden Gate DAC at my shindig on May 21st!

Yet ANOTHER     for Dave Elledge and his BUSS line of products!

Thanks, Pete.  The little things live close to the noise floor, huh!?
