I am demoing a PS Audio 500 in my system and I am liking it. However they don't come up too often and I have read that because they are an active device there are reliability issues with them. So I am considering passive conditioning. Who make good power conditioners that I should consider?
-
The PI Uberbuss
-
Passive: Balanced power conditioning from Equi-tech or BPT
Active: PurePower
An active power regenerator like PurePower or PS Audio is just a big power amp, that plays only one note = 60Hz sinwave. If the amp is designed well and the output devices stay well within their safe operating area then it will be reliable.

Jim do you already have dedicated lines with upgraded outlets already? I would think that would be enough for power filtration. What ails your system that requires power conditioning?
Since I can't do dedicated lines I have a couple of band aids. For me I guess I use a lot of passive power conditioning in the form of Isolation Transformers. Due to budgetary constraints I use a combination upgraded outlets, Emotiva CMX-2 and CMX-6 power filters, Topaz Line Noise Ultra Isolators and Tice Power Block.

Yes I do have dedicated lines. I never knew I had noise in my system until a friend lent me a P500. There was an improvement. Moral of the story: Stop demoing equipment if you don't have a problem :rofl:

Find a conditioner that uses 240v 20amp balanced. Needs two 15 amp fuse space in your house fusebox like your dryer. Install 10gauge to the wall. My Torus rm20 is like this and it lights amps up a few notches. It is a passive output not active. You Will never look back and it will become the single most important component in your system.

Just spoke to a couple of quite knowledgeable guys in Vegas recently (manufacturer and dealer) and they use the Equitech unit.

The equitech looks good but their transformers go from single phase to 3phase from the house fuse box. 3 phase in home audio is pointless and there is no reason to spend that kind of money. Which Leaves only single phase products as viable. 2 phase is where it's at. IMO of course.

No transformer can convert single phase to three phase power. A transformer can only invert phases of separate secondaries.
Equitech may offer 3 phase products also, but that doesn't disqualify their single phase products from audio use. A balanced transformer converts a single ended 120V mains into +60V 0 -60V output. Ground floats, eliminating ground loop related hum. Lots of yuk is filtered out and many benefits from the balanced power. The large transformer adds reservoir of magnetic energy to especially help amps with relatively small transformers and storage caps due to high voltage (tube amps.) The only drawback to Equitech or BPT is the mechanical vibration of the large transformer. For tube amps it is lightning from heaven.

Is Torus balanced power? I thought it was just big isolation tranny, single ended on input and output? Do they also have true balanced output versions?

You can order them Fully balanced 240v 20amp from the fuse box. There is not much to them other than the isolation and step down to 120v to each of their 8 outlets. They give you a fully balanced power cord from the wall to the Torus.
This is imo the only way to apply a conditioner to SS or high power Tubes.
I got the transformer nut holding the transformer down out so the mechanical vibration is equalized into the chassis. Plus its sits on its own platform off the floor.
I have never heard a Single Phase Torus at home but only showroom but they do make their own transformers. They are transformer supplier. The smallest you can get is 20 amp or 10 amp per phase off the fuse box.
3 phase are for chefs..lol. Their stoves will operate at 240v and they can get another 120 for elements or microwave, clock ... Whatever, Completely pointless for home audio
Furhman makes 240V dual phase also. This is the only way to meaningful wire a conditioner. YMMV

2 phase is where it's at. IMO of course.
FYI - Balanced 120v is still single phase. The most common residential and small commercial service in Canada and the U.S., single split-phase, 240 V, features a neutral and two hot legs, 240 V to each other, and 120 V each to the neutral. Neutral wire is the return conductor of a circuit; in building wiring systems the neutral wire is connected to earth ground at least at one point. North American standards state that the neutral is neither switched nor fused except in very narrowly defined circumstances. The neutral is connected to the center tap of the power company transformer of a split-phase system.
A balanced power transformer simply lowers the voltage of each of the hot legs down to 60v rms so that you can get 120 by wiring across the 2 hot legs. While you are referencing the two hot legs to each other it is still a single phase system.
Three phase power is most commonly used in the power distribution grid because if it's increased transmission efficiency over single phase operation. End user use of three phase power is most commonly found when powering large machines or heavy duty motors because of the smoother operation and lower level of surging compared to single phase operation (would be nice for a TT motor is it wasn't so damn expensive to bring three phase power into a home.)

Nope not true, 240v 2 phase or balanced means running two 15 amp hots (no neutral) plus a ground into an outlet. Mine is 240 20 amp but it could supply 240 30 amp which is available with that same circuit. I can get a bigger one in 3 phase but really point less u lees you got some bar PA thing going on.

No apologies needed, it is a common misinterpretation.
For those who are less conversant with power grid technology, in a residential split phase system you have two hot legs (call them A & B) and a Neutral leg (which is connected to ground in your circuit breaker box. From this configuration you can get 240v across the two hot leads (for stoves, dryers, hot tubs, large air cond. units ect.) or 120 volts from either hot leg to the neutral. Although there are two hot legs, it is still only one phase (A to B, which are 180 degrees apart).
In contrast a three phase system has three hot legs (A, B and C). Therefore you get three separate phases (120degrees apart) A to B, B to C and C to A. (You can also reference each of the hot legs to a neutral just like in the split phase system).
(Pete, as our resident commercial power expert, please correct any misstatements I may have made.)

Not to mention you get 45 amps on tap. It is awesome but the cost of these transformers conditioners are in the $10k range. Too much when a balanced config can be reached with 2phase. That is all i was saying.
You want this for big massive monos blocks but its better to use 2- 20 amp balanced since you can get the thing right next to each amp. With 3phase its stuck on some wall or in another room and the amps need to reach over with long cabling. It sucks for audio imo. I can see it useful for HT.

This is as close to a shill post as you can get.....
..but...
Chris Hoff at Balanced Power Technologies ("BPT") has brought his equipment to a few audio shindigs in STL and has impressed the masses with what his equipment does to the sound.
His stuff is above my paygrade, so I can't speak from experience in my system, but I've heard what it does in other guys systems and can vouch for that.
Have a nice day.

Well see how we're all shillin (chillin') here, it was Chris Hoff's BP2.5 balanced power conditioner that got me motivated to a higher end audio setup. I bought my 2400 watt conditioner back in 2002 for my TV, just looking for the best possible picture for my C-band system. While the conditioner did definitely sharpen the picture, what it did for my mid-fi system back then simply blew me away. That was around 55K ago at a time when I didn't even have a computer, just Webtv.
Since that time, my conditioner has made many trips back to Chris for upgrades that are standard fare for today's BPT's.
Today I have a dedicated circuit leading to a PI Audio UltraBuss (parallel filter) and the BP2.5 balanced power conditioner plugs into that, then everything in my A/V system plugs into the BPT. Other than the BPT leading me to bankruptcy in 2010 (losing my job in 2007 also helped), I couldn't be happier with my dead quiet highly dynamic system.
And that's my BPT/UltraBuss shill that works for me. :D
Cheers,

I was reading up on 3 phase and pointed out was the inaccuracy of balanced signals. Balanced lines are not perfectly balanced. Slightly out of phase. Which probably means a voltage regulation is used to keep the thing in phase. But Holy sheeite how much would that treament cost? I like it though and I take it back on 3 phase. If I won the lottery that is what I would do.
Tonight i will take pics at my work and show you guys the 600volt system in the basement... Lol. Its antique but its awesome.

It may be old, but I don't think it is really antique. That is a pretty standard commercial service entrance and if you were to look a a new one that was put in a recently constructed building you would find that from a technology standpoint it would be pretty much the same as what you have there. contact switches, fuse and circuit breakers have not changed all that much over the past 50 years.

The panel right behind it (you can see it) powers the building. But we just had a new 600 volt 3 phase supply installed with breakers to our platform lights. It cost $3500 (i was told that price but i am skeptical)

If that unit is as old as you say it is the oil inside the transformer is likely to be full of PCBs. So if you ever walk into that room and see a slimy puddle on the floor, treat it as a toxic waste spill and do not clean it up yourself.

Before we plunge into a conditioner some basics first. Get a circuit tester and multi - meter. measure to see what voltage you have at listening time.
Check the circuit with tester to verify proper wiring. If all wired right and we have 122V good.
Remove existing receptacle, disconnect wires and clean them. clean receptacle as well. reinsert wires after treating with pro-Gold and tighten well. Change the receptacle to a 20A industrial type.
Now we can try conditioners. There are several ways to do such. One is a isolation transformer plugged into dedicated circuit then using a power conditioner plugged into that.
Isolation of digital gear is key to any power set up. If one can have two dedicated circuits using one for digital and one for analog even more affective.
If not the conditioner selected must have a dedicated line for digital.
Some designers and power experts suggest no conditioning of digital gear only the analog. Lifting the chassis ground [ if available on unit ] on digital is a plus. Power must be grounded but not the chassis. Can be a big improvement.
One can try regenerating power conditioners, Balanced, brick wall, etc. They ALL have an effect on the sonic outcome. Not all conditioner work with amps well. Loss of dynamics can be a result.
To date I have tried numerous conditioners. The one that does the least harm sonically is the Uberbuss. Using one for digital and one for analog fed off one dedicated 20 A line.
No matter what PC used the Alan Maher devices were installed at the wire entry of the elec service and one in the receptacle box of the dedicated line. These devices are never going to taken out. Yes a royal PITA to settle [ 3 weeks] however worth every minute waiting. Result is more dynamics, more info and deeper bass.
Almost forgot some more basics. All power cords should be lifted off the floor. None should touch each other. Keep at a minimum 6 inches apart. Digital ICs should be shielded as well as TT ICs. Keep power cords away from internal in wall wiring as well 6 inches minimum. Keep conditioners away from gear at least two feet.
Wire management is a part most neglect. ICs, speaker cable, power cables can interfere with each other so get to work and my bey you will hear better sound.
A disclaimer I sell the Uberbuss.

Charles, I'm starting off with a good foundation. New Electric service, panel, breakers, dedicated 20A line with Hospital Grade Outlets. Although the regenerator sounds good I can't ass the power amp to it. I remember reading to go passive with a big ass torroidal xformer. Unfortunately my power cables are touching the ground. i guess they are "grounded" :lol:

I think hockey pucks have to much surface area to be effective. Never tried though. I read online about above ground power transmission. They used those power cable guides. They are made of ceramic, assuming there is an electrical benefit since they wouldn't use something that didn't worked good for effective power transfer.
So i have been keeping an eye out for anything ceramic :lol: to hang or make contact on cabling for a riser.
I know its real 3rd floor wacko hospital nervosa stuff but hey i am in it for the long haul. :thumb:

Overhead power lines are mounted on ceramic guides not because of anything to do with the transmission of the power, but rather just the opposite. The ceramic material is used for it's insulating property. The reason it is there is to support the cable physically while making sure that none of the electricity is is conducting flows into the pole or metal tower that it is mounted on, which of course is stuck in the ground and would cause a dead short. This is not an issue with the cables we use in our audio systems since they are all insulated and well protected for the working voltages that they carry.
And while the surface contact area of a hockey puck under a cable is greater that that of some other types of cable supports, one three inch diameter puck placed \every three to four feet is still a heel of a lot less contact area than laying the entire cable on the floor. And seeing that I know Jim is a hockey coach, I knew he would have a bunch of old pucks laying around which make the whole experiment...... free. :thumb:

Got that right! Question: Do transformers in the conditioners have an adverse affect on sound?
-
Hey Scott good to see you posting here. Hockey pucks will act as vibration suckers. They reside under my washer and dryer. Dead quit now.
For cable lifters I use the ceramic insulators used for temporary lighting on construction projects. Some are hung by shade rope with a loop to hold ceramic insulator.
Be advised that when you move your cables allow 2 to three days to settle again.

Question: Do transformers in the conditioners have an adverse affect on sound?
No. You already have transformer in this role, your power transformer. As any hardened magnetics addict will admit, more magnetics are always better! Any transformer power conditioner will do a few positive things: filter out high frequency noise from the mains, provide large reservoir of energy in magnetic form, reduce source impedance of the power (so says Torus.)
If your power conditioner is also a balanced power converter, then you add the benefit of reducing common mode noise in the system and have a quieter floating ground, as well as the above advantages of any transformer. Read some of the equitech papers for better explanation than I can remember. The disadvantage with the large transformers is they hum very softly, but if you require dead silence then you need to isolate it mechanically and acoustically.
The regens are great too, as long as they have enough power. I would buy a PurePower unit in a heartbeat. It powered some of the best bass I've ever heard with Legacy Focus SE and Edge 400W stereo amp.
-
Got that right! Question: Do transformers in the conditioners have an adverse affect on sound?
Yes, what you are asking it to do is exactly what the transformer in an amp or dac, preamp already does. You really do not need another transformer between the component and the local neighborhood transformer. There are advantages and disadvantages. Its crap a shoot as to whether it work or not.
The advantage is the transformer sets up a single point of reference between the numerous component transformers and the local neighborhood supply. This is good since that reference will see the local neighboor transformer with much less impedance than multiple smaller transformers. This is good for power draw since your stereo is in competition with every other appliance in the neighborhood, including your own house.
The disadvantage is big tranformers tend to hum and attract noise. Especially if you have two big ones in series. (Everything gets amplified) so what can happen is that noise gets amplifed through speakers. It ends up as hash. But if it works it works great and the smaller transformer are always saturated and never get starved too.
Big huge amps should sit on their own with their own 15 amp supply imo. But smaller amps can sit with the rest of the stereo hooked up into a conditioner.

OK so I went on a spending spree today. ln addition to a TT I also purchased the Exactpower power conditioner. Don't know much about it but I guess I'll find out.

How does the Exactpower sound in your system?
-
well, I had to return it. The unit I got had a bad winding and it had a 60hz hum. Lucky the guy was easy to deal with. Now I am looking again.
BTW, other than the hum it made the system sound better.
-
For what it is worth for the last at least ten years I have been using a
brick wall, same as a Zero Surge power filter and it more than meets my requirements. Been there done that with all the power crap years ago.
$250 and your done. 8 outlets. The Furman's are supposedly good but I have not heard one in my system. No need to get that elaborate or costly.

OK so I've been keeping my eyes peeled :shock: for a power conditioner. The last one I had to return as it had 60hz hum. (Bad winding) I did see a nice BPT but at 80 lbs I couldn't help but imagining myself carrying it back to Fedex in case it needed to be returned. So, I have had good results demoing a P500 in my system. Overkill for what I need so I just bought a P300. Just enough juice for my low power equipment (Pre/Dac/TT/CD). I figure it is a low risk since I know the P500 sounds good in my system and it weights a lot less. :thumb:
-
Ok so I am reviving this thread. I returned the P300 that I purchased. I have since purchased a PS Audio Powerplant premiere. It is capable of handling all the components including the power amp. I am still in the evaluation phase. It is not one of those pieces that can be easily A-B'd. So far it sounds as if there is more lower level detail coming through as the imaging seems better. Dynamics seem unaffected (not better/not worse). more to come.
-
Jim stop wasteing your time and audiyion an Uberbuss, Digibuss and Bussstop for DC on AC. The most used power products by manufacturers at shows. There is a good reason why.
charles
-
Jim, the PS AUDIO P300 is basically a power amp and should show some sonic improvement as its power supply caps break-in. It should have very little harmonic distortion of the 60Hz waveform. If it works out for you, you should have the AC noise problem licked.
Scotty

I bought a PS Audio Power Plant Premiere. It is more current that the P300 and much more capable. It sounds very good in multiwave mode. I have not done an A/B compare with/without the PPP in the circuit.

The PI Uberbuss
What is the technology used in Uberbuss?
At the insistence of rollo I just registered here and this looks like as good of a place to get my feet wet as any.
Th UberBUSS is a passive, parallel filtration device that is non-current limiting and uses no coiled inductors in its construction. A simplified description is as follows:
Power inlet (IEC, Neutrik or hard wired)
The Brick - primary EMI/RFI filtration - a proprietary construct
Power Factor Correction - produces more available current under the curve - built from Type 'X' capacitors
FinalFilters - individual high frequency filters on each receptacle
Current throughput capability 40A
All of this is mounted in a non-magnetic, non-metallic enclosure. I have found this to be very important to eliminate eddy currents that will color the SQ.
Standard receptacles are modified Pass & Seymour 5362A receptacles with no magnetic components and are cryogenically treated for lowest noise and conductivity.
I developed these units for use in recording studios after auditioning available units that frankly speaking didn't sound very good or dramatically blunted transients.
It is an easy solution that was hard to figure out.

Dave! Great to see you here! :thumb:

Welcome to AN, Dave! I've heard a lot of good things about you and your products over the years.

Thanks, everyone. It is good to find a new home.
Since I left (was booted) from that "other place". I have been cruising the forums to find a fit. Rollo has been after me for a while to land here. Low and behold after a lot of lurkin in other places, this place makes sense. Not in a numbers context, but quality. I'll take quality over quantity every time. After all: that is how I built my business.
I really appreciate the warm welcome and it is my intention to be a "quality" contributor here. Listen if you will... slap me if I need it 8)
It's "only" audio, but that is what this is all about.

Hot damn, Dave!
It's nice to see you again. Pull up a seat, sit a spell.

I moved Dave's 1st post from above to his own thread, so we can talk about him and his stuff more focused.

Dave...? yeah Dave. Dave's not here.

Somebody should send me one of these Uberbusses to try out. It's got to be in 240V though. I wouldn't deliver a limp 120 to my system and call it a stereo. Same way i would not stand in front of my wife limp asking to get down and dirty. :D :thumb:

Thanks everyone. I think this is going to be fun again. :thumb:

Dave...? yeah Dave. Dave's not here.
I was, but now out to the shop >>>>>>>>>>>

This is the kind of power delivery i expect or it gets boxed and sent back. https://vimeo.com/4366695
Also no nickel plated copper to the outlets or anywhere.
Good Talk!
haha welcome aboard :thumb:

I get it. Instantaneous and plentiful power with no current limiting other than that inherent in the I/O.
Nickel just sounds bad: thin, edgy and harsh depending upon the resolution of the system.
I chose the P&S 5362A for its mostly brass construction. They come with steel joining pins in the back. I pull those and replace them with 6-32x1" brass screws. This leaves the 10-32 neutral crews which I will replace upon request. One other tweak to the standard receptacle is an option to polish the existing contacts. All of his makes a killer low cost ($60.00) receptacle. Cryogenically elated, of course.
