Power conditioner help


Hi All,

 Posting this here since there is no section devoted to power products. I also posted it in the miscellaneous section. 

If you had a choice between PS Audio P10 power plant and a Transparent Powerisolator Reference, which would you choose and why? Both available at reasonable prices, though P10 is still quite a bit more. I have a pretty high end system with a Musical Fidelity NuVista 800 integrated amp, NuVista CD (the new one), Scoutmaster turntable, SDS/ADS, Herron VTPH2, Wilson Sashas, and all Transparent Ref MM2 cables. System sounds great, but my present Powerbank 8 is quite old now, so I want to upgrade it.

Thanks for your opinions.

Totally agree with stingreen, is take a Purist power cord over any power conditioner.  I have found all conditioners to be one step forward, two steps back. I.e. Their might be a perceived reduction in the noise floor, but the dynamics are softened, or worse...anyway more harm than good
So, based on comments here and elsewhere I called Transparent and asked about their power conditioners. The young guy was very nice, and he tried to be helpful but alas, he could not give me a technical explanation for his marketing/sales spiel. This is the problem I have when I call most audio companies and ask for help in understanding their benefits at a technical level. For power conditioning gear I really expect to get my basic questions answered.

What I got was that the Transparent gear uses a parallel approach in how they voltage clamp and remove transients/noise. I heard the name "avalanche diode" repeatedly, but when I asked how that worked... no information. I asked him to contrast their approach with the approach that power regenerators take, and he said "we don’t really follow other vendors in this space" -- a fair statement, but I was a bit put off as well. I do not want to create a negative impression about my experience: But I did not get technical enlightenment on much of what Transparent does or how the overall category or power conditioners works and (especially) how they might negatively impact music.

What I will say is that most of what I have read and most of what I have heard strikes me as non-technical and not empirical at all. I simply want to know why some people (Transparent sales included) firmly state that when they listen to audio gear through a regenerator they believe that the sound is constricted and the sound stage suffers. I take this as BS. The only way that can happen is if the device itself restricts the FULL CURRENT THAT THE ATTACHED AUDIO GEAR NEEDS. If your regenerator provides more than the maximum draw, how is it restricting anything? In fact I’ll go further and say that if the regenerator transformer is large enough, you will get more power at peak sections of music than the wall would be able to provide!

So, if you really understand what is happening: Please explain it ...in technical terms. (Remember, I have not suffered this problem with my regenerators, and my attached audio gear does not draw more than 50% of the regenerator’s rated capabilities. It is power, it is ample and it is clean power. Please explain.)

Take a look at Jon Risch's comments in the link below.  Perhaps the regenerator(s) are sized appropriately for the RMS current, but starve when the peak requirements occur?

I'm certainly no expert on this, just passing along info from someone who knows way more than I do.

When I call Transparent for information, which has been many times over the years, I have  always gotten very good and clear explanations as well as a excellent customer service and an attitude of being helpful and willing to answer the questions that I have. Try calling and asking to speak to Demos or Josh. 

Before money is spent on conditioners, you owe it to yourself to listen the Purist Limited Edition power cord, or better yet the 25th Anniversary AC power cord, or very best 30th Anniversary AC power cord.  :-)

As to these ratings on the conditioners and regenerators, I think bcowen may have nailed it.  I.E. they look good on paper for RMS, but when the transient of a big pop on a snare drum, or the dynamic pluck of bass guitar, everything is boringly softened.
