Installing Dedicated Power Lines -- Need Advice


My general contractor is hiring a licensed electrician to install dedicated 20A lines for my audio system as part of a whole-apartment rewire and gut renovation.  While I'm sure the electrician is very capable, I'm also pretty sure he doesn't know anything about audio systems either.  Can any of you recommend a consultant or electrician who specializes in audio electrical I can hire to advise my electrician on how to best set up these lines?

Thanks!

hilde45- Very simply, and for the last time:

What they are saying is they have a power supply that is so perfect nothing can possibly make it any better.   

Do you believe them?
My new basement has a second panel and there is a grounding rod outside. I need to get an expert over here to check it out, tell me what exactly everything is and if it's done properly.

Thank you for the reference to that thread. Hearing the argument that "P.S. Audio claims they are perfect and why do you believe them?" wasn’t providing the technical details I repeatedly asked for. So I appreciate YOU reading and hearing my question -- and directing me toward an answer.

For others following this thread wanting actual knowledge, here’s key bits from the highly credentialed Almarg (RIP). He pretty much shows why the Decware claim (and tendentious anti-PS Audio arguments) are flotsam. Whether these products are right for me or anyone else is an open question. That has to be tried and listened to. But the notion Decware’s $1k conditioner would assist a $2k plus P.S. Audio regenerator is put to rest, for me.

Almarg:

"4) The fact that the power regenerator essentially breaks the path between ac from the wall and the ac input to the power amplifier, since the ac provided to the amplifier is derived from the regenerator’s internal oscillator, and is amplified by circuits that are isolated from the wall ac by the regenerator’s power supply....

"Filtering" of ac to me means something conceptually similar to putting an inductor in series with the ac line, and a capacitor across the ac line. Both of which tend to block high frequency noise components. And that is conceptually what a line conditioner does, while a regenerator will eliminate anything and everything other than 60Hz (not just high frequency noise components), including for instance 120Hz and 180Hz and other harmonic distortion which may be present on the power line.
...
…[I]n principle a power regenerator should do the best job. However, a good one, with sufficient output capability to power an amplifier and other components that may draw considerable current, will cost considerable $, and also be substantial in size and weight. The leading example that I know of is the PS Audio Power Plant Premier, which costs $2200.

…A power regenerator is an electronic component which contains internally a 60Hz oscillator driving a high capacity power amplifier. Its 60Hz output is what powers the audio system, and the ac from the wall is only used to power the regenerator itself. So in principle the audio system will see ac power that is very pure, and essentially free of noise, harmonics, etc.

A power conditioner is essentially a filter, which passes the 60Hz ac from the wall to the audio system, while attenuating to some degree the noise and other spectral impurities that may be present. Some of them also provide outlets that are isolated from each other to some degree, so that noise from digital components can be prevented from coupling into analog components via their power connections."
I believe ASR has acquired one of these regeneration devices and has it in the queue for testing.
A quick tangent, but

Thanks to the late great Almarg.

I've been away from  here  for some time, and hadn't heard about Al, and just discovered the news of his passing.I wrote this with tears in my eyes: I never met Al, and I was able to understand only a fraction of what he wrote, but I always marveled at his smarts, generosity and grace.
There seems to be a lot of concern about conduct/misconduct on Audiogon these days: good to remember the the shining example Al set.My speakers are the same ones Al championed for many years; I'll play something for him tonite.
