AC Regenerator

Just to mention all is not perfect in the regenerator world. The very small but forgotten problem of some tube equipment cannot use the PS Audio balanced power/Technical power output. Directly heated triode just cannot be used with  it.Then a few pieces of equipment DIED when the various multiwave features are used. (now THAT may be solved with newer models? But with older models the various multiwave modes CHANGE THE actual AC VOLTAGE to as high as 130V measured, even though the meter on the machine says 117. To read up on that you will need to Google some.
These turn into problems few, and far between. but have happened.Also the fact upping the AC frequency with older PS Audio machines may cause problems with the equipment connected. usually just lowering the AC frequency back some is all that is needed.Sadly most of these things are not really written about on the PS Audio website.    
I like my PS Audio P600 as much as anyone. But it is changing things, and you should know what it is doing, not just think it can do no wrong.

Aquired the most recent PS 15 Direcstream PowerPlant and repeat the previous messages.  Just sounds better all the time.  The newer 12, 15, and 20 are pricy but are more efficient, less heat, and bigger headroom.   With that all said my guess is their are some good deals to be had on the recent "older" generation 3, 5, and 10 PowerPlants.   I live in a condo complex with a lot of dirty power.   THD is going from 3.0% to .1%.   

I am so glad we have clean power in Australia: 240V +/- 2V and 50Hz +/- 1Hz.

In any case, I use a Monarchy Audio AC Regenerator for my line stage and to be absolutely honest, I can’t tell any difference with it in or out of my system. Having said that, the Regenerator absolutely bleached the sound of my 6W/channel SET power amp and equally dried out the sound of my Leben phono stage.

If you have "dirty" power then maybe, but for mine, power conditioning otherwise is a marketing beat up

Also, I thought quality components had quality power regulation as part of their circuitry?

I can’t praise Eaton Power Quality data Center UPS products highly enough. There is a marked difference between these on line double-conversion UPSs and substandard SOHO units. I use the Eaton Powerware 9130, which produces a pure, clean sine wave output, and can give detailed reports about utility power quality and of course load levels and runtime. The only downside is that these UPSs are fan cooled, and therefore cannot be used in the listening area. I have my units in the basement, freeding a sub panel that serves dedicated branch circuits to my system. 

Well, that should probably be extremely high quality components when we have a current like that. I didn't try Gryphon or Lamm in my place, this would be interesting.
Elizabeth, that's good to know. I think some turntable motors dislike changed frequency as well.
