AC Regenerator

Clean power, regardless of how you accomplish it is to me the largest factor in a musical system. Put another way, the further up the line you improve the signal the greater effect you have throughout the system. I use balanced power throughout and it's great. I'm sure the PS Audio is great at this also. Reproducing music with dirty power is a compromise throughout. 

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.
