Best Power Conditioner?

PS Audio is the only one that actually reconstitutes the AC Wave and cycles. It draws a lot of current and costs quite a bit, but of the above, I would choose it first.

The Hydra

I agree with KF...

I have used PS Audio with very good results on less expensive gear (eg. Sunfire Amp, Theta Miles).

Improvement in the Theta was nice but the sunfire was a different story...
It was like I had bought and brand new amp. it was incredible..

In my opinion, the sonic improvements gained by a regenerator such as the PS Audio are proportional to the quality of your incoming ac and the power supply(s) in your gear.

When I upgraded to very good amps (Atma Sphere MA1 mkII.2) the improvements were positive, but far less dramatic than the sunfire.

I still use a PS300 for front end.

Although, I was most suprised by the installation of dedicated balanced ac lines with good receptacles?

I have heard great results with these and it was somewhat less expensive than the very big and good generators/conditioners.

I have not heard the other choices but have read great reviews on Hydra.

You may want to add Foundation Research into your list. FR makes passive in-line conditioners that take the place of an aftermarkter power cord. These are about as expensive as most active power conditioners but I believe do as much if not more that most in the list above.

Of course, the Foundation Research in-line conditioners, passive conditioners that they are, do not regenerate electrical current.

Foundation Research is a little known company a few hours outside of Toronto, Canada with Ed Wolkow as the Chief owner/designer. He also makes SS amplifiers and tubed preamplifiers that are supposedly out of this world. His new V6 preamp has been touted by some as the very best.

I am using two LC-1's for my source and pre and an LC-2 for my amp. At the very least, you would notice a much lowered noise floor, better imaging and soundstaging, and a vast reduction in sibilance with the addition of each LC into the mix.
