Anyone heard of Powervar conditioners?

Blueswan, how did you test for the audio compression? Or was it just by A-B listening comparisons?

I've tried a bit of listening comparisons (with and without Powervar,) although I only have my transport, DAC, Pre, and phono-pre on it, and didn't notice significant changes in the sound. My amps and subwoofers plug into the wall.

Your input would be appreciated, thanks.

The compression I noticed was a more 2-dimensional soundstage. The front to back depth was noticably more forward, although very very clean and quiet. I have a much older model Powervar, late 1980s vintage, maybe the newer ones do not have this issue.

Blueswan, thanks for the tip. I'll do some critical listening this weekend. You are not the only one that has had this criticism.
Much appreciated.
