I don't know--I'm only using it for my DAC. I figure that if I had another line conditioner like the Jon Risch DIY I would plug that to the Power Var and then the CDP to an outlet and the DAC to another. That would keep both devices isolated. I tried hooking my Cambridge D300SE CDP to the Power Var and the Soundstream DAC-1 to my Tice A/V Solo and the results were not as dramatic. Seems the DAC is the main offender in my system and *really* needs to stay isolated. For $55 get two--one for digital and one for analog. You can still plug the line conditioner to the Power Var--or vice versa.
It was Sedond who originally e-mailed me this link from Harmonic Discord:

The original Poster, Audiojerry, emailed me that he used to have a Tice A/V Solo like I do and he likes the Power Var better for digital. Said he ordered a second unit for his analog components.
Sedond ordered one Power Var for his infamous modded ART DI/O. He should have received it by now and will email me his feedback pretty soon.
For critical line level components I would like to try one of Jon Risch's balanced power transformer designs. Risch knows what he's doing...
