These have been around for a while, though I seldom see one for sale. Of all the power conditioning hardware I've owned, this is my second favorite, behind the Isotek unit I just got myself for Christmas (or at least that was my rationale).
Anyway, this model of Z-Stabilizer really is kind of amazing. Just plug it in to a power strip or other power conditioner. It parallels the circuit, makes things sound better, and I hear no sonic degradation. Improved mids and highs, and no compression of dynamics.
It's not pretty, shaped kinda like a toaster. I painted most of this one black, so that it's not so noticeable sitting next to the equipment rack--especially if I turn it around so that it faces the wall.
Owner's manual included. $300 shipping included.
I also have a Wiremold L10320 power strip available. These currently sell for $89 + shipping (price went through the roof on these, I guess Wiremold figured out how good they are). I'm willing to sell it along with the Z-Stabilizer.
