"Magic" of Z Stabilizer ll??

I have no idea why it works, but it certainly does in my system; I run my amps through it (200w ARC tubes). I have tried a number of upgrades over the years and have always found that the Z Stabilizer sounds better. MIT still makes a version III although they don't promote it.

I used a Z-Cord II on it for years and have upgraded a couple of times since. Its now a Nordost Valhalla.
