Powerconditioners for digital?

That sounds like it would provide total isolation, and conditioning.
Did it have have a significant effect on the sound?

Hi Sabai. What is your DIY conditioner? Your isolation transformer? Have you tried an Equitech 2Q just for comparison? Ever try the MIT ISO HC and/or Z Stabilizer 11? How about the original Z Stabilizer?

Hi Listener. That original Stabilizer powered on whenever plugged in. The switch was not an on/off but rather for A or B setting options. The light burning out/not working was not uncommon.
The unit is dead silent-plugged in or not :). I doubt it is 'broken'. I have older Spectral Reference pre & amp and MIT reference power cords, i/c's and speaker cables. The effect of your unit is immediately discernable in my system-and I still use the Stabilizer in a rather unique applications-chosen by ear.
Tell me about your system and I will suggest uses. We can chat.
