Powerconditioners for digital?

Shunyata, Equitech, Sound Application?
Check out the VH Audio Plasmatron. It is specifically designed for digital and computer audio devices.
Pure Power, full regeneration with a battery backup, you can even unplug them and run solely from the battery! They are amazing!
I run two isolation transformers in series and a power regenerator plugged into #2 with DAC/transport plugged into the power regenerator:

isolation transformer > isolation transformer > power regenerator > DAC/transport

Works much better than any other configuration in my system.
That sounds like it would provide total isolation, and conditioning.
Did it have have a significant effect on the sound?
