Here is my progression. with my system, I started out using a Monster Power Signature HTPS 7000 unit, with every low level piece plugged in to the Monster (pre-amp, CD, DAC, TT, Tuner, Phono Stage) and the amps into their own dedicated line to the panel. Note, the Monster also had it's own dedicated line. Three dedicated lines. My favorite store in San Diego had 2 PS Audio PS600 units for sale used. I took them home for a week and they blew immediately. Apparently, they are just like massive amps and the capacitors went bad. The store replaced all of them at their costs and I took them back home along with a Transparent Power Isolator 8 Conditioner. I did directly A/B comparisons between the Transparent unit and the PS Audio units with the Monster out of the system. The Transparent Power Isolator unit made the system sound really better than the PS Audio units. Don't get me wrong, with the PS Audio units, it still sounded great. Just better with the Transparent unit, and the PS Audio units have regenerators. That is my chain. 1) dedicated lines whereby the small signal equipment are all plugged into the Transparent Power Isolator and into a dedicated line to the panel. The Amps (Mark Levinson 23.5 for upper panels of my speakers and ML-3 to bass units of my speakers) have their own separate dedicated lines to the panels as well. And last, I am the first house on the power circuit of my neighborhood off of the transformer. So, my line voltage is clean and high all the time. But, I strongly recommend before isolators, regenerators, conditioners, etc. That you pay a few hundred bucks to a qualified electrician (or do it yourself if you are qualified), to install dedicated lines first. The Transparent unit is actually really good.
