I have tried both Equi=Tech and PS Audio PP600. Both have balanced power and can be be hooked up to a 220 volt line ( tried the larger Equi=tech which requires 220volt line and plug) PS Audio you have a choice.
I found that there was no comparison between the Equi=Tech and the PP600. The PP600 had much more depth, wider sound stage and realness to sound. Plus you can use great power cords with the PP600 such as PS LabII cable, the Equi=Tech doesn't have a detachable power cord. If you have power flucuation such as I do, only the Power Plant will keep power steady. Needless to say I bought the power plant 600.
The best way is to try each out in your system both ccompanies have 30 day try out period. George2
