Since OP’s amp uses an EI power transformer which does isolation already, adding a separate isolation transformer may not give any benefit.
However, if the isolation transformer is wired in balanced manner, then it can help.
Not sure for power conditioner my amp or not.
Hi, I have an VTA ST-120 I built using KT88C’s for my 2 channel. I have all my equipment running through a Torus Power TOT MAX Toroidal Isolation. I have heard 2 different versions on what to do. As far as what to plug my amp into. The wall or the TOT’s? I know this isn’t a "power conditioner" such as PS Audio sells. Should I keep everything plugged into the TOT, so all my grounds are the same and it has the optional surge protection? Or straight into the wall? I tried the wall once, but didn’t hear a difference really. But I didn’t test for long and not sure I ever got to the point of drawing too much power from the amp. Which is the best way to leave it? Thanks! Scott
