I have another question that is probably a bit off topic. I own Acoustic Reality Figaro ICEpower based amps (with the ASP1000 modules). These amps could deliver 500 Watts into 8 Ohms and 1000 Watts into 4 Ohms. Because they have high efficiency circuit and a switching power supply, they only need 20 Watts when idle. If you want to use isolation transformer in conjunction with these amps, is it still necessary to use a big one, let's say 2000VA so there would be no dynamic limitations? Thank you.
