Kind of funny that you bring this up, as I was discussing this with a local shop today. Your dealer is talking about an isolation transformer and he is right on the money. There are a couple of different designs for isolation transformers though with some working better than others. Most any of them would work well for what you want it for so long as it could pass enough current. That is one thing to consider with amps for sure. As to using them for sources and preamps, etc... the ideal set-up would be a properly sized transformer for each component. I may try doing something like this sometime shortly.
My experience is that "old school" iron core transformers work better than "high tech" toroidals in isolating noise, so that would be an easy thing to check. Sean
