Transformers: Auto- vs. Isolating

Sean, thank for the reply. I'm in Canada, but I may have to go to 220V/50Hz area for some time. After my recent upgrade of almost whole system, I can't afford 'perfection' anymore :), and thus I'm looking for the economical way to feed my system with European voltage, meaning to compromise sound quality the least possible. Your advise?

Any more details, please!

This discussion is an example of a philosophy of sizing AC power components (transformers, power cords, house wiring, etc.) so as to provide the peak power requirement, which, as we all know, far exceeds the average. This is necessary because there is no device (other than the spinning momentum of an alternator) that can store AC power.

However, almost all the AC is used to generate DC power, and there are devices, capacitors, that store DC. At one time a popular Mod to audio power amplifiers was a bank of outboard capacitors. It seems to me that this is a better, and less costly, way to provide greater reserve power.

I'd say it's more about a possibility of compromise: if 'voltage coverters' such as those from www.220-electronics.com may be used (virtually) without hurting the sound. There is no problem with sizing with them, unlike the real isolation transformers, which are much bigger, heavier, expensive, and less available.

Ok, it's 26lb, not 30... close though. Can't find how bad are they...
