I'll have to use a 220/110 step-down transformer for my amp. What would be a difference between auto-transformer and isolating one for the mentioned application? Since the last ones are more expensive, how critical is it?
Thanks guys! I'd just ask if you can recommend some specific brands or sources of the transformers available in North America (or if you have any NOT recommended, also to mention them...)
Sean, you mentioned vast difference in quality... Do you now anything good or bad about those offered on sites such as http://www.220-electronics.com/, etc? On the mentioned above web site 1.5Kw transformer costs about $120, made in China. On the other side Hammond from Canada sells 1.5Kw for about $350. I guess there is something in that, how can it affect sound?
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?
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.
