High Quality Step Down Transformer?

nearly two years ago i moved from nyc to hong kong. there was (and probably still is) a shop called overseas appliance (or overseas electronics). they sold me a pair of "big star" step down transformers. made in china. i'm happy with them--as happy as you can be using step-downs. they run my cj tube gear and they ran my cal. cd player before i retired it. good luck.

sorry, the name of the transformer manufacturer is "seven star" not "big star."

Try the PS Audio power plant. An expensive option, but it should improve sound quality as well as provide you with the correct voltage. They take input from 95 - ~270 Volts, and put out 120. Its $2k (new) for 600-700 watts output at 120V.
