I lived in the UK for 3 years, and took all my US spec equipment. You can purchase transformers to step down the voltage to 110v, but it will still be 50hz power. That's only an issue for turntables or tape decks that have a motor that's synchornized to the frequency of the power (ie, they will run at the wrong speed.) It should not damage your equipment, but make sure you use a transformer of sufficient size, so as not to overload it...I used a 2Kw one.
The most elegant solution would be to buy a power regenerator like the PS Audio 300. (I have one and wouldn't part with it.) The P300 can be internally rewired to accept 220v, but it will output 110v, at whatever frequency you select. Essentially, that means you'd be using it as a very high quality step down transformer..one that also cleans up all the garbage and significantly improves the sound. The only catch is you'll need to get a power cable for the P300 with a European style plug, but that's not that difficult.
