Buying Audio in EUR and bringing it to the US for resale

I have the opportunity to pick up some high end UK gear ( 5k-10k resale range )  does the fact that it is 220v going to heavily impact selling price back in the states? I wasn't aware of the 50/60 frequency issue, and it seems that people who rave about $3000 cables are the same type that might have a problem with the voltage at a slightly off frequency.
