I doubt an American dealer can order you a 220v system.
Shouldn't be a problem. Get something like this, but never, ever try to juice your new component with 220v or you'll fry it. Too bad the US is about the only country to use 110 volt while the rest of civilization used 220.

FYI - Most small appliances can be used with transformers. Some appliances that are not recommended for use with transformers for overseas use are the following: microwave ovens, irons, radio alarm clocks, vacuum cleaners, electric cooking ranges, televisions, video recorders, washers, dryers, refrigerators, & dishwashers.
