how to run a 230 volt line from my panel??

I am getting a piece of equipment from europe that is set for 230v- I called the manufacturer and they said it can not be rewired to 110 I should simply run a 230 line= i already have 12 gauge wire ran to the stereo room- Is it just a matter of getting a 20 amp 230v breaker for my elec. panel-
Can i use the outlets I have now and a USA type power cord or what do I need to do?- thanks
