How big is the room and what are you going to use for speakers?
Your budget is for an amp only, or are you looking at an integrated amp which will have a built-in preamp? What types of music do you listen to and how loud does it need to be?
All these factors influence which recomendations I'd make. There are a lot of choices in amps, but which one(s) would fit your listening preferences depends on these sort of considerations.
