I would go with a Rega Brio 3 int. amp. and build from there. I auditioned plenty of int. amps and the Brio 3 was the best for the money, and a lot of audiophile magazines are saying the same thing. I have built an excellent budget system around the Rega (some items for sale) with a Squeezebox, a Rotel tuner (up for sale now that I have the Squeezebox) and some amazing Mordaunt Short vintage speakers (also for sale) and it sounds pretty awesome for the most part.
I hope that helps.
