You could do much worse than a B&K amp (along the lines of ST1400 Series II @ 125w, Reference 4420 @ 200w) and Acurus RL11 remote-controlled preamp (one of Acurus' GOOD products -- forget about their amps though.) You'd probably still have some money leftover. The B&K amps are about the best available for the money used - they lack the harsh and nasty character that alot of SS amps in the sub $1000 price range display. They're just warm and smooth, and have a laid back and coherent soundstage. Don't let the "boutique brand" crowd upnose you away from B&K - you'll be eating their lunch until you spend quite a bit more money. Also, a Conrad Johnson Sonograph SA-250 is another great amp in this price range, perhaps even better than most B&Ks. Another smooth performer, with expanded clarity.
Hope this helps!
