A Rotel 991 or 1080 would be on my short list. These are excellent SS amps. You can get the 991 for under 600 and the 1080 for about 700. A Parasound HCA 1500A will also do the job for under 600 bucks. All these amps are well designed and reliable but most importantly they offer excellent sound for the money. There's a 1500A on Agon right now.
If you had the money I'd recommend a hybrid like Blue Circle, AVA or Music Reference. Outstanding sound but not cheap.
