Funny you should ask this, since one thing I remember well from one of the NYC H.E. shows was the VS room, where a pair of the 4JRs was sounding just okay with a large integrated, but the same speakers sounded incredible down the hall powered by the Moscode amp. I actually went back to the VS room and told them to go down the hall and hear their own speakers with the Moscode amp. Apparently, lots of showgoers had told them the same thing!
Anyway, the Moscode is a hybrid design with tube input stage and SS output stage, and even the old model I heard listed for $5K, so even used, it might be a stretch. That said, I am an Odyssey Stratos (HT3) owner myself, and can vouch for these wonderful amps, and Klaus Bunge who runs Odyssey Audio. I've had the amp about five years, and I have been pleased with it - smooth, detailed, powerful, dynamic and quiet.
Other amps I would look into in your price range would be the Vincent Audio SP-331 (also a hybrid), any of the Belles amps if they are in your price range, and the Butler hybrids, if you can find one used.
One thing I would do in your situation, focus on a two-channel amp. You'll get the biggest bang for your buck. Keep the B&K for the center and surrounds, since you have no complaints about the surround sonics.
