If you have the rack space and strength for it (56 lbs, 19+" deep), 4" clearance top and sides), look into a Denon PMA 2000 IVR. 80wpc into 8 ohms, but a full 160wpc into 4 ohms. This is one of those really high current amps, the type I've always found to sound uncommonly liquid and musical while keeping a tight grip on bass control and extension.
Lots of reviews at audioreview and elsewhere. Price is exactly what you're looking for. I think that its ability to deliver high current on demand would bring out the potential in your B&Ws.
As far as accessibility goes, there's gotta be at least one Denon dealer in every town. Even Crutchfield is a dealer. With the weight of that monster, their free shipping is attractive.
