I drive a pair of Magnepan 1.7 loudspeakers with a Rotel RB-991 solid-state amplifier producing 200 watts/channel. They sound great! This amplifier can be found secondhand for around $700. Alternatively, the current replacement model, the RC-1582 Mk II, for $1500 new in the box.
I also have a pair of Dynaco MK III monoblocks each producing 60 watts/RMS. They provide a warm vacuum tube 'sound.' If you can solder and have a few evenings free you can build a pair of these kits produced by www.DynaKitParts.com. These are the real deal, but you have to assemble them. They cost $550 each, slightly over your $1000 budget, but at $1100 well worth the effort.
