Parasound JC1s.
Check out the Bel Canto Ref1000 monos, 500w into 8 ohms and very transparent and neutral.
Pass Labs
Bryston 4B-SST; built to professional standards; 20 year warranty.

Or you can save a ton of money withan ATI AT3002 or AT3004 if you want to biamp.

For $4k you can get a TRL D-225 dual mono amp. While it's rated at 225 watts per channel, it tests out at close to 300 watts. I've been using one for nearly a year now and it's driving my 8 ohm Spendor 1/2e speakers very nicely.
for that price i can't name any bad ones. it would be prudent to try a few with your loudspeakers.
