Try a NAD C275 BEE. It's rated at 150 watts but can do much higher peaks for very brief periods; it drove my Magnepan 3.6's with no problems. It's smooth and even balanced with a sweet top and midrange and plenty of grunt for the bass. A good used C275 can be had for around $800.
Is it as good as my $8,000 Cary 500 monoblocks? No, but it is darn close.
