Can anyone suggest a good 2-channel amp for $1500

Conquered home theater, but want to set up a decent semi-reference 2 channel system. I'm welcoming suggestions for a decent 2-channel amp putting out around 100WPC RMS that would go for ~$1500 US or less (preferrably less). I am considering tube amps, but want to know what those advantages are over a solid state amp.

Thanks...
