Kenwood KR5150 40wpc Kinda tube like, very warm. That and its little brother KR-2120 which is also nice and low watt (20)
Pioneer SX-440 15wpc, this one I have not been able to spend a lot of time with yet, but my initial thought was very nice sound. I need to re-lamp it soon.
did you mean SX-450? I'll vouch for that
