How about a used Aragon 2007? That would be in your price range. Very good amp. My friend has one, and it's been reliable and sounds excellent. I've never heard it with Def Techs, so I can't comment there, but it does possess a nice, smooth sound on music, and on video, it can provide some big-time slam.
Oh, and BTW, anyone who says Def Techs aren't good for music isn't listening closely enough. I have the STSs, and they beat a pair of Vandy 3As and Von Schweikert VR-4 HSEs in my second system.
