I have what I think of as Klipsch-cousins (Volti Razz). I was also looking for a new amp earlier this summer, though my goal was to have a low-powered/low heat alternative to my larger Class A tube amp. One of my solutions was a used Coincident Audio Dynamo 34 SE MK.ll. It has 8 very powerful watts, and is a SET amp that uses EL 34's instead the usual tubes such as a 300B or 2A3. I am pleasantly surprised at how much I enjoy it. I changed out the tubes to suit my taste, and it has met my goal of much lower heat in my listening room, without compromising the sound.
If used is acceptable, you might want to look into it...
