Amp for Vintage Heresy

Any push-pull decent tube amp. 

I am very happy with Heresy IIIs and I switch back in forth between a Pass XA-25 and a Dennis Had SEP tube amp. Both sound amazingly good.

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...

I run Heresy’s with a Tektron - using a pair of 45’s with a whopping 2wpc. Great pairing. Robin Wyatt is the local distributor and he swears by the Hereseys. 

Long experience with these. In college those Heresy’s really sang (and rocked!) with a Heathkit AA-151 EL84 tube integrated.  In today’s market, a Luxman SQ-N150 integrated would be ideal. EL84 tubes are comparatively cheap by power tube standards and with a relatively low heat output. Really lots of EL84 tube amps are out there as they were extremely common throughout the 60’s.
