Yamaha A-S2100. It can sound as good as a class A amp but will barely get warm with high-efficiency speakers like your Devores.
Low-heat-output amp for Devore O/96
My Shindo amp/preamp combo sounds fantastic with these speakers, but during the sticky summer months here in N.C., my listening room gets uncomfortably warm, even with the central AC on. I've considered something like a First Watt JC2, but my understanding is these also put out lots of heat due to Class A operation. Any suggestions for a cool-running solid state amp that would sound good with the Devores?
