Your description and speaker screams a great match for Atma-Sphere. The current mk III versions are best. The MA1 mkIII would be more than powerful enough for your speakers, and perhaps even the M60s would be a good match and save you money/energy/heat. Mate w/balanced preamp to get the most out of the design.
My Dehavilland Aries 845G would also be a good fit. They are SET, but more powerful than most SET, and mate well w/wide range of speakers. A tad sweeter mids than the Atmas, but still not euphonic like many tube amps. The newer model with the GM70 tube is even higher power if you don't mind a less common tube.
The Lamms are also a good choice.
Cheers,
Spencer
