I have the same speakers and am using them in a 14X24 room. I used to use 8 watt SET amps and those worked great, but, per the previous suggestion, I'd choose a different amp for rock (I don't listen to much). Currently using a Modwright KWA 150 which is a great match, but probably not what you're looking for as it's not integrated and out of your pricepoint. Integrates at the $1K point I'd consider worth auditioning that would excel in rock and still sound great in your other preferred genres: Portal Panache, Rega Mira III, Audio Refinement, Creek 5350SE.
Integrated tube amp for Coincident Super Eclipse
Before I sell alot of my gear (recent job loss) I am wondering what integrated tube amp would be a great match for my Coincident Super Eclipse llls? What about SET amps? For whatever reason, I am thinking of a Cayin A88T as a good match.... any suggestions? I listen to folk, rock and jazz and my room is 12'x25'.
