Which amp would be ideal?

I'd be tempted to try the Parasound JC-1. I'm kind of thinking you might want just a touch more power with those speakers (which are kind of inefficient). They are a bit analytical sounding, so something Class A I would suspect. A pair of Mc 2301's could be magical. What about a Pass XA100.5 or XA160.5?

I have a very similar setup: we use the same Esoteric and Cary Preamplifier and I use them with a Krell 250a and I'm very happy - GoldenEar Speakers -. Curiously I also listen to classic rock, like 70% of my music is classic rock and some jazz. One more idea: The Cary SLP03 really opened up when I changed the EH stock tubes, it was, in some ways, a different preamplifier, I used 4 vintage Haltron's. The bass with the Krell and Mod. Cary is great stuff indeed, always welcomed with the kind of music we like.
Sincerely hope this helps, good luck.
