Agree on Classe (esp.) & Krell, both in heavyweight version (not discount amper. / 80 W, etc). In another vein, I spent a happy 2 yrs powering my Calipers with EAR 519 (albeit with upgraded capac/rs in the power supply). Phill is right about cabling: use clear and FAST and with monos, SHORT!
Forgot about an amp that should work very well with the Calipers (or any other non-hybrid Apogee). Check out the Innersound amp. This was designed to power their own esl's. Unlimited headroom, loads of current and voltage. All the things that your speakers need. Supposed to sound quite musical, to boot. Innersound has a site with info about their products.
absolutely KRELL KSA 100 MkII with MIT MH 770 spectral ref. Mk II spk cable. Bye
