Right now listening to my k1ks driven by the Cary 300 sei. Eddie from Ohio on the AA Prima. Nice tight bass, plenty of detail, lucious vocals, good hf extension. 3 inputs and its an integrated of course. Can also use it w/headphone jack for Senns if you have them, too. Highly recommended at its used price of around $2k. I also had good luck with a Cary 2a3 integrated, but its bigger size and much higher heat output (4 power tubes and dual tube rectifiers) it didn't work as well in my office.
