Speakers for Cayin KT-88

Hi there guys, I sold my Polk LSI 15 yesterday, now my second system is without speakers.

I mostly listen jazz, classic rock, and vocals,

I like the sound with details but not to harsh that doesn't aloud you to have long listening sessions,

I think the cayin KT 88 its a great amp, i would really appreciate if you can advice me of anything currently on audiogone for sale, my budget for used or new, 1500 or so.

Thanks a lot.
