Used Speaker in the 15k range

i didn't see the op ask a question...  wish him/her good luck

Since you are looking to redo your whole system, why not take an holistic approach and go audition full systems? Some speakers works better with some amps and if you find a system with the sound you are looking for, then you can just buy that exact system. Going piece by piece is a lot of trial and error.

Good one. Very perspective. 

You can get Wilson Sasha's for $12K.  I would keep the PS Audio DAC (the jump up from that is going to be something like a dcs for $20K), but dump the BHK Amp - get a nice solid-state to drive those babies into bliss!  D'Agostino or Rowland.  (Rowland Model 7 monoblocks show up sometimes for $3500/pr).  This would be FUN. But if you want chamber music, Diana Krall and the like, not a good choice.  Then maybe some Mac lifestyle piece with some Focal/Magico/Sonus Faber and lots of whisky to forget your childhood fun rock memories and settle into that easy chair.

If you like lifelike timbre and musicality and dynamics with bass extension to 22K and a beautiful cabinet (made of 21 layers of wood) check out the Gamut RS7i (Ruby) up for sale right now. Extremely musical and possibly $15K would buy them. I know the seller and the care. Speaker retailed for $42K when new.
