Based on your requirement, NAD Masters M33 or M66. The Naim lacks phono inpot.
While not 1 sleek box, I would spend that $15k budget on an Accuphase E-280 (add phono card or Schitt Skoll) + HiFi Rose RS-150b. If you want fully balanced, step up to Accuphase E-4000. Again, my money, but I would strongly consider grey market Accuphase.
