Schw006, I have had the following DACs in my own system, or own them and can highly recommend them. For reference they are quite a few R2R ladder DACs, which sonically are perfect for me.
$1,850 Denafrips Pontus II "12th Anniversary) DAC (R2R DAC)
$3,200 Musician Aquarius DAC (R2R DAC)
$5,500 Holo Audio May DAC "Kitsune KTE Edition" (R2R DAC)
$4,900 Denafrips Terminator II "12th Anniversary Edition" (R2R DAC)
$7,200 Denafrips Terminator Plus "12th Anniversary Edition (R2R DAC)
Others I have heard in systems I know, but never in my own....but can recommend:
$7,000 T+A DAC 200
$6,900 Lampizator Baltic (Think it was a 3)
For $5,000 I'd go with the Terminator II 12th no question. If you're good going to $7,000 then the Terminator Plus 12th, T+A DAC 200, and the Lampi Baltic.....would be a killer DAC shootout.
Best of luck to you
