After much research I went with the NAD M51. They can be had for under $800. USD. Retailed for about 2K. They are compared frequently with the Bryston B2 Dac. Which still sells for 3 times what the M51 sells for. I am very happy with it and noticed an immediate difference in Clarity and Detail from my $500 Aune tube Dac.
Worth the read IMO
