Wadia 321 question

I am considering this d to a and would like to hear from anyone who has used or listened to this converter.
I just bought one new off Agon for $1,000, a great deal. I compared it to the Bel Canto Dac 3 and NAD M51. It bested the Bel Canto in total output, finesse, and certainly bass. The NAD was really close but I preferred the warmer sound of the Wadia on my higher efficiency speakers.
