I've used this DAC for about a year; it replaced a Lavry DA10 and Benchmark DAC1. It sounds great and is very well built.
Inputs: USB (which I used exclusively), optical, RCA/BNC, and AES/EBU
Outputs: balanced and unbalanced
Unfortunately, it has some cosmetic damage:
1. Small nick on top of face plate (right above the "Storm" text in the picture)
2. One of the 12 hex screws holding the top plate is missing.
Originally cost was $600. Asking
$OLD shipped OBO.
