The DAC is in real nice condition with only a mark on the top. See pictures. Functionality:

Needless to say, it works as it should (and then some) Color:

aluminium enclosure Technical Highlights:
The asynchronous USB input handles 24bit 192KHz sampling natively & this signal is communicated via I2S to the 24/192 DAC without any upsampling.
The DAC uses one of the legendary ESS Sabre DAC chips with all the proprietary technology of ESS - time domain jitter reduction, Hyperstream architecture
The result of this is a very detailed & dynamic sound with fabulous bass reproduction & airy highs.
The unbalanced 1.9V analogue outputs are directly DC coupled to the RCA connectors, no capacitors, no low pass filter or active components in the signal path.
Review:
AV Revolution: The John Kenny Ciunas DAC, at roughly $750, is a terrific sounding USB DAC that will fit into any space. It features a proprietary battery power scheme that works very well and, to my mind, clearly gives it an edge over similarly priced products.
