Latest version of the NOS DevilSound dac - see link for changes and description of the dac. As simple as it gets - 6 foot USB cable to Dac and short interconnect to Eichmann RCA's - uses AD1851 dac. Very musical sounding piece with stellar reviews, works flawlessly with Raspberry Pi as well. Reason for selling - investigating other options for the Pi- shipping at cost
