Full Review: http://www.head-fi.org/t/767950/nuprime-udsd-usb-dac-review     Great DAC for <$200.  Really could not ask for a better sound at this price and the portability is a great plug.  Quality RCA jacks make use that much nicer.   The quality of the sound from this unit may make you think twice about spending 2x-3x on a better DAC.
