I've been using this DAC for a few months now and it's been amazing. I use it mainly as a DAC for my CD transport, via coaxial and optical audio connections. I purchased it because I wanted sound options depending on what I'm listening to on my CD player. I switch from the CD players built in DAC to this. For $89 it delivers a nice clean, precise sound with a wide sound stage and good bass punch but not over bearing. I'm not an audiophile, but at this price point you're getting a high end ESS Sabre chip that's in much more expensive DACS. You can't go wrong, so I highly recommend it.
