Compact, capable, and easy to use, it could be all the DAC you need.

Excellent DAC/ AMP combo. Sounds really good. Accepts 1/4 and XLR connections, used both a various times with great results. NO box or instructions so you must be able to connect on your own, pretty easy though. Upgraded USB Cable (Audioquest) for connection from computer to unit, provided The only other connection is power from unit to outlet with supplied power cable. Just listened to my phone through RCA inputs and it sounded great. Usually listen via USB connection on my computer so it was good to know it works well both ways. Prefer computer setup. Great little system. Looks better in person, like me.
