Bought this open box. Not sure why I didn't think of this before - guess I thought the audio out from my ECHO Dot was doing justice to feed my 80's era upper quality sound system. I always thought something was missing in the sound and found great improvement with a proper DAC/Network device. The setup was out-of-the-box stupid easy. It connected to my network and media on attached NAS with no drama. It appears on my iOS devices as a target to send music. Great build quality and brought my streaming to par with quality of the sound system to which it is connected. Very pleased.
If you're sitting at the sidelines like in was undecided which route I was going to go. wait no longer. Easy to set up and the sound quality is superb! Well worth the money. Makes me want to throw rocks at my FM tuner
