Just received my DAC+ADC Pro which I intended to use for streaming input from turntable into LMS.
For testing I've plugged in audio from my macbook pro, and though I usually can't tell the difference between good hifi stereo equipment and a cheap one, I must say that I can truly tell the difference between Spotify audio coming in through DAC+ADC Pro vs streamed via Airplay or Spotify connect.
And to be honest well the quality is kind of crap. Maybe I was expecting too much of 60 euro device? It's like I would be listening to some old car stereo, some "wobbling" etc.
Or is my setup/settings broken? using it on a rpi 3 b+ with raspbian
