So, installed Roon on my laptop. Found a WAV file. Plugged a cable in to the ID41. Went in to Roon settings to add the ID41 as an audio source. It found it immediately and I played the WAV. So signed up to Tidal. And connected that to Roon. Now playing my first album.

Everything just worked perfectly first time. Took about 10 minutes. And it sounds great. I'm extremely impressed.
