Been having a good listen this morning, it's good, not great. A bit harsh and recessed compared to my touch through Mdac. The volume level is quite different from the mdac but that might be because I'm using the balanced output on the mdac. I've set the pcm level to 86 and the other 2 are at 100 in alsamixer. How do I check the output voltage is 2V? I'll leave it running all day and hopefully it'll improve.
