So, can I rip a MQA-CD to a hard drive with EAC and play back in full MQA through my Lumin D2 ?
Yes, you can use Lumin app to play it back with full MQA decoding.
For Roon playback (instead of Lumin app), there is an open ticket for MQA CD at the time of this post.
Has this been updated? Can you now play a ripped MQA CD in full MQA with ROON though the D2?
