Roon will allow you to decode MQA, unfortunately, you have to pay for the service.
JRiver seems to not be wanting to do so.
If I recall, Bluesound does the first unfolding, but not the full unfolding in the Node.
To add to what others have opined, MQA is a lossy format that you have to pay for, so why bother? I just moved to Qobuz and listen to high rez lossless.
