This is the original firmware thread when the SE and .2 speakers were upgraded to render MQA.

To clarify my above comments, re: 5200SE vs 7200.2, I would not include the 5200.2 in that comparison. Factory 5200SE with the clamp rings are the only flavour of 5200 I’ve ever gelled with I’ve owned 5200.2 and they’re the only Meridian speaker I didn’t get on with - I found them a bit “meh/flat”, which doesn’t mean they’re not a great speaker, but the factory 5200SE is a very big step-up, and 7200.2 are massively better, all to my ears, YMMV, etc.
