VirusKiller is correct in that I don't use MQA at all. I do play the occasional music file which makes the yellow light come on but other than that it's streamed music from Spotify and my own music collection.

Can I assume that as much as I like to have the most recent firmware, version 3.16 won't provide any benefits to me?

Thanks

System: DSP7200SE (upgraded) + RPI (PiCorePlayer) with Allo Digione running Squeezebox system.

Also various legacy 500 components - 557x2, 502, 508-20bit, 566-24bit plus too many other misc amps/speakers.
