Mac (Audirvana Plus 3) to Muso - Hi-Res?

Hi everyone, first of all, thanks to all of you for your various posts. I've done loads of research over the past year or so and that has led me to buy a Muso and Muso Qb (with my eye firmly on an Atom for when we finish the lounge).

One thing I haven't been able to piece together from the various  threads related to this subject - is it possible to stream hi-res audio (24bit 192khz) wirelessly to a Muso?

I have tried streaming Tidal MQAs using my Mac, but Airplay limits it to 44.1khz. So then I tried downloading the trial version of Audirvana Plus 3, to use as if it were a music server via UPnP. When playing Ella Fitzgerald's Sings Sweet Songs For Swingers, Audirvana showed "DAC 24/96kz" and on the right "MQA 24/192hz Stereo". Does that mean it is working?It sounds great but I'm sceptical about how much more detail is in MQA in any event. Is it not just a compressed file by another name?

Finally, the specifications of the Muso on the Naim site make me think that if streaming via wifi, it can't accept more than 48khz anyway - "All formats to 48kHz maximum over wireless network.". Though that may be outdated and have been fixed with new firmware. Should I just be happy enough with 44.1khz/16bit? If the bitrate is higher than 320, does that make any difference? e.g. my old ripped lossless CD music is 44.1/16 but have 1000+ bitrates.

Yours in thanks and confusion
