Anybody running a NAD M32 without BluOS module?

So I’m debating a potential purchase, and the NAD M32 has had my attention for a while. Does anybody run it without the BluOS module, just through the USB input? Is there any reason not to – other than MQA? My understanding is that it won’t do any MQA decoding or rendering via its regular digital inputs, is that correct?

I was using a 390 via the usb input, Roon sees it fine couldn’t think of a reason to buy the BluOS card
