Getting lossless Apple Music to my dac

I got sick of Amazon raising prices, so I tried Apple Music and actually think it sounds better. But for now, that's just via headphones or in the car. My question is how to get lossless from either a pc laptop or an ipad to the dac in my McIntosh MA5300. From what I've read, something like a Bluesound Node would only work via Airplay 2 from the ipad, which does not handle lossless. If I go from a usb A out on my laptop to usb B in on the McIntosh, I still don't know if the pc is sending it out as lossless or not. Any input from someone actually trying to get Apple Music to work lossless with an external dac, assuming I do not have a mac computer?
