2 Dec 2023 Update:
The Apple Music app on the Mac actually does provide volume control, but it isn't practically usable to connect via a USB to Coax bridge. The overall volume is way too high and you can only use the bottom 10% of the volume slider.
Here's the current setup:
1) Mac to SMSL PO100 Pro via USB cable.
2) SMSL PO100 Pro to Bluesound Node via Toslink cable.
3) Bluesound Node to Neumann KH120 II (KH 750 is still boxed up) via coaxial cable. This allows for easy Airplay use and direct playback from the Mac as well for Lossless playback. I don't love the touch volume control, but it works. I might get an IR remote.
New Edit: To be complete, if one didn't want a separate AirPlay solution for ease of use, connecting the speakers to a Mac along with software from

The below did not work. I assumed that I'd have volume control from the Mac, but that was not the case so the simple USB to Coax digital bridge of the AMB DAC wasn't sufficient, I'll need a digital volume control. Additionally, the AMB converts USB input to Toslink or Coaxial output. It does not output from the Toslink or Coaxial S/PDIF from a Toslink or Coaxial input. I was hoping to get a basic setup running with pieces I already had at home.

Thanks for the suggestion. I hadn't considered the Bluesound Node. If the USB input worked with a computer, then it would be ideal. I'll continue to look into it.
My desk is in the bedroom, so I decided that I will use the Neumann system for my computer which gives me a second high quality system (multichannel KEF system is in the works in the living room). We don't want a TV in the bedroom, so not using an AppleTV is ideal. I also want to have the speakers available for Airplay use for integration into a multichannel system. I think I have a plan as follows (my Mac doesn't have Airplay receiver so, I will try that when I get a new computer):
1) Mac to AMB gamma2 DAC via USB cable (Apple Lossless for dedicated listening).
2) AirPort Express to gamma2 via optical cable (AirPlay for general use).
3) Coaxial cable to KH750.
The AMB allows for easy switching between multiple inputs. It should work, but both of those devices are old and haven't been used in years, so I'll have to try it all and see if everything still works. If not, then I'll look at other setups.
Hello,
Did you consider the Bluesound Node which has been recommended somewhere in ASR? It has adjustable coaxial digital out. I recently bought it and use it since.
Best regards,
