So the streaming service that I use for this is Pristine Classical. These are historic recordings, almost all in mono, frequently pre WW II. The digital restoration is amazing, but I find that AirPlay or Bluetooth is enough fidelity for these as the source is inherently limited. Unfortunately my streamers are incompatible with this particular boutique service.
I actually am impressed with AirPlay for conventional CD replay, as per the previous poster. Google Chrome is better. Bluetooth, not so much
