Just curious if anyone has tried streaming Bluetooth audio to a USB Bluetooth receiver through the QU-Drive port? Not sure if it’s possible but would free up all the other channels on the board for other inputs.
As an alternative thought, I use an Apple Airport Express and run a TOSlink cable through to a small spare DAC I have.
Airplay is ALAC (Apple’s compressed lossless audio), which from my own listening experiences sounds better than Bluetooth audio. Of course everyone’s mileage varies.
