I’m trying to connect Up2Stream Pro V3 receiver to my Amp. Okay, I have linear 3.5mm output but this solution doesn’t look good to me. I’d like to use: 1) bluethooth (the Up2Stream should transmit music from board to external power amplifier via bluetooth 5.0). 2) use digital SPDIF but again, this will require wires, I’d like to use a wireless connection. Is it possible?
