I’m using USB between my BDP-3 and Esoteric K-05XD. Everytime I switch input I have to switch off the streamer and then switch on again. The system is Linux based and with USB is important to be turned on AFTER the DAC. According to Bryston this will be avoided with AES/S/PDIF. ”SPDIF doesn't rely on drivers and proper boot sequence like USB does”. I will try a SPDIF cable instead of my current USB connection to avoid the hassle.
