I never had any problems with my bridge II card. If we had a storm and had a power outage, I had to reboot the dac and everything was fine. Ethernet was better than all the other dacs I auditioned and what my friends auditioned. I then moved to the airlens which I use i2s and the sq went up again. Traded the bridge ii card towards the airlens. Got a nice $800 i2s cable and I’m set. Other reviewers have stated the airlens makes the ds mk1 sound better which I agree with.
