@mofojo Well I just did a update and can't access my "audio" option (go figure) in settings in the Bluesound app. I believe it was at the last or next to the last setting you could choose. I am not positive if it actually disabled the clock in the Node but I had to tic that button to use a external DAC without glitches.
@OP I am very happy with having added a Pontus II and bypassing the Nodes DAC. I was surprized at the added detail, very happy with going to a stand alone!
Cheers.
