Returning to the original title of this thread:
I finally figured out a way to diagnose my very occasional dropouts. I listened to the audio from the external DAC and noted dropout times while simultaneously digitizing the audio output directly from the Node 2i with an external USB Audio Interface and Audacity. Then listening to the digitized recording, I was able to check the noted times for dropouts. There were none. Since I heard only two dropouts during this 45-minute session, it's not an exhaustive test, but it strongly implicates the digital-coax connection between Node 2i and DAC, as opposed to the Internet feed to the Node 2i itself. I will next try an optical interconnect, since the Node 2i does not offer a USB output. At a maximum of 24 bits by 96 kHz (set into the Qobuz login on the Node 2i), a TOSLINK cable really should have enough bandwidth... -- Clark2
