Hiya Srajan,
I second Fred's heads-up on I²S. I'm curious to see how you get on with your players. It was somewhat disappointing to learn that matching sockets don't predict successful handshakes. You mentioned a miss between your USB bridge and the Aqua DAC's Ethernet port. How the hell is a consumer supposed to figure this stuff out? It seems like a classic hit and miss proposition; except that it'll be costly if one misjudges.

Good point, John. It would seem to require contacting both manufacturers of whatever pairing is under consideration to have them confirm matched or mismatched wiring. I admit to being baffled myself why there have to be multiple ways to wire up an RJ45 socket for this purpose. Hopefully Métronome's HDMI version will play ball with how Denafrips do theirs. But this is far from the only example for how high-end audio lacks standardization. Pro audio just wouldn't work if they played it as loose as our sector does…
