No thank goodness technology is doing away with the horribleness of USB.
I had all of that with my Pontus 2. Then once I got the Silent Angel streamer I could go direct I2S and not need a DDC. Sound was better and measurements were better.
Now I’ve optimized my network with FMC and LPSs for R26 via LAN and it is even better and measures better than direct I2S.
Here is a great educational review of how a flagship DDC via USB measures worse and subjectively sounds worse than a $150 direct streamer using only I2S. A DDC is pointless now when you have streamers with I2S.
A streamer is pointless when you have a really well implemented renderer via LAN in your DAC.
I need to disappoint you, internal "streamer" of R26 is connected with USB to its DAC.
