I hate leading people down this rabbit hole because these kinds of tweaks very personal and may or may not work for others. This is how I did it. Doing it this way instead of BNC-to-coax or coax-to-coax does sound better. To me, it's discernible enough where I am pretty sure I can pass a blind test after some practice. Using the pi2AES AES inputs results in a less grainy, less thin, less gritty, smoother, and more mellow "analog" sound. "Analog" meaning more similar to my TT source. Here is my chain. Too many headphones to show. (Ignore the Soncoz DAC - that's there for evaluation). YMMV.
