Quick question: I'm using a high-quality BNC coax to connect the 502DAC to my Soekris dac1541. I didn't realize I could do AES, how would I do it and would it matter? I've not tried the 502DAC as a DAC, as I had the dac1541 already and I have a thing for R2R DACs But for someone starting to build a stand-alone system, the 502DAC is a great one-hat solution, for sure. When I have a bit more time, I'll assemble a full bill of materials and assembly instructions (what I can recall, that is) for my work system. It was a lot of fun to put together hardware and software, and the 502DAC has performed flawlessly all along, tolerating my poor manual coordination and lack of proper anti-static precautions.
