each DAC output should have it's own buffer, otherwise the design is incorrect
Hmm. I wouldn't necessarily use the word "incorrect." It really depends on the output topology. There's a transformer-output DAC where the xfmr is hard wired to both RCA and XLR. The manual suggests using only one output, not both. In a case like this, I would personally rather see a straight wire dual output rather than a relay selection (etc), assuming the manual offers a caveat on output structure.
