How so? I do not believe audiophiles who spend extra money on an ethernet cable necessarily feel bad about doing so. I would actually suspect that they feel good about it.
In addition, my response was to the argument about data transmission correcting for error due to a bad cable, and that the argument still stands regarding possible noise inserted after the DAC. Like I said before, I believe that's highly unlikely, since noise after the DAC means that there's noise on the MB and there are plenty of more sensitive circuits on the MB susceptible to noise, but to summarily dismiss that theory (or via test results from 20 subjects who were primed anyways) is just wrong.
