I apologize in advance if this is the wrong place to pose this question. I am new to the site and considering using my PC as a source for a Benchmark DAC as well as other sources (DVD player and cable box). This thread and others on this site seem to strongly infer that a configuration using Lynx Studio AES16 PCI card connected to the DAC is substantially superior to a USB connection to the DAC (presumably without the Lynx Studio AES16 PCI card). Is that a correct conclusion? If that is correct, for those that follow this course is there any reason to be concerned about DAC USB capability?
