I'm trying to determine the best interface between my computer and an external DAC (looking at new Bifrost). Trying to avoid going with a typical USB connection and would prefer S/PDIF. Is there a sound quality difference between using the motherboard's optical port and going with something like the M2Tech hiFace or even the fancier hiFace Evo? I understand the M2Tech is USB but for their price I though it might offer an advantage over using the motherboards onboard optical out.
Thanks!
