Based on the recent barrage of pro asynchronous USB and anti just about every other digital audio transfer mode (e.g. S/PDIF, AES/EBU, BNC, optical, etc.) how is it that the Bricasti M1 DAC and the Weiss DAC202 are still listed as class A+ in Stereophile's April 2012 Recommended Components? Could someone please clarify because I am very, very confused. In other words, are there other digital audio transfer modes which are "audiophile" quality besides asynchronous USB? And if so, why?
