Matt - with all due respect I think you may be referring to the XMOS USB input receiver chip, which is used in many high end DACs including the Bricasti M1. CMOS stands for a Complementary Metal–Oxide–Semiconductor, a technology for constructing integrated circuits but not related to USB input circuitry.
That is highly amusing. Outing our technical ignorance. We all know just enough to be dangerous. That reality still does not temper our baseline of arrogance and fountain of quick opinions.....
