$500 USB cable

Perhaps we should understand what is happening to fully understand insanity of expensive USB  cables.  In asynchronous USB, computer transfers the data in frames at about 1kHz rate.  USB DAC places the data in the buffer and responds with under/over buffer signal causing less or more data in the next frame.  This data is clocked into D/A converter with internal DAC clock that is independent of the transfer or computer.  The only thing that can remotely affect the sound is noise injected/radiated by the cable.

Is it just  me, or does @audioman58 write like William Burroughs?

toddverrone,
William Burroughs? LOL
...never seen him writing too much parasite phrases "i will say"

as fate would have it the same arguments can be applied to digital cables, both metal conductors and fiber optic cable TOSlink. Yet, in the case of digital cables there are obvious differenes in sound quality depending on the cable type and manufacturer. Consequently I'm not ready to buy into the similar arguments for USB cable, either.
