"Even the worst Wal-Mart Special is better than most computer drives due to interference from other components and feedback from power supplies, fans, computer monitors and the like."
What complete nonsense. A computer is capable of reading hundreds of megabytes of data from a CD-ROM with not a single bit error, yet it cannot read a music CD ?
Also, since USB is a packetized protocol, a USB DAC must perform buffering and reclocking of the data before presenting it to the DAC, and so if the USB DAC master clock is of sufficient quality jitter is almost entirely removed.
Technically a USB DAC is capable of exactly the same performance as any one or two-box CD player.
