Well, if you are so sure there are no differences, then why don't you conduct the test yourself?
Because whenever a person says "I doubt that it will be heard" and does a test with that outcome, they will be criticized for not trying hard enough because after all they said "I doubt that it will be heard" .
There is no evidence that asynchronous DACs were ever designed to solve an audible problem.
It is known for sure that even fairly inexpensive non-asynchronous USB DACs are sonically transparent and will pass a straight wire bypass test.
Here's a <$30 USB ADC/DAC pair that passes blind listening tests: Behringer UCA 202. Prove me wrong!
Here is the frequency response and dynamic range test data from a USB DAC that cost me $6.95. Doesn't sound too bad:
Frequency response (from 40 Hz to 15 kHz), dB: +0.19, -0.66 Good
Noise level, dB (A): -74.0 Average
Dynamic range, dB (A): 74.4 Average
THD, %: 0.050 Good
It's about 20 dB worse than the UCA 202 - I think it might have some audible artifacts, just barely.
