Where did you find out that adaptive USB doesn't perform as well as async? Have you got any technical results from any test you carried out to back up that claim? So far all that can be found on the net about the alleged superiority of async are the claims made by the original person who did the initial work on the software. Actual a-B testing by many, including quite a few DAC manufacturers, have not substantiated the claim that async is better. What does better mean anyhow? <br />
Wake up and smell the coffee I say.
