Agear,
As I understand it, USB asynch mode is one of several mmodes of operation for USB. It is intended to assure bandwidth,which is needed for high res audio to stream fast enough to keep up with playback. It also allows the "peripheral"device to be in control. You want that to be a DAC of high quality which includes an accurate clock to keep jitter minimal. In lieu of that, computer/server assumes that responsibility and other modes not as well suited for audio sound quality may come into play.
