Asynchronous USB essentially turns the computer into a slave device as opposed to adaptive USB which does the opposite. Thus, an asynchronous USB DAC has total control over the timing of the audio. One very important feature of asynchronous USB mode is bidirectional communication between the computer and the DAC. The computer sends audio and the DAC sends commands or instructions for the computer to follow. For example the computer's clock becomes less accurate over a given period of time and can send too much data too quickly and fill up the buffer. Asynchronous DACs will instruct the computer to slow down, thus avoiding any negative effects of a full, or empty, buffer which can manifest itself into audible dropouts and pops or clicks. According to Wavelength Audio the tail is no longer wagging the dog when using asynchronous USB mode. Plus all of this is done without additional device drivers or software installation.

Kanskje ikke så merkelig eller overraskende at asynkron overføring er vinneren..

Lekre produkter, settet fra dCS skulle jeg gjerne hatt. Vet noen prisen på Ayre QB-9?


Hvordan er egentlig FireWire sammenliknet med asynkron USB?
Tenker litt på å få prøvd en Weiss Minerva (eller DAC2 og spare masse penger..), som begge bruker FireWire, samt en dCS Puccini U-Clock.
