官方稱ASIO無增進音質效果且有可能降低播放效能:

Please note that this component is meant for systems where ASIO is the only available output method. It is highly recommended to use the default output modes instead of ASIO. Contrary to popular "audiophile" claims, there are NO benefits from using ASIO as far as music playback quality is concerned, while bugs in ASIO drivers may severely degrade the performance.
