USB if you want to

摘要

USB - the computer's Universal Serial Bus - has long been the poor relative of S/PDIF and FireWire when the time came to stream your hi-res digital audio from PC or Mac to an outboard DAC. However, with more outboard USB DACs accepting 96kHz/24-bit digital audio and employing an asynchronous connection, this is no longer the case. Asynchronous transfer allows the receiving device to regulate the flow of USB's packet data, without the need for complex buffering.
