In Reply to: Why USB? posted by ketchup on October 18, 2004 at 16:39:51:
First, outboard power supplies for the DAC function. USB allows me to get the digital stream out of the PC without using any soundcard that relies on the PC's power supply. These were never designed with audio in mind. Also, the cost of the connections are low given its availability on most any new digital device.Second, USB is a syncronized data stream. Unlike SPDIF, it uses an internal clocking mechanism. There was an attempt years ago by Audio Alchemy to get the industry to use I2S (I squared S), which employed a separate clock signal to keep the SPDIF data stream locked. Didn't really happen.
I'm sure there may proponents and detractors here but that's my logic and I like the results.
