What does a USB memory stick have to do with USB audio?andyjm said:As I mentioned, the best place to have the clock is right next to the D2A chip. Putting the same clock somewhere else will be worse.
Slaving a DAC to a clock generated further upstream is a legacy of a time when flow control and async digital data transfer was expensive. Nowdays chipsets to do this cost pennies. How much did that last USB memory stick cost you bought?
Not necessarily. It just shifts the dependency to the source.andyjm said:
If you choose to buy a DAC that relies upon a synchronous approach, then of course you are dependent on the quality of the input clock, but it will never have the same jitter performance as a DAC wth a local clock.
