I'm happy. I just like to know where I stand relative to the spec. |

For audio playback, USB is now just as good as Firewire thanks to the |
18 |
inception of the asynchronous (as opposed to synchronous or adaptive) |
19 |
USB DAC. In an asynchronous implementation, the clock is in the DAC |
20 |
itself and operates independently of the computer. However, if |
21 |
Firewire has lower latency I can see how it would be better than USB |
22 |
for audio recoding and production. |
