Yes, well, there are a gazillion music-computer tools that use firewire, and another gazillion that use usb.
The firewire kind is used by the pros.
The usb kind is used by the folks that shop at radio shack.
The reason, plain and simple, is that firewire piggybacks well while usb does it very poorly; firewire impacts the cpu far less than usb; usb can freeze your computer, firewire can basically never do that.
So why is usb more popular than firewire? Probably because one was promoted by Apple and the other by Microsoft.
I'm simply going to say that of all the serial interfaces, usb is among the most compromised and DEFINITELY not the one you want to use with an instrument that is simultaneously expensive, high-performance and meant to be long lasting.
I don't mean to rain on dbaudiolabs parade, but if there are people out there that are just getting started and wondering what is what, you can do well by simply avoiding usb for anything expensive, high-performance or long-lasting.
IF there was going to be a single input to your dac, it should be coaxial or optical. It should not be firewire for the reasons listed in the post above, although if it were, it might possibly be OK; it should not be usb, at the very least, for the reasons I have given here.
I am under the impression that there are audiophile reasons as well for not relying on usb, such as those in this article,

which basically states, among other things, that you have to think long and hard about how you are going to connect your computer to that USB cable.
A properly designed DAC (and you can certainly find them for hundreds of dollars less than the one being reviewed above) will not force you to do any such thinking about what your computer is doing on the other side of that optical/coax digital input cable; in fact, it might not even require you to turn on a computer at all. :)
