According to Dan Lavry, FireWire is too expensive to develop for,
although with his prices I don't see how it would be much different.
Sorry to talk near-audiophile language here, but this list combines
a unique collection of software engineers and FireWire designers
(Metric Halo and maybe even MOTU and RME). I have been trying to
identify the ultimate audio interface for Mac, along with the
correct software to drive it. I am up to the task of developing
the software, and even drivers if need be, but the research on the
possibilities for hardware is still ongoing.
I would imagine it has a lot to do with your requirements for
latency. If you need low latency, it's hard to beat stuff clocked
within the computer itself, but that will have its own limitations.
Funny that you should mention Lavry, because I use one of his Lavry
Blacks for most of my monitoring of serious work. If it was USB I
can't see how it would be much different, because Lavry's reclocking
is so comprehensive that it incurs enormous latency. I cannot track
through this unit (even on 'wide' clock acceptance, oddly enough!)
but I haven't had any complaints about its audiophile qualities- when
clocking it to 'crystal', the sound is seriously unjittery.
Of course, that IS a local, crystal clock- hence the name. So I
guess your point stands :)
But again- I absolutely cannot track through the amount of latency
this DAC incurs, on any setting. It's a playback/mixing/mastering DAC.
