I saw a digi coax > firewire a couple days back running AD2K+ > Laptop. I asked the taper and he said a friend made the cable. He loves the AD2K+ (for obvious reasons), but really wanted to do 24/96. I don't have firewire on my laptop and my pre doesn't have USB out...BUT, if I could do coax > USB, I could run 24-bit w/ the laptop > DVD-Audio.
