Firewire could be very neat: if I understand correctly, it also eliminates jitter because the timing information is actually encoded in the signal rather than being deduced from the signal timing. But I suspect that Bryston will want to wait until the industry as a whole decides on a standard for high-bandwidth digital audio, and that's not going to happen any time soon because of perceived copy-protection issues. Even when it does, Firewire may not be the choice.
