Hi,i'm looking for the cheapest and best way to get data out of a G5 and into a Benchmark DAC1. I currently have the thing hooked up via optical, but the optical-in on the dac has been somewhat hurt by involuntary cable-walking foot contact. My assumption would be that the best way, jitter, ground, etc. wise would be to hook things up through an AES interface, but i can't find anything reasonably priced, or specc'ed (i _don't_ need 16 digital outs and the kitchen sink).
is there anything i'm missing, or should i just drop the angst, get a cheap usb - spdif interface and call it a day ?

Jacques is right. See if you can position the Benchmark near the G5. On the flip side you don't want it so close you'll pick up computer processor noise. Optical is the best way - just get that cable off the floor!

No, the Benchman DAC1 is well built, which means it doesn't use the raw clock as extracted from the digital stream (would it be AES/EBU or optical) but recreates a new low-jitter clock based onto the raw clock (to be read by techies only: use of a low-pass filtered PLL, a low jitter VCC, and a FIFO as elastic data store). So no jitter concern. Few ground concern either, as the AES/EBU standard requires a low capacitance transformer .
As for the optical output of the G5, it solves all remaining problems in these matters. A low cost optical conduit (plastic) will do the job fine between the G5 and the DAC1. Useless to have diamond fiber optics and other "high end" optical interconnect : the well defined level of the G5 optical output and the reclocking in the DAC1 make them work fine on any interconnect, (as it should be on any "high-end" equipment...).I do think that the best (in terms of quality and ease of use) and less expensive solution would be to have the DAC1 optical input fixed .
