I'm kind of a fiber guy myself. I've been using fiber for ADAT transfers and haven't had a single glitch. Absolutely NO electrical or RF interference possible. The only thing with coax to watch is the cable length. I forget what the maximum length is, but it's not REAL long. [like definitely under 20 feet, and probably under 10] Fiber can be much longer than the coax for S/PDIF. Great if you have your computer in a different room. For 6 feet of distance, I don't think you'll notice much difference. mrmatta, wouldn't you HAVE to clock to the Rosetta, since it's the input device? You'd get clicks otherwise, wouldn't you? ------------------ LW
