Toslink vs. RCA


In virtually every review of DACs and jitter reduction devices, RCA seems to be better than TOSLINK for the transmission of S/PDIF. This seems strange to me considering that a whole host of nasties like EMI and transmission line effects can be eliminated with optical transmission. Does anyone know why RCA is better?

Talk about timely topics. I spent a fair amount of time last weekend searching through Audiogon's archives for information on AT&T ST. There were lots of opinions on whether Toslink, coax, AES/EBU and AT&T ST was the best digital connection. The final concensus seemed to be that AES/EBU is best. That requires one point of clarification: the very few that had any direct experience with AT&T ST thought it was a strong contender, maybe even better than AES/EBU.

To that end I'm interested in giving ST a try. The problem is finding a quality cable. None of the major cable companies seem to support even the more widely used Toslink, much less something as esoteric as ST. There is nothing for sale on Audiogon, either. Can anyone suggest a source?

BTW, this will be used between a CAL Alpha/Delta combo that is currently tied together with an Illumanti D-60. Thanks again!
6chac, what you wrote parallels other's experiences I read. The REAL question is "Where can I buy a decent AT&T ST cable?" For instance, where did you buy yours? Any particular info I need for ordering? TIA.
Called Steve at Great Northern Sound this morning. Found him to be very friendly and helpful. He has three different AT&T ST cables available. The first two were out of my price range ($400 & $900 as I recall). The third was the 3 meter Wadia and the price quoted was ~$60 including shipping. I opted for it.

Thanks again, 6chac.
