-I've seen these on some equipment, is there consensus (audiophiles, consensus? HA!) on BNC vs. RCA for S/PDIF?-
The simple fact is that compliance with the consumer spec. mandates RCA, but this will *always* sound worse, unless the external DAC is completely insensitive to incoming jitter (e.g. Benchmark DAC1) since the RCA can never be a true 75R. AES / EBU allows XLR's, which are nominally 110R, but discontinuous impedance characteristics, which makes them pretty poor too (but not as bad as RCA). The reflections introduced will add significant jitter, for most consumer grade units the jitter on SPDIF with an RCA is likely to be in the order of 500-1000ns, with a really good one being maybe 10ns. You wan't picoseconds here...the sonic results usually largely depend on how well engineered the DAC is. Even with a BNC it's hard to get it right, but at least it's not intentionally handicapped from the outset. Andy. -- Andrew L.
