-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.
