Ted & Paul: Is it correct to assume that if we forget about capacitance and radiated/propagated noise on 1m Interconnects (and the +6dB gain), there is not a huge reason for why selecting the DS XLR over the RCA output?
The reason for asking is that my preamp is not fully balanced on its input and output stage and they advice using RCA for both.
The output contains a line driver Line Driver so it may be that I run my amps in single ended also, because I am a bit skeptic to the principle and quality of this line driver from a high end perspective. The remaining parts of the circuit is built with 24off discrete components.
I would expect the input to have a similar Line receiver (my guess is this one Line receiver).
