the number of dacs in a cd player for balanced is purely to reproduce the same signal inverted for the noise reduction.
This may lower the noise floor, but does not enhance the dac conversion, it's simply duplicity of effort to get balanced (not a chain of dac chips working in tandem)
yes xlr is better for longer lengths
but one can get great results with rca
my preamp takes all xlr inouts
but I use single ended with cheater plugs on almost all pieces with good results
