As long as source and the input are not ground related capacitance between wire and shield has no effect, but capacitance between wires still exists. Dielectric with lower dielectric constant will reduce capacitance between wires. Signal wires in XLR are usually twisted - a very effective way of reducing electrical noise pickup, but nothing is 100%. Better cables often have better shields protecting better.
Is a balanced XLR cable inherently less critical than a single ended RCA one?
I am currently using a completely balanced system. TT to preamp to amps. The cable from TT to preamp is inexpensive Mogami and the cable from preamp to amps is an even less expensive generic from Amazon.
I got the Mogami cable from the manufacturer who says that this balanced connection does not require an expensive cable and says the same for the other connection. IME with single ended cables, they make a very significant difference. Are balanced a different story?
