Again there is confusion between a "balanced" interface, and "complementary" circuitry. Complementary circuitry may have unbalanced input, and vice versa.
Balanced interconnects avoid noise pickup in the wires, and only in the wires. But, for any decent single-ended interconnect, of reasonable length, and outside of a bad environment (like being bundled with other wires) there is no significant noise pickup in the wire.
FWIW I do use balanced wires out to my power amps, which are 25 feet away from the source, but this is just because the electronics happen to have balanced interfaces. Results are no different from when I used single-ended interconnects with these same electronics.
