What is your favorite line-level wire, single-ended & balanced? Mismatching is OK. Source & estimated cost would be helpful.
Only 10" pigtails, no or minimum shielding is OK
Hard-wired switchbox requirement: Moderately easy to bend (my favorite, twisted-pair AWG12 is way too stiff); conversely, must be moderately durable (no super-delicate easily broken).
TIA!
