Balanced vs unbalanced: a suggestion that someone needs to bone up on their tech:
Invalid Link Removed
Balanced vs unbalanced ALWAYS refers to a line-level signal, not a speaker-level signal. these are two entirely different things; voltages, impedences, etc are different, etc. Think of line-level as before the amp; speaker-level as after the amp. line-level wiring is very thin, usually +- 22 AWG. Speaker level is (should be) twisted copper of 16 AWG or greater. 14 and 12 AWG are not uncommon and allow for greater power . No such thing as balanced speaker cabling. You always want to use a speaker cable to connect a speaker cabinet. If you use a guitar cable (which is an unbalanced line-level cable) you can fry the amp from heat build-up.
