I've been using lamp wire for 40 years, I just get stranded 16 ga. probably overkill, but has more strength and rolls up better. I replaced the z5500's wire in the studio cause the orig. was to short. I look for the heavier insulation when buying wire, it lasts longer with fewer skins and kinks. I bought a 200' roll when replacing in the studio used about half of it, think I paid $22.00 for the whole roll, could have got the same ga. with less insulation for about $10.00. Unless you're wiring is laying on the stage with people walking all over it bigger is not better, same for speakers, bigger is not always better..........Pose
