OMG, I can’t believe what I’m reading here. Speaker cable burn in? Are you kidding me? In this universe, what magical, non-scientific process are these speaker cables going through that’s going to change their physical characteristics? Basic physics people - there is nothing you can do to speaker wire by hooking it up from your amp to a speaker that will ever cause it to change itself. You can get your cables cryogenically frozen, add batteries to them, twist in a few "feedback loops" and it won’t change the wire or the manner in which it carries a signal in any way.
Yes, speakers go through break-in periods and electronic components do go through what one might term a "burn-in" but wire is wire. Some good 10ga stranded copper wire is all you need to effectively get the signal from your amp to your speakers. If you actually saw the wiring used inside your speaker to go from the terminals to the crossover and the various drivers, you’d probably faint. You can spend all you want to get that signal to your speakers but on the other side of that terminal you just connected to is much lower quality wire heading to the crossover - industry standard stuff. Don’t get sold on all this hype and snake oil that’s out there.
