OK, OK, before you flame me, I already know it's a bad idea to connect an amp output to a speaker using instrument cable. I never do it... I once did a test comparing the two - it definitely sounded different. what I'm wondering is electrically, why is speaker cable "better" to handle my amp's output to the speaker cabinet? Hope you guys can tell what I'm asking...are the picofarads divided by the ohms to the millihenrie's power going to blow up if I use instrument cable?
