What speaker cable made a major difference in the sound quality of your speakers??

Pretty much any 12 gauge speaker wire bought at Home Depot, Lowes or Radio Shack.  If you have the money to buy ludicrously expensive cables, put that money where it counts most and buy better speakers for your ears and tastes or be a slave to cognitive dissonance.

Thank you for saving us from this Tom foolery Edward. We've obviously been fooling ourselves for years and just needed you to set us straight. Praise jah!

Totally agree Todd.  It's just how human beings work.  Not limited to audio cables. It's true of all of us but especially when we consider ourselves "philes" of any kind. But hey, if you enjoy getting into the mystical nuances of subjectively undectable sonic details and it's worth it to you to do so, then have a blast, I don't really care.  But maybe someone reading this forum does.  After all, this is a place to buy things we otherwise couldn't afford new and so I assume getting ripped off is more painful for those buying here than those with the money to buy new at appointment only audio shops. Your mileage may vary.  Try doing some well controlled double blinds though if your confident.  Just a thought.

My bad, double post.
