the answer is a positive YES

recently i posted how interconnects made a difference. Tara Labs 5500i sounded more mellow and more agreable than monster THX (with music).

But now ive compared tara labs speaker cables (14awg) with Carol Superflex 12awg bought at home depot. I swear by this, cables make 110% difference for sure. There is no question, i gave them a very fair trial (to the point that i wanted HD to be the same! talk about bias i wanted them so much to be so the same that i went out of my way to do the trade!!) and the are not. As far as i am concerned, i am 110% sure that speaker cables DO make a difference. So, I will now look into higher quality (which of course comes with a bigger pirece tag) speaker cables. After all, i did spend a few grand on my system. Sorry to everyone that really thinks speaker cables make no audible difference - because they do! I swear by this too. So does my girlfriend to the point that not only did both of us say that Tara was better, but we both gave the same sound qualities that were different.

Again, sorry to all you non-believers because i really wanted to believe that there was no audible difference between speaker cables. Unfortunately (financially), there is.
