Umm, try reading the second reply to your post. I did try replacing the straps with speaker wire. I was even expecting there to be a change (which tends to invoke the placebo effect). The fact is, I heard no change at all.

And don't knock math. The fact is, cable length is one of the most important variables when you're discussing signal integrity. Even the best cable in the world will fail to transmit a signal with integrity if it's too long.
