Have you upgraded the thin speaker wires provided with the HT? I've had my Onkyo HTS-660 for a week now, and am loving it. The wires provided are just the right length to provide me with great 5.1 surround sound. There is absolutely NO hissing or popping in any of the speakers, and I'm using the thin speaker wires provided with the package. For those who have upgraded to thicker gauge wires, did you notice any difference? Is it worth the "upgrade?"

Thanks!

I never even hooked my system up with the supplied wire, i went straight to a 16 gauge from Walmart.

If I remember my HT theory correctly, the thicker wire will have an immediate effect in lowering the operating temperature of the receiver. A good investment for the longevity of the unit.
