I too am using Straightwire component cables. I use the silver ones...whatever they are called? They replaced a set of low end Tributaires which in turn replaced a cheap set of Monster's. Definite improvements on each consecutive upgrade. And yes I did demo each cable before buying with a friend doing the plugging and unplugging Each upgrade yielded slight but still definite improvements in picture quality.

Anyway glad to see that you had a positive experience on the upgrade path
