The point in trying different HDMI, if I had not heard the AV8003 before I bought it the first cable would have me experiencing less than optimum performance because I would not have known any different. I knew the AV8003 in my home was less stellar than what I had heard in the store. The HDMI was not the first attempt to fix the issue, in fact, it was the last of several. No matter what the difference in HDMI cables is from, build quality or whatever, that still is a difference.
