While I may be repeating some information contained here, I doubt anybody has made this kind of comparison. I argue that you don't need to spend a lot of money on any type of audio/vidoe cables. Also, that HDMI isn't worth it. There might exceptions for audio, but that's beyond the scope of this article. I used the following equipment:
Sharp 37" 1080p LCD, calibrated with Avia II
Toshiba HD-A3
$10 Component Cables
$80 Monster HDMI
I connected the HD DVD player with both cables to two different inputs on the TV and then cycled between them. What I found is that there was no practical difference between these cheap Component cables and HDMI. This counters the argument that you may not need expensive cables for HDMI, but you do so for Component. I wouldn't waste more than $20 on any audio/video cables.
