What's the best HDMI cable that you have tried ?

Parts Express Flat HDMI cable. I tried 5 aftermarket more expensive cables until I stumbled upon one of these. Ultimately replaced all five cables in two systems.

Ya, me 3. (After incorrectly assuming more expensive is better.) I own one of them there 6 hundred dollar WireWorld Silver hdmi's.
I have 2 cable boxes going to the same tv and the freebie from TWC is the WW's equal.--Why would someone need 2 boxes going to the same tv?--I can record 2 programs at the same time and watch a third,on the other box. Also, I can give the programs I'm recording a head start,(NBA finals)then zoom thru the commercials.--My tv is the Pioneer elite plasma,60 inch-er.

The Amazon's Ultra-High-Speed HDMI Cable is fantastic and a great value. It is very well shielded. I can easily see the difference when
comparing to a stocked cable. Playing the blu ray disc "Up", I can see noise in the blue sky with stocked cable but it is
absolutely noise free using the Amazon cable. I got it for $19.95 (3M) but its price has gone up to 25.90 recently but it is still a great buy
IMHO.

All I can say is that my wife knows nothing and cares less about audio and video and she had no trouble seeing the difference between first the stock cable and the Monoprice and then between it and the two more expensive ones. Of course we have Direct TV; I have never had a cable picture I was happy with.

Dave Schulte of the Upgrade Company did some tests with 1 and 2 meter HDMI cables last summer. From these tests they found out that 2 meter cables performed far better vs 1 meter cables. The best performing HDMI cable from these tests was the WireWorld silver starlight 5.2
