It's digital, so there is no difference in quality, in principle, between different cables. No noise, just 0 and 1 that are being sent and received. And when they work, they keep working. No mechanical wear, no electronics inside.
So it doesn't really matter.
What 6' HDMI cable is best to hook-up my Blu-Ray player (Sony BDP-S350) to my Bravia 32XBR6? I need something that is pretty much guaranteed to last for a couple of years, because im going to get it phished through the wall.
