I thought this discussion had been resolved 5 years ago.
The answer is: High quality cables make a difference in noise rejection, and signal quality. Will anyone notice that high quality cables have slightly better noise rejection or slightly higher gain than a cheap cable?
You can best your ass they won't.
The only scenario where an expensive cable is a better choice than a cheap cable is for long lengths where potential noise is a concern, or where it's a long run inside a wall where replacement is difficult or expensive, or where the reliability is mission critical.
I've had a few cheay Hdmi cables die on me, but they cost less than $5 inc p&h, and they were subject to constant plugging and unplugging into myg laptop. Under those circumstances, it's not likely that the higher quality cables would hav made any real difference, except to my wallet.
It's not environmentally friendly, but until someone makes a heavily robust hdmi cable, the cheapies are the only feasible option.
