This Popular Mechanics (PM) article is one of the best myth busting articles I have come across in a while.

Just want to say the following is half true and half false:

Quote:
Myth #7 To get the best-quality HD, you need expensive cables.
Fact: Not true. If the cables running from your DVD player or cable box aren?t particularly long, you should be fine with inexpensive video cables. The extra shielding in expensive cables that prevents interference in analog equipment won?t improve the image of digital video through HDMI or DVI cables ? the signal either comes through or it doesn?t. And the savings can be huge: 6-ft. HDMI cables range from $20 to $160
OK, I am definitely in favor of people getting reasonable priced HDMI and certainly do recommend monoprice for HDMI to my friends for example.

But but when you read anywhere "digital signal either comes through or it doesn't" you know you are getting amateur advice.

Runs of HDMI degrade quantitatively for certain. they are not either perfect or total failure. You will absolutely get sparkle, tiling and other problems gradually increasing at any length over a couple of meters at the common 28awg (guage).

AS lot depends on port voltage. certain equipment like moto cable boxes deliver pretty strong voltage. others like oppo dvd players deliver notoriously low voltage at the digital port.

Well we are talking about HDMI cables here. Honestly you points are well put but there are two types of Digital connections (in general). They either incorporate error corrections or they don't. HDMI (and DVI-D) don't incorporate error correction which makes them a little more vulnerable to transfer errors. Even so HDMI still has a certain Bit Error Rate (BER) at certain speeds and frequencies.

Quote:
A recent development includes an effort to stuff sophisticated electronic circuits into the assembly of an HDMI cable. At least one company would have you believe that HDMI-qualified cables from established vendors generate hundreds of pixel errors, that it incorrectly calls 'pixelation', continually visible on-screen. Sorry, video images with hundreds of consistent pixel errors correspond to a BER of at best 100 in 2 million (1080p resolution), or 50 in 1 million, at least three orders of magnitude worse than the DVI specification of 1 error in 1 billion. Could a manufacturer have supplied an HDMI-certified cable with this performance or absence of quality check? And no, I do not think removing sophisticated electronic circuits that are easily integrated into chips at either system end of a typical HDMI link, and stuffing them into connectors in the cable is lower cost, higher reliability, easier to use, or of better quality!

On a short run (under 35 feet) there is just not enough mis match from point A to point B to require anything other than a standard quality cable build.
