Umm, that is not the gauage of the wire. It is the model number of the product that Monster Cable is selling. HDMI probably uses 24 guage. Speaker is 10 or 12 gauge for the good stuff.

-- Now before we jump into this conversation, it's important to note that any hi-grade cable is going to be an improvement over crappy low grade cable. But when you start making values on the difference between 600 gauge cable and 1000 gauge cable, is there really any difference?
If you are talking about the model number than difference is small to the average eye. Just buy the cable for BlueJeansCable.

Lets say for example, you are running HD Direct TV. That signal is coming into your receiver on a COAX line anyway. And since digital is simply transferring 10011000101. Why should the cable make a difference except to block out interfearance?
Depends! Short or long runs?

-- Some people have said that companies like MOSTER have made hundreds of millions of dollars selling people stuff they don't need. For example, huge gauge wire and power conditioners. (My electrician has told me over and over that California's power is very consistent (at around 118) or something and there is NO need for expensive power conditioners... It does not improve quality of signal.
I have seen the home of the owner of Monster Cable on TV. He is making a killing on his product.

So I guess one of the questions here is, diminished returns. When do we reach diminished returns on cables and what is just a waste of money. Of course for speakers it's important to run thick wires, and you should always use HDMI vs. S-video, etc. but at what point are we just spending more money on stuff we don't need?
We are suckers for pretty cables. My plasma is mounted on the wall and all my wires are routed in the walls.

I recently bought a 1080p plasma and hooked it up to my PS3 for blue-ray. I connected it using a 600 gauge wire from monster (vs. a 1000 gauge wire for monster) and I could not imagine this tv being capable of having a better picture regardless of wire. The picture is insane.. So who is buying these 1000 gauge wires?
The Audiophile buys them and the average consumer does. Please remember 1000 gauge is not correct.
