Are 'Monster' Cables Worth It?
Digitarius asks: "Are "Monster" cables really better, or are they just more expensive? I'm setting up my HDTV, and I can get Component video cables made by Belkin for half the price of the Monster cable equivalents. Are there any actual stats or studies to back up Monster's claims of superiority? So far most people tell me to get the Monster cables, 'just to be sure,' but what's the real truth?"
Firingsquad did a test between different brands and different types (rca vs svideo). The results where pretty interesting:

Monster Cables are a giant scam designed to relieve gullible people of their money. Double-blind testing has shown time and time again that you can not physically perceive the difference.
There is a huge industry around selling useless crap to people. Monster cables will give you about the same results as rocks. (Yes, people buy those rocks and yes, they think they make their stereos sound better.)
I highly recommend that you check out the James Randi Educational Foundation, and do a site search for "audiophile" or the like.
Frankly, I don't know what scares me more: the fact that someone will honestly claim that a magic rock will make music sound better, or the fact that people will pay good money for one...

When I got into audio I thought all of these things mattered, but I slowly realized that I couldn't tell the difference. Much like I can't tell the difference between a diamond with E color and F color. 12 years ago back a company introduced a cable that somehow carried different frequencies at different rates or some other similar magic - I really can't remember. A friend of mine swore he could tell a difference, I couldn't. He dropped hundreds on the cables, I didn't.
Visit one of your friends who is recommending monster cable, listen to his system. Swap the cables with lower-end ones, and see if you can tell the difference. That hour of time may put your mind at ease.
I can't say that I did an empirical review to accurately measure differences, but recently I purchased an HDTV and was wondering the very same thing. I tried several different "just normal cables" one being the cable the cable company gave me, one being regular coax, one being a cheap svideo, and one being a top of the line from radio shack, and a component video set from Monster. The coax was the worst of them all, the sideo cable being second worst. Then came the cable company component, which still wasn't that great. Some of the colors seemed a little washed out, and I could see some signal noise, but that was probably due to my setup. Then I finally tried out the Monster cables. I saw an immediate difference over all the previously tried, the signal came in nice and clear, and there was no color bleeding, and no signal noise visible on my screen. But of course results may vary.
I would personally go to a store, and keep the receipt and just try it out, and see if you notice a difference.
I was recently shopping for a DVI cable for my HDTV, and was blown away by the US$80 AND UP prices I was finding around town. 80 bucks for a bloody 1 meter cable!?!? Thankfully, someone pointed me to http://www.pacificcable.com/ and I found a 1 meter DVI-I Dual Link for $22. (I am not affiliated, just a satisfied customer)
The Monster-type cables are the profit center for the A/V stores. They have to compete for pricing on the actual gear, where they may get less than 10% markup from their cost. On cables and accessories, they can get up to 40% or more. There is no way that one cable is better than the other, provided the connectors make good contact at the jack. Don't waste your money.
For the physics inclined, have a read here about skin effect in audio cables.
The basic idea is that electrons ride the outside of a conductor, not equally through its cross-section. The depth of the 'skin' depends on frequency. You might think that stranded cable would do better then, since there's more surface area, but because the strands aren't insulated they act as a single conductor, providing no skin-effect benefit. There is an exception, cables of 'Litz' construction, where each conductor is individually insulated, creating a virtual cable of effective diameter without skin effect.
My take-away from the linked article is that skin effect does have a slight effect on sound quality that can be measured and possibly perceived. Swinging back to the topic, Monster does make a Litz speaker cable, but it runs you $1500 per 3-foot cable - this isn't Best-Buy level Monster cable. A Google search on Litz at monstercable.com only provides two hits, both 3rd-party write-ups.
So to achieve top theoretical sound quality, assuming good connections, etc., you can buy thousands of dollars worth of top-quality Monster cables or cheap cables with fat conductors. If gauge and weight are far more important than cost, say on a Space Shuttle or similar, then dropping $10K on speaker cable might be worthwhile.
This all has me wondering of anybody here has used 10-gauge Romex as speaker cable.

I noticed that I had much better colour (indicating that before I was suffering from signal degradation), and the lines displayed by my TV were sharper.
My empirical observations have proven your physics theory to be false;
Do you have those plots handy? What device were you using to measure colour and sharpness? Without hard numbers, it's really difficult to show that you weren't actually just really excited about the really expensive cables you just bought and tricked yourself into thinking that they were better.
Don't get me wrong, I'm not saying that the cables might not have a better picture.
There is also capacitance and inductance to take into account. Video sits around 4MHz (off the top of my head). At frequencies like that you can definitely have cable effects too, which essentially results in a low-pass filter. This would attenuate the more subtle details (edge sharpness for example).
Recording and video studios don't tend to use Monster cable because they also don't tend to use RCA cables to patch things together. Too easy for noise to get into the signal path. They tend to use balanced lines so that any noise can be self-cancelling (if you're interested, google "balanced line driver"...that ought to give a few hints).
The wire you find inside your speakers is specifically designed to maintain it's form, take high heat, and/or lie flat (for the wire wrapped around the former), or to be flexible enough not to come apart (for the wires going from the terminals to the cone/voicecoil). They're typically made much differently from speaker cable.
If you want to talk to people that know more than a little about pricey cabling (rca cables, at least) talk to a reputable car stereo shop. Home theater environments have only a tiny fraction of the shielding, grounding, impedance-matching, and noise problems that automotive applications do.
Most of the expensive home theater cables are shortened or rebranded versions of ones that were developed for automotive use. Noise rejection characteristics, signal path length (both parts of the path being equal), shielding type, and overall cable quality (fit, insulation, solder joint quality, etc) are all part of what makes expensive cables cost as much as they do.
If you're hooking up a TV and a DVD player with connectors 3 feet apart, most of the design features of the expensive cables will be unnecessary simply because there won't be that much chance for noise to enter into the picture. If you have preamps, amps, multiple sources, multiple grounds, noise sources, long cables, etc. the expensive stuff just might make everything work better.

Don't rob him of his fantasies. If he defines the cables needed as a percentage of the system cost, then let him be. For systems over $200 you definitely need the Mosters. Actually, on occasion it has been observed that they are needed even for systems at $179.99, and there is anecdotal evidence of one case where they were needed at the $149.99 price point, though that is up for debate.
Bullshit gold is the best conductor. Silver has much much lower resistance.
If I had a bull that was shitting gold, I wouldn't waste it by using it as a conductor.
I'm just sayin'...
I noticed another electrical engineer responded to this as well, and already explained that the skin effect kicking in at 100KHz is dead wrong. I did my masters in RF engineering, and I had access to very expensive cable testing equipment (It was actually a system designed to test just about anything including amplifiers, but you could use it to test cable). Another grad student was wiring his house, and was pondering the same question, so we put the cables on the machine.
The Monstster cables did much better, but above 100MHz, way above anything you could ever hear. We tested 16 gauge lamp cord (YES LAMP CORD). It's spectrum was perfectly flat to within 0.1dB out to in excess of 10MHz. This FAR exceeds the 0.02MHz the human ear can hear. For audio purposes, it will work just FINE. As for shelding, the frequencies that you will pick up from that stretch of cable won't be audible. And if you're paranoid, stick an RF choke coil on your cord (you can get them at Radio Shack. You just wrap the cord through it). Those don't kick in until about 50+KHz anyway.
Video is a different ball of wax though since it deals with much higher frequencies. But after testing several cables, the mid-range stuff was not much different than the high end stuff in the area that counts (below 100MHz). The cheap stuff did start to have some attenuation issues above 10Mhz, but even then it wasn't that severe (1dB or less upto 50+Mhz). However in the higher frequencies, you have to worry about sheilding a little more as the frequencies that it will pick up via radiation could be visible. But any properly grounded coaxial cable will eliminate that.
As for ecording engineers, they are obsessive, but they aren't stupid enough to use straight cable. They use the same priciple as ethernet and twisted pair communications. They transmit the signal and the inverse of the signal and run them side by side. If one side picks up interference, the other side will too. But when you take the difference between the cables, it will remain exactly the same.
Karma: Abstruse (Mostly as a result of using words nobody understands)
I can't overemphasize the importance of making sure that the length of the cables carrying the (nearly) 300,000,000m/s electrical signal before it turns into 340m/s sound waves be within a few angstroms of each other.
Oh, don't forget to use a micrometer to set the distance from each speaker to your ear to make sure the sound waves arrive at the right time.
Dewey, what part of this looks like authorities should be involved?
