Best component cables silver or copper

DH Labs component video cables work very well for me, and the LAT International are excellent for video as well. Both are copper with silver coating, though LAT explains that their coating is applied under high pressure (or something) to "fuse" the silver into the copper creating a near alloy. Silver plated cables have never worked for me for audio, but these two are the best video cables I have used. Curiously, the LAT International digital IC seems to work well too.

"to "fuse" the silver into the copper creating a near alloy."

This is exactly my problem with the dodgy marketing of some expensive cables. They use pseudo-science phrases like "near alloy" to hopefully impress hifi enthusiasts into thinking their cables are something special.
I'm sorry, but a metal is either an alloy (a substance composed of 2 or more metals) or it isn't.

We need to stop thinking some cable companies have re-invented the wheel; by all means test and compare cables, but stick to tried and tested cable designs from trusted manufacturers and you're unlikely to go wrong.

PS. Davemitchell's answer is very accurate - take his advice!

Carl109, did you confuse the information I wrote about as I remember from the LAT website as a personal endorsement of any of the claims? Personally, my first reaction was about the same: it cannot be an alloy unless it is an actual mixture. These things or sciences are not something I am an expert on, however. Still, we are on the same website and may even have the same opinion regarding manufacturers claims: but you did not know and seem to denigrate my post as a whole. Fact is, those cables work well for me and that's about it. I did not intend to offend anyone's sensibilities.

Glenn, my post was not at all intended to denigrate you or your post, and I'm sorry if you took it that way. I was simply responding to your quote of the manufacturer's claim about a special bonding process to produce a 'near alloy', which I assumed you'd posted accurately.

My point is that such a claim, if the cable company made it as you stated, is a misleading use of the English language to sound impressive. It's like saying someone is 'nearly pregnant'; you are or you're not.

That's not to say LAT haven't come up with some excellent cables. It's just some of the marketing that goes on to try to impress us (especially those who aren't experts in the science & physics behind their techniques) is something I find insulting. It happens in all markets, not just hifi, where marketing stretches reality as far as possible to make consumers think their product is the best and we can't live without it.
Just think how many people out there have bought high definition panels and are only using them to watch normal analog TV and DVD's, and will do so for years. They were convinced they needed a new plasma or LCD, when their CRT was probably doing a perfect job for their needs.

Remember, if someone stands to make money out of you, then don't automatically trust everything they say.
