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.

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.
