[QUOTE=richteer;1035418]Umm, why would copper or silver cables have iron in them? Dunno where you read that OFC has a deletarious effect on sound...
There is a link below where I found part of the info about OFC cable it is about copper wire. Scroll down to: "What about oxygen free wire?". The resistance is increased after the process. There is I think two other websites where I read info about "speaker cables" and do comparisons. Some of the info was also about untreated connectors. I didn't bookmark them and will have to back through and find those articles.

I am just trying to make sense of "speaker cables" in general and sift through all the info. Cables costing $250 each and cables costing more are where it gets frustrating. What makes that cable so great and is it just a claim? Before I make a purchase I want to make sure why that cable is great or better. After all I want to do what is best for my system now and in the future. I will find the other articles soon and hopefully they will be of use to others.
For people who already own expensive cables- what lead you to buy that particular cable? If I'm going to spend a couple thousand dollars on cables I have to know "why" those cables are the ones to get.
Also sorry if I'm trying to get too technical but after all wouldn't we want to sort through the hype and get down to what is a great speaker cable and why? It's not like you can borrow speaker cables to test out.
