<html> Hi all, I was speaking with a Mapes wire representative at the NAMM show today, and he told me about a relatively new product they have. It is called International Platinum wire, and I gathered that it is similar to International Gold except for an additional surface treatment to make it resistant to corrosion. It is not plated or coated, but treated chemically somehow.

We've been using Mapes IG wire since it came out and have been very happy with it. As Ron mentioned, it's a lot cleaner. We've used it to replace Roslau in a couple of pianos that had breaking string problems and have found it to be some tougher. In terms of tone quality I'd rate them equal. I question the idea that either has "more shine" or more "brilliance" than the other. I'd want direct side-by-side comparisons using identical instruments. And that's not likely to happen.
