Bought these new in 98/99? Used them until 2010 when I bought some high priced shorter runs. Sonically these perform as new. Cosmetically they have flaws. The brass collars have the ugly black oxidation. When they are unscrewed the inside is not affected. This has no effect on sound and when hooked up is not that noticeable. The banana connectors look fine. Jackets look very good. For the money these punch above their weight. If curious about the benefits of biwiring, here's your chance to try at a low price.
