7N OFHC Silver Plated, just arrived yesterday. Before that I was using some mystery Rhapdosodio cable that was blue in colour.
I cannot work out what metals are used in this blue cable below, but it damn sounds like silver to me? Maybe Lin knows, he was on the tour.
Has large airy soundstage and made the mids sound thin but well detailed and was rather bass light. When I first plugged the new SPC cable in it took a while adjusting, I had to second guess I was actually upgrading for an hour over the blue cable but the SPC certainly makes the mids thicker and expresses better bass impact.
If you ever get a chance to try one of these mystery cables I recommend doing so....
Yes they're, I can get them for about $1.00 a pair.
If I remember correctly, the blue cable was copper, but man, it just could not stay still. Might have been a mix of copper and silver, but I'm pretty sure it wasn't pure silver.
I bought a whole bag of Heir tips as well, they're great and have a large soundstage.
