NuForce SC-700 all copper speaker cable were an inexpensive well made sleeper that were a noticeable improvement over the Cardas Golden Reference with all the switching amplifiers I've used.
I'm sure they're out of production by now. A thick rectangular copper ribbon wrapped in copper strands. I never found a switching amp that liked silver anything.
