I'm a big fan of Belden cables, but why go to the trouble of a group
purchase when it is so easy to make your own twisted pair from lengths
of stranded cable we can buy at the local big box store? The Belden
cables referenced are primarily used for loudspeaker wiring in big sound
systems. I specified a lot of it when I was designing systems like that.
Another point though. Hams in general, and Elecraft in particular,
should be using twisted pair for loudspeaker and power wiring in our
stations. It's not a cure for RFI, but it is a positive step, because it
prevents differential mode coupling of RF to that wiring. Ditto for
loudspeaker wiring in home entertainment systems. Over the years, I've
cured lots of RFI to these systems by replacing zip cord, glorified or
plain, with twisted pair.

Belden appears to make a 10 AWG twisted pair cable, but I only see it available in
500 foot spools. Search for "Belden 8678”.
Might be worth organizing a group or club purchase. Or maybe PowerWerx could
carry it.
