The Kappas I had were wired with clear insulation. I would think one has been modified. I would hesitate to call it an upgrade.
Infinity Kappa 8 wiring?
A friend has the 8's and noticed black Monster wiring on one speaker and clear smaller gauge Monster on the other speaker. His serial numbers are close but not sequencial, KO43968 and K043976. He just wants to know if anyone knows about this. Thanks, JAY
