I replaced every passive part from the binding posts to the driver hookup wire.
Binding posts: Cardas "CPBP" (rhodium over silver), dual for biwire
Woofer in: Cardas 2x15 ga twisted pair plus 2x17.5 ga hand twisted (~14 ga equivalent)
Woofer out: Cardas 2x15 ga twisted pair
Coax in: Cardas 2x15 ga twisted pair
Coax out: Cardas 2x17.5 ga hand twisted
(wire gauge per Tom Thiel recommendation; OEM wire was 18 ga throughout)
