@debjit_g After four years of work getting my Coincidents to finally sound like a reference, I'm not feeling a big rush to try new speakers, but I still like the idea of putting the neo driver in a 1cuft sealed cube for a diy project and change of pace. I'm very attracted to the idea of eliminating the crossover. If I do take the plunge, I will most certainly use the tempo Electric wire inside the cabinet. Would probably go with 14ga as that's what I currently use on my mid-range driver (20ga to my tweeter & 12ga in the bass cabs).
And @charles1dad I wonder if Israel's stated preference stems from the fact that he sells his own copper wiring. Replacing the stranded copper (with a Teflon jacket) in my PREs with solid core silver reduced distortion, and increased texture, color, and naturalness. As you stated, the silver sounds smooth with a subtle warmth. I don't hear any tradeoffs at all. The only downside is increased cost. I'm confident anyone with these speakers who did an a/b would prefer it.
And I don't blame you for leaving well enough alone inside the Coincident electronics. I've been using VH Audio's silver (5N, solid core) inside my electronics, but also still have a lot of copper in the various circuit boards. Routing new signal wire throughout all the pTp wiring would certainly be a laborious project. And as you state, they already sound so good...
Also, for anyone considering the option, Tempo Electric's 14ga is only ~$60/meter (x4 if you're buying a stereo set) with a 30-day free trial. It's a bargain.
