to bi-wire or not?

For maximum benefits, separate cables should be used for bi-wiring, one for bass and one for midrange/tweeter. Also, the two cables should be separated 3-4 inches to minimize cable interaction. For my Vandersteen 2CEs. I used Kimber 8TC for bass and 4TC for midrange/tweeter. Heavier gauge is needed for bass because of the higher current demand of the woofer.

Thanks to both of you for the valuable input. When researching, I found the Rocket 44 to use PSC and PSC+ in their design and Audioquest has a paper on bi wiring stating the best way is to use separate cables. The next best is to use cables that can be modified for bi wiring, like their Rocket series, and to avoid designs that use a single casing (even their own, more expensive lines).

As I've already stated, I'm using 10GA on the base and 16GA on the mid/tweeter and I'm getting the most divorced sound from my speakers that I've experienced. Last night, I wanted to hear how the theme song to Breaking Bad would fare and ended up listening to the entire soundtrack. It was a kaleidoscope of coherence, if that's a thing. All over the place with effects yet focused, full and engaging, and seamless throughout.

I've already spoken to Musicdirect since they've been my go-to for my gear and those offers on the Rocket series cables are very tempting.

Bi-wire or not to bi-wire is something to test.

When doing so the I suggest replacing the original metal bar connecting the binding posts on the speaker with a better jumper to get a true A vs B comparison.

The metal bar connecting the jumpers are not exactly the epitome of design on any speaker nor something where materials have been meticulously evaluated and selected.

every time i have tried biwiring i find there is no improvement

The first thing I did when I got my speakers was to remove the brass jumper plates to try out some good cable jumpers and noticed the improvement. 

As for not hearing an improvement, I've read that not all bi wirable speakers have the crossovers properly designed to do that which can result in not hearing a difference.

What I'd like to hear is a side by side demo of the JBL L100 and the limited L100 Classic 75 which is bi wirable. Only 750 pair will be made.

All the best,
