Yes, I have also rewired the inside of my Klipsch (Chorus II). I had some scrap Audioquest Midnight speaker cable around that I used which really removed a lot of the glare. The cat-5 cables may just need to be broken in or maybe they are just to bright. I also replaced the caps in the crossover with some Jensen Oils and a large Solen.
I am not about to experiement with attaching some rope calk to the drivers to see if I can get them up to the next level. Do you have any experience doing this or maybe dampening the inside of the cabinet?
