Ditto on the Layne Audio, I live in Nashvile, Steve has has been to my house doing me a favor that was totally uncalled for and though we don't meet or talk often,I consider Steve a pure class act. Or you can sell these to me cheap, and I will have him fix them.
Now as far as upgrading the wiring, my opinion, don't. Replacing the caps and such is fine(as long as they are the same value), but if you play with the wiring, you are playing with the load and the design of the speaker. The speaker was designed using the wire the caps and the crossover and all the other things that are currently in it. Where yes, it could and can be improved on, I doubt you(no offense) or I have the knowledge or the proper instruments to measure and do this in our homes. Plus if you do try to sell them at a later date, I think the average buyer would rather have the original product that has not been tampered with, I know I would. Your call of course, but you did ask for opinions. I also have an acquaintance/customer of mine with a mint pair of these(original) that if anyone is interested in, I will forward his e dress.
