Not everybody is as in love with silver as you may be. It has its strengths and weaknesses, as does copper. I would guess it all depends on what aspects of the speaker you are trying to improve.

I would also think you should change out, upgrade or bypass the caps first, as that will make the biggest difference overall. Then you can adjust the other things if you still feel you need to. My first recommendation is to just bypass the existing tweeter caps with .1uF teflons of your choice, give them 200 hours of break in and then see if you need to do anything else. Then look to upgrade the other basic caps in the rest of the crossover if you feel inclined.

Yes, they make that much of a difference.

Enjoy,

Good info above. Keep in mind that some of these changes will produce strange effects at first(especially the caps). Many people will dispute the truth of "burn-in" for components and wire. To those that can hear it: No explanation is necessary. For those that can't: No explanation is possible. If you bypass: Don't exceed 1% of the value of the cap you're bypassing.
