In reply to your first statement, I mentioned to Chris at Jupiter caps, asking "it seems like at some point you just replace the whole xover". His reply was that it was not the best idea to do that, and I think his reasoning was that if your values (ie. 6.8) are slightly off for a number of different parts, it can throw the crossover askew from what it originally was intended. Also, if you just replace a certain value (6.8uf) and something weird happens (besides better sound  :D) you know where the problem is.
As far as describing the sound: I believe the 6.8uf cap has to do with the higher frequencies (there, you see how ignorant I am of electronics) but I'm not sure if this is just for the horn tweeter or if that includes the upper mids. At any rate, the reason I looked to replace it in the first place is I was wanting more detail and air. It always sounded a bit dulled, and the reason, I believe is the parts in the crossover.
Well, I was and am very very pleased with the result, and now hear much more air and detail and strings, horns, whatever, are perceived vertically as well as more image depth and detail.
   We spend a lot of money on cables and components and tweaks, trying (I believe) to get speakers to sound better when they are filtered via a crossover with lesser quality parts, and only replacing these parts give us a real window on what these speakers can do. As always YMMV, but I wholeheartedly recommend upgrading if you plan to keep your speakers. Of course you can always put the old part back and stuff it back in the cavity....

I only use copper foil caps nowadays.  Because I don't want the signal passing through tin foil or aluminum foil.  That's going to degrade the signal. 

From my DAC, to my preamp, to my amp, to my speakers - all capacitors in the signal path get replaced with copper foil caps.  I'm not sure it "improves" the sound, as much as it removes inferior parts from the signal path that were degrading the sound. 

I mean, you would never use an interconnect or speaker wire made out of aluminum foil, would you?  Then why would you be OK with capacitors made out of anything but copper?

That’s why anyone who sort of knows what they’re doing would at least measure and test everything before hand. But even if I sort of knew what I was doing (and I don’t) I’d rather go the distance and hire a real expert for obvious reasons. Nevertheless there’s quite a bit of information on this subject here on AC that’s worth looking into before plunging in.  :thumb:
