Replacing caps on crossovers?

Thanks for the info so far, my speakers are Naim NBLs and the crossover is separate from the speaker and mounts on the back. Looks like it would be very easy replace any given part. The speaker is designed to be used passive with the crossover and active. The gains going active are apparently huge that makes me question if crossover parts are improved will I get part way there?

I've asked Naim for a schematic, see if they provide one. What prompted me on this is I'm replacing some caps on my DAC soon with some Duelunds. I suspect my speakers could be improved as well only worry about messing with the balance of them because they could be voiced with the lower quality parts. I might end up with a different sounding speaker that I don't like.
