Paradigm Reference Active 40 and CC capacitor replacement

[dlow]

I have a pair of Paradigm Reference Active 40 and a Reference Active CC. They seem to be working fine with no issues but the capacitors in the amps and passive crossovers must be getting very old. I haven't opened it up to see if any are bulging or leaking. Has anybody replaced their caps on these speakers? Or know of any sites where the project was outlined? I haven't desoldered parts for over a decade but might give it a try. Or should I not bother unless I detect an issue? Would an issue to very apparent (like not working or buzzing) or would gradual sound quality degradation be more likely? Thanks!
