I have been considering the replacement of the capacitors in my speakers which are approaching 20 yrs old. I’ve always heard that 20 yrs is the life expectancy of caps, thus my concerns. Beside that is that I believe there is a slight loss of transparency over the years or expectation bias at work?, Even so, I like the overall sound signature I have and want to keep what I have, if for no other reason, the $12-15k replacement cost. I was told that if I replace with the same values, it should be fine
So, the question is it a good thing to do as a maintenance project? Then too, which capacitors? Nichicon made a big improvement to my 20+ yr old preamp. Are they appropriate for a speaker (original Silverline Sonata)?
