there are even some Sony surround receivers that people throw out, that are all done (completely!) in ’nichicon muse’ capacitors. This is no small thing, regarding final sound quality. Re-capping old gear exists as a known phenomena - for a reason. It’s not just the age of the capacitors, it’s the quality of them, how it affects the signal reproduction.
eg, the Sony STR-DB930. (possibly the DB940 as well. And others) Done in extreme grade capacitors. Lots of them. Not cheap to execute. I would not call Sony a dumb company, either. (with regard to sales potentials which, in turn is - costs incurred vs retail price)

Here is a video of a (lets be kind and say he’s kinda iffy in his tech skills) gentleman opening up a DB940. Note that even the speaker wiring is swapped out to a non normal set, the kind of swap we accuse ’audio modketeer hacks’ of doing in gear. The kind of extremism that can make it look overly busy and ’hacky’/clunky in a ’19 year old adding a turbo to his honda’ kinda way. You can see it in the DB930 image at the upper left, peeking out just a bit, between the circuit board and the metal support structure.
Yet Sony did it right at the factory. The wiring I’m speaking of is the copper wire with the transparent skin. That’s the speaker wiring from the main amplifier board that goes over to the speaker terminals. If Sony does such things right at the factory, then the modketeering types aren’t all that crazy, are they?
Audio extremism. It’s a thing. Even at the multi-billion dollar corporation level.
