Do capacitors really need to break in? | Page 2 | Audiokarma
If capacitors indeed "burn in" and it''s not our brains just getting used to the sound, then why do capacitors always seem to "burn in" to a more agreeable sound? If the characteristics of a capacitor change as it burns in then it would be just as likely for equipment to sound good when first used and then to "burn in" to something that sounds worse.
