I don’t change HW much. I replaced my DIY speakers two years ago after 25 years and the CD player (XA20ES) after 21 years. I guess I’m blessed with poor ears and could never discern differences between much of the electronics and ancillaries.
I keep tweaking my listening room acoustics although “the” final adjustment/ change should be finished in the next couple months. Really. I’m serious about that. Done ;-)
I focus on the music. Just got a book “1001 albums you must hear before you die” by Robert Dimery. Rough count, I only have ~ 2% of his list. This should keep my busy for a while.
