I bought my Rotel RA-931 back in 1997 and its been turned on every day since then, and still sounding sweet.

Ive had a Rotel RA931 amp for going on 25 years now and I suspect its not been turned off since I first plugged it in and its never skipped a beat. Coupled with some Ageas AE1 speakers that I listed to in the shop and I’ve never felt the need to mess with.
