“How often should I service my Naim product? This is a question often asked, and the Service Department recommendations are as follows: for the Chrome Bumper (circa 1975 - 1989) and Olive (circa 1989 - 2000) range products, we recommend every 8 - 10 years and for the newer Black products (2000 - present), every 12 - 15 years.”
That is completely my cycle - all my naim equipment is serviced from 2017 to 2022. After 10 years I will go for the next capping session.
My question is only based ion storing capped stuff and the chance of adding a bit not Top.
