Definitely worth it. You can not only get "close-to-new" or as close as you can remember with decade-old gear, you can also get better than new thanks to evolving designs, component improvements and so on...and when you get these in the course of "routine service"--figure it out.
Naim Recapping
I have noticed that an apparent disproportionate number of sellers of Naim equipment make reference to the need for recapping; or the date/interval since the last recapping. One rarely sees that for other electronic components. What is different about Naim components with respect to possibly more frequent recapping?
