Early Naim

hi i have an early Naim NAP 120 amp and NAC 22 preamp , does anybody know much about these products, also i would like to upgrade the interconnects , remembering as with most Naim the pre amp is powered by a 4 pin din cable

any advice would be welcomed , thanks very much
You should go to the Naim Audio website and forum.
All the info you could ever want will be available there.
There is actually a page dedicated to the history of Naim gear on the site.
Contact Audio Concepts in Dallas TX. The owner is also the U.S. importer for Naim.

Happy Listening!
