Seeing as this little guide was originally intended for people looking for older second hand bargains, I have decide not to try and keep current items on here (except a few things that have been around for a while). Naim's pages tells you all about those.
I haven't said anything about the really old preamps (eg 12S) which came in the old boxes. I feel there is little point as you can get more modern versions cheaply. I am not a world expert on Naim gear, and so if you think I got something wrong please email me and I'll correct it.
