I'm not worried as such, but I do think it sounded better with the 1000pF cap; so I suppose I would like to get as close as possible without allowing the ingress of RF (which, unfortunately, 1000pF definately does).

Well Ive ordered some 2000pF polystyrene caps; so will see if I get any RF with them - if I do, it's back to the 4n7's.

so for my understanding the rf mod consists of
- the two moved resistors and - the tone arm earth connected to the incoming 0v star via 10nF capacitor. the 0v star is connected to the black snaic wire and the prefix case earth point. but where is the separate black ground wire from the nac connected to? 0v star?

thank you for this additional information, Darran.
so you think it makes no sense just to change the resistors positions and the tone arm earthing via cap? would be great if you can check the values and give me an hint which caps are changed. what about the separate black ground wire from the nac? is it really connceted to 0v star and then to the earth screw of the preamp? sounds like creating an ground loop and hum...

I just phoned Naim and they were kind enough to explain the required mods.
