Got a few questions about the Naim Stageline phono Stage. Any help would be much appreciated.
I wanted to change the loading on my Stageline K (560 ohms) I know the minimum loading for MC that Naim do is the S type at 470 ohms, but wondered if anyone has changed to a lower value such as 100 ohms? That would probably suit my Ortofon MC cartridges better. I also have a Linn Kandid that I think needs lower loading than that. The Urika setting for the Kandid is 42 ohms. The recommended range for the Kandid is 50-200 ohms. It does sound too bright at 560 ohms IMO.
I’ve looked inside the Stageline and located the loading resistors. What brand of metal film resistors do Naim use? I assume standard cheap metal films aren’t optimal?
I read that you can upgrade to Charecroft Z foil resistors but I want to try some different values in cheaper resistors first.
For the loading resistor positions, I might try to install some small screw wire connectors (or similar) so I can change the loading more easily without soldering (at least to test out the different values)
In this thread on the Naim forum, in post 5 a guy reckons that the differences between K and S aren’t just down to the loading resistors.

He says the S rolls off after 22 KHz but the K doesn’t
Does any know if that is correct or not? Are there any other circuit differences between the K and S apart from the 2 loading resistors?
