Hi Guystp,
Glad to hear that someone else prefers the Horizon SE! The dealer I use now that sells Naim gear (but not Nottingham) does sell Dynavector cartridges, so I will definitely check that out when in need of an upgrade. I have the Clear Audio turbo counterweight on the RB 250 tone arm and it has improved wiring in it according to the dealer that sold it to me.
