Pkoegz, When you mess around with very low output cartridges, there are many sources of noise besides RFI. If you hear noise, a careful investigation is in order to try to reduce it or eliminate it, but in some cases, especially with an all-tube phono stage, you may just have to live with a faint background hiss. I find this not to be annoying, since it is really only apparent when the stylus is up off the LP or during silent passages between cuts on an LP. In the situation you describe, I would advise leave well enough alone. There is no reason at all to fuss with the cartridge loading, and moreover, the loading will have only an incidental effect if any on "noise".
