If your preamp has stability problems, start with 100 ohms.
If your preamp does not have stability problems, you will be fine with the stock 47K. Loading has everything to do with the preamp and not so much to do with the cartridge when it come to low output moving coil cartridges.
The loading is killing a high frequency resonance that is ultra-sonic or ever Radio Frequency (RF) in nature. If your preamp does not care about that energy being injected into its input, the loading will have no effect. If you preamp doesn't like that energy, you will hear the effects of the loading right away.
