"So do you consider the cartridge loading as a fine tune of the 47k phono circuit?"Well, as I said before the circuit being changed is a combination of resistance, capacitance and inductance. These three elements in whatever combination occurs in your preamp (and practically no one knows that that actually is) create a filter. Changing the resistance changes the filter. It also changes the impedance which affects the frequency response of the cartridge.
So consider it what you will. Since the actual value of the resistance is somewhat arbitrary, there is no "correct" value for a given cartridge, the use of a 1% resistor only helps assure channel to channel sameness without actually measuring the two resistors first. I use standard 5% film resistors and actually they are more like 1-2% when a small grup are measured. But it doesn't matter unless you intend to create a given know impedance value and want to be dead on but that is different from empirical listening tests.
Cheers!
