Fleib, I recommend you do some design work and see if you still say that. You might also do a search on some of the comments by the Jonathan Carr (Jcarr) who is active on this forum.
The cartridge/cable combo acts as both. It does not matter that the phono section has no bandwidth at the resonant frequency, which is usually several MHz. The gain has nothing to do with it.
I wonder if there is a semantic issue underpinning this conversation. In the above quote you are correct in almost every way except that there are no LOMC cartridges with high inductance... if it is assumed that by 'tiny voltage' you are referring to about 1.0mV or less. The inductance you thus refer to is the inductance in question, the frequencies are those in question, and no phono section I know of can go that high, but they don't have to- they only need to have an RF sensitivity and then you suddenly hear loading making a big difference.
But here in your next paragraph you seem to contradict the earlier paragraph in the first sentence. I did not nor do I assume that the 'higher the load the better': I said the correct load and most designers design for 47K.
I agree that loading affects these things if your preamp has RFI problems! I don't know if you have ever heard what RFI can do to an audio circuit outside of a phono situation but the effect it can have on soundstage, background noise, detail and the like can be profound. As a result all I can assume from your reactions here is that the phono sections where you have tried different loading options are all having trouble with RFI; that is why you heard a difference! RFI has big effects on audio gear if not tamed.
I do however agree with your closing statement as loading has a lot to do with both the cartridge and the individual preamp, for the reason that the inductance of the cartridge and the resulting RFI affects different preamps differently. In our case since we got a handle in this some years back it has almost no effect which is good- its more plug and play. But we originally included the loading strip on our preamp (which is still there) because in the old days we heard differences with nearly every preamp we auditioned.

If a circuit does not have RFI problems then loading can still have a beneficial affect.Loading of LOMC cartridges has no effect whatsoever so far as the cartridge is concerned. There is a slight benefit to loading as low impedance terminations of cables reduces cable artifact, particularly with high capacitance cables. This is better realized if the cartridge is operating in the balanced mode (as it is a naturally balanced source) and the signal is carried through a balanced line. Then the cable will have no artifact at all. 600 ohms will be sufficient to eliminate the cable artifact.
Novel way of looking at a generator, or is it a transmitter? The oscillation or ringing occurs in the preamp because of the extraordinary amount of gain needed.
The cartridge/cable combo acts as both. It does not matter that the phono section has no bandwidth at the resonant frequency, which is usually several MHz. The gain has nothing to do with it.
The tiny voltage of a LOMC still has inductance, which combines with cable and preamp capacitance and can cause HF ringing, but is only a problem with extremely low output carts with high resistance/inductance. I think such occurrences are beyond the bandwidth of your phono stages.

Saying RFI is generated by the cart is misleading. It is not. There are other loading considerations with MC's, none of which are about noise or tonality. You assume the higher the load, the better. I beg to differ. Such things as imaging, stage, dynamics, detail, and focus can all be affected by load, while tonality is unchanged.
