Sounds like a better phono stage to me.
MC cartridges in particular are "loaded" by the resistance presented by the phono stage, to the point that it can affect the suspension and compliance characteristics. From Sumiko web site:

"The second aspect of cartridge loading involves how it affects the cartridge itself. When a load resistor is inserted across the + and – pins of the cartridge (typically using a set of switches on the phono section) the voltage that is generated by the cartridge flows through the resistor as current. The effect on the cartridge is an electromechanical stiffening of the suspension system and decreased output from the generator. The closer the load resistor value to the internal impedance of the cartridge, the greater the effect on the compliance and the lower the output voltage becomes. Hindering the compliance of the cartridge with too low a resistor value will stifle dynamics and high frequency response, and lowering the output voltage will force you to recruit more gain from the phono section or volume knob."

Good point. I didn't think of the effect on compliance due to increased or decreased magnetic field. But I also think that in the context of hierarchy, it just confuses things to start considering these extremely small forces. Let's keep it simple and in the context of Linn's notion of hierarchy. Now I'm thinking if a speaker would impact the performance of an amp. If so, there's no way to isolate the effect, and it becomes academic.

Both? But if we keep up this conversation, the electrical engineers will be laughing at us. :)
They already are.
Speakers do definitely interact with the amp. That still doesn't change the hierarchy in terms of what is important. What it does mean, and this is also true of the phono stage/cartridge interaction, is that the best of each product category can't be guaranteed to actually work together. So synergy does have to be considered.

Hope I’m not taking your words completely out of context, but this is why I stick to all Linn. They take all the guesswork out of it for me. I couldn’t face going back to mix and match with all the auditioning it would entail. Just too old for that now.

Well that's a belief system, there is more guess work to do than what any person or manufacturer can muster.
I mean that it limits my choice and I’m not constantly looking for the next upgrade. I’m happy with that.

I suppose it would depend on any hierarchy within the cartridge design itself (similar to LP hierarchy within the turntable) and how important this factor is (i.e. impact of phono stage) compared to other design factors within the cartridge.

I did that at one time, now I have wandered off the beaten path.
