The frequency response curve of every speaker system can be very different. Some might have an elevated treble and some might be slightly dimmed in high notes. I understand that the tweaking of cartridge's loading has the effect of raising or lowering the treble. Isn't that the tweaking has a dependency on the speaker's frequency response curve? So the tweaking can be different from one system to another.
In other words, a 200 pf input capacitance may be right for you but for my system I might need 100 instead. Am I mistaken something here?
No, ideally there should not be no such tweaking specific for the loading - if so that tweaking option should be there for all sources. The cartridge maker tries to make the response as linear as possible given a nominal load. As everyone knows, the results differ between cartridges, from small to rather large. So there is an opportunity to make a custom load to fit each cartridge.
If there is a tweaking that has to be made due to nonlinear frequency response of the speaker, one can change the speaker to a better one, work with the acoustics or use tone controls. Then it would work better with the various sources (CD, radio, tape, streaming music, LP....)
