Question on loading and interconnects

I'm having trouble wrapping my head around how length and capacitance of phono cables affects cartridge loading.

I am currently loaded at 400ohm, which is the max setting below 47k on my phono-pre.

Is there a way I can experiment with cables (higher or lower capacitance maybe?) that will create a percieved load closer to 1k or 1.5k ohm?

Any info appreciated, as i'm pretty much clueless on this one.
