High vs low internal impedance cartridges....Is there a sonic signature for each type?

Is there a general sonic signature associated with cartridges that have either very low internal impedances, like the Air Tight PC-1 Supreme at 1 ohm vs those with high internal impedances , say around 40 ohm’s?
Of course each cartidge manufacturer tends to have a house sound, Koetsu- rich and midrange centric or LYRA-fast, detailed and neutral....., but that aside, does the internal impedance of the cartridge at either ends of the spectrum lend to a sonic signature as well?

The problem is about ''moving mass'' on one side and ''core'
versus ''coreless'' coils on the other. Reduction of moving mass is ''obvious'' by reduction of (wire) windings on the coil former. The lower the number the lower impedance but also the output. To increase the output ''iron core'' is usually used  but has as disadvantage ''magnets saturation''. That is why ''coreless'' coils are used.
This however reduces the output which causes phono-pre problems and /or the sense of SUT's use.
