did the Mark 1 not have a bit of a massier tonearm..??
I imagined that when someone says SL-1200 that most people assume its the M2K so I left that part out. My table is indeed the SL-1200 MK2.
I went ahead and tested the M44E and M447 cartridge bodies with the same stylus (brand new N447) and the same album, my findings were rather interesting. The M447 body produced a rather dark subdued sound while the M44E body is bright, full, and energetic (mind you all testing was done on the same table with the same setup and alignment applied to both cartridges). The only way I can simply describe the difference is to say the M44E sounds like a light blanket was lifted from the sound of an M447.
I've prepaired a sample of both cartridge bodies (again same N447 stylus). M447 cart was recorded first.

I'm hearing a little difference myself..Interesting..
The sibilants are a little less forced on the 44E body.
I think things like inductance could differ a little in production..
I've noticed myself a new cartridge body can sound a little different than another example of the same..I guess older production wasn't as consistent..
So possibly the difference could be more marked..
Maybe it was more consistent by the time your cartridge was made though..
Many theories there and I don't want arguments to start..lol.
Wire burning in,,magnets weakening slightly..etc
Back when Gibson wound PAF guitar pickups without precise automatic counters etc..
They would all come out different due to inconsistent winding..
A bit more or less windings..
Different wiring suppliers,or even more inconsistency in the wire..
Or the magnets used..
The modern 44 7 may not even use the same wire or magnets..
The Gibson PAF pickups would all end up sounding different..
Could be a case of this here..
Strangely,,so many people claim to sell an exact replica of a PAF..
The original PAF's are highly prized and expensive..
They use sand cast magnets and wooden spacers etc. in replicas..
All the original PAF pickups sound different though.
So a replica,,which one is it a replica of.
Guitar pickups sound different as they age too, partially due to the magnets weakening..
PAF stands for Patent Applied for by the way..
I also read somewhere,,can't verify though that Shure used Alnico Magnets back then...
Alnico tends to demagnetise over time..So it could be that..
Again with guitar pickups,,some folk swear Alnico sounds clearer..
The newer 44 7 may not even use Alnico magnets..
It may use thicker wire,but less turns..
Or possibly a combination of everything above could be the cause..
