High End cartridges and the built quality

I got 99 problems but a high end cartridge ain't one.
Big up JZ! ;^)

And you wonder why different people have different opinions about the same cartridge! Now ya know!

I have always suspected that the sample to sample difference between cartridges of the exact same brand and model can be about as large as the difference between one of those samples and that of an entirely different brand and model, given both are similar in electrical parameters and stylus shape.
