Cartridges: Complete Scam?

I’m very new to analog, and researching my options on forums I keep coming across the same sentiment: that past the ultra low-end cartridges, there is very little gains in actual sound quality and that all you’re getting are different styles and colorations to the sound.

So, for example, if I swapped out my $200 cartridge that came with my table for a Soundsmith, Dynavector, Oracle, etc, I may notice a small improvement in detail and dynamics, but I’m mostly just going to get a different flavor. Multiple people told me they perffered thier old vintage cartridges over modern laser-cut boron-necked diamonds.

It’s possible that these people are just desperately defending thier old junk and/or have never heard high end audio. But if what they’re saying is true, than the cartridge industry is a giant SCAM. If I blow 2.5k minimum on an Air Tight I better get a significant improvement over a $200 bundler — and if just all amounts to a different coloration, than that is a straight-up scam ripoff.

So guys — are these forums just BS-ing me here? Is it really a giant scam?
