"Peddling woo to vulnerable audiophiles"
I'm touched by your concern for our sensitive selves, and presumably our pocketbooks. Be assured however that those of us that take the time to listen to a lot of cartridges and put our $ where we want can hear very substantial differences between different manufacturer's offerings and different points in the line
As others have pointed out to get the most from any cartridge setup and matching is absolutely critical and if you are going to spend four figures or up on a cartridge then you owe it to yourself to know how to set it up, and to invest in the tools for that purpose.
So I'm not at all sure where your strong online sentiment is coming from -- presumably from those who have never had the chance to spend a substantial amount of time with one of these transducers in their own system with commensurate ancillaries
For your delectation I leave you with the following link -- a review of a $12,000 dedicated mono cartridge, and personally I can believe it's worth it ... makes my $2K mono feel jealous
