it is the same all over audio and many industries, High performance comes at a price, but to get beyond that, the cost can be astronomical...
You have a car that will run a 1/4 mile in 14 seconds, you drop $1000 in the engine and get it below 12 seconds, you need to drop another $3000 to get it below 10 seconds.... how much to make it even faster?
The tweaking and expertise to get better performance in a phono cartridge is no different....
a 12 second 1/4 mile car is fast, but is it worth an extra $3000 to get a 10 second car?
Of course the numbers are just arbitrary, but the concept remains true.
So, no, its not a scam, but minor differences in performance are expensive.
