Why do better MC cartridges cost a fortune?


I mean $5k - $10k for a piece of what? I can understand $10k for a turntable but for a tonearm or cartridge?
They charge and we gladly pay? And you have to retip or replace it soon enough. Most of them come from Japan. They sure know how to do business, don't they?

Even so, any decent cd player will be superior. Turntables are just money spinners for the trade, and if you are like me and you like mechanical engineering, they are also nice toys.
We are not talking about cd players, you might've lost the direction a little bit.
inna,

Assigning relative cost structures to equipment is ludicrous. Results vary widely regardless of price and are instead tied to educated equipment matching and proper setup, especially with turntables, tonearms, cartridges, and phono stages.

One does not contradict another. What you said is obvious and that's why I didn't even mention it.
Yes, I hear enough people putting $3k cartridges on $3k turntables and playing them thru $2k phono. This will not be bad, this will be stupid.
Everything is stupid at its extreme. These threads you start seem to be aimed at generating contempt toward those that can/do spend a lot of money on audio.

I, like many here, don't have that kind of money but have instead spent many years and countless hours assembling an audio system that is not defined by such identity bias.  Maybe start some threads on how that is done...
