Is there usually a dramatic difference between $5k and $10k cartridges ?

It costs at least $10,000 retail to make a cartridge. Just as it costs at least $200,000 for an automobile. Anything less expensive is merely compromise for the poor.

Just like most things in HEA, at a certain point doubling the price will likely yield a 10% improvement in sound, but if you can afford it, why not?

At that level there is generally not a dramatic diffeence between any 2 components  You're chasing the last few percent.  that is not a bad thing.

Now people will get very excited when they make progress.  Lets do the math with some made up numbers to illustrate:  you're at 97%.  You find a component that moves you to 98%.  It is only 1% improvement but it got you 33% of the remaining and it is a big deal to you.

@noromance : $10K to make an excellent phono cartridge? Really? Let’s assume an engine for a BMW automobile costs $10K to build. I can understand that. Plenty of parts that must be machined to tight tolerances and then skillfully assembled by a team of workers. A phono cartridge is a small device that weighs several grams. I fail to see where there is $10K worth of parts and labor.

Are you using a SUT?

If so which one. I think a $5,000 cart with a great SUT would be better than a $10,000 without a SUT.
