At what price point do I run into diminishing returns on an MC Cartridge?

I need to replace my MC cartridge.  I've had limited experience with them but I have certainly noticed a dramatic difference in performance.  My first 3 were priced at $500 Sumiko, $900 Ortofon and $5000 Linn Kandid.  The difference between my first cartridge and second - nearly double in price, was a very noticeable improvement.  Then I took the plunge and spent $5000 (after tax) for my Linn Kandid cartridge.  The difference and improvement in the quality of sound was startling.  The soundstage was like nothing I'd ever heard before.  Coupled with my newly acquired McIntosh MP 1100 phono pre-amp and I was hearing things in LP's that quite frankly I had never heard before.  Amazing!  So here's the question: At what price point do I run into seriously diminished returns on a cartridge investment?  I rather doubt I'm going to have "double" the quality of sound that I received with my Linn Kandid cartridge if e.g. I went up to a $10K cartridge. So, my question to you audiophiles with loads of experience, what is your opinion on what price point (neighborhood) would take me to a place where every dollar spent thereafter would yield only micro returns.  Said another way, what is the best price point to take anyone to the the same neighborhood as a person with "money to burn" on cartridges?  BTW, I realize there are probably some pearls that don't cost nearly as much - and that money doesn't always buy you love.  If you KNOW of those do tell.

@grgaudio Good post, which I agree with mostly. However, I do not agree with your estimates of cartridge life or the fact that a low quality diamond( what is that?) will last less than a high quality diamond. IF you are saying that a superior shape of the stylus will incur less wear through time than an inferior stylus design...maybe. Also, I do not think that your estimates of damper (dampher??) life are at all accurate. Simply due to the numerous variables on how cartridges are a) treated and b) designed and c) subjected to climate conditions. Most cartridges that I know have damper life that far far exceeds three years...assuming that they have not been left in either the freezer or under a heat light, LOL.
Oxidation will occur over time...but again that can take many years to occur...if treated correctly.
OTOH, some of the vintage cartridges that have dried up and worn out decades ago will indeed do one thing...ruin your records!

Daveyf,

The styluses have different configuration. Conical stylus has one face. The sophisticated Shibata or Micro Ridge like have up to 32 faces. To mount and align such on a cantilever takes laser beam technology to get the angles right. When using, any mis- guidance or mis-aligning damages the original shape quite fast and easy.  All styluses diamonds are lab created and polished these days. Also, some cheap styluses were made of ruby/sapphire like composite or different corundum composites. Sometimes they were good for just 100-200 hours.

You are more than welcome to believe in long life of damphers because you have experience and hear it right. We test these with proper devises, have results and I stand behind my words.

@grgaudio Do tell how you test dampers --er.. damphers?
Styluses do indeed have different shapes..configurations, and the cut can have a connection to the length of its life, but that is nothing to do with the quality of the diamond, simply to the wear pattern of the shape.
BTW, there is no conclusive evidence that I have ever seen that actually truly shows wear patterns on the surface of the diamond after x number of hours. Not saying that the stylus does not wear out, but there is no predictable pattern of wear regardless of the shape.

Daveyf,

 We test damphers in laboratory here in USA, In Europe and home. There are many instruments to do testing. Some are simple and we can do this at home. Some are very sophisticated- we do lab tests.

All lab created diamonds are different quality. Different polishing quality too. The worst are G from Europe, The best are A from Japan. There are some in between.

Most of users never understand how stylus reads the grove and stereo grove in particular. In few words when stylus wears it becomes more dull and bigger surface/diameter. It does not go as deep in a groove as it used to and not scanning the vertical groves well. So the more stylus wears- the more mono you hear. Some report this as dullness, some hear distortion, some say the cartridge don't sound fresh and musical anymore.

@grgaudio  Interesting hypothesis you have there. Damphers ( not dampers??) tested in your lab...:o)
