I do not agree with this rule at all. Tried a few respected (brand new) $3000-5000 MC cartridges on high value various tonearms and returned to the rare vintage MM cartridges with ease. First any MM cartridge is always much cheaper than MC, but the quality and sound is not "cheaper". This is not universal rule, but carefully selected top vintage MM cartridges ara amazing and still 5-10 times cheaper. Apart from the vintage cartridges the only vintage things in my analog rig are the nos tubes, direct-drive turntables and toneamrs. I will never spend $3000 on any cartridge again and it does not make big difference to me like it makes to you. However, the cartridge is the most important component in my opinion and it’s worth to try many of them to find the one which gives us tonal satisfaction, but it is not about the price as you described it (it's about the search). $10000 for a cartridge is a nonsense, let’s face it (and don’t tell your wife). Anyone is able to build the decent sound system without spending $10000 on a cartridge. Don’t forget the used market offers, $1500 for MC and under $700 for great and very rare MM and that’s amazing deals for superb cartridges.
I will completely disregard cart/tonearm/phono synergy and compatibility issues and give you the most honest answer that I can, having myself bought and/or experienced a variety of cartridges ranging from U$200,00 to U$10,000: YES, IT MAKES A LOT OF DIFFERENCE and the upgrades are not subtle, but rather like "I CANNOT live without this improvement". I wanted to believe that there’s no difference between a thousand dollars cartridge and a four thousand dollars cartridge
