But what ever cartridge you buy the ultimate sound you are able to get out of it depends on the tonearm and its support or turntable . Best sound quality for cartridges are in the moving coil camp which normally are low compliance so if you go with moving coil you would need a at least a medium mass tonearm and a high mass tonearm as best option .
Not every Moving Coil cartridge is low compliance, Dynavector KARAT series are not low in compliance. Most of the modern MC are mid compliance. There are even high compliance MC cartridges from the past like the Ortofon MC2000.
Also not every MM or MI are high compliance, they are mid compliance, some modern like Nagaoka are even low compliance. Vintage high compliance cartridges from the 70s are still the best and bests many modern MC.
So mid mass tonearm and mid compliance cartridges is mainly what we have today on the market.
