I have used 3 cartridges over the last 40 years and I am the original owner.They are:(1)Empire 1000ZE/X. Needs new stylus. (2)Pickering XL-33U. I have two Pickering DTL-2S stylus for this cartridge with all original packaging. (3)ADC XLM MK III. I just bought a new,authentic ADC stylus for this and I'm having the cartridge mounted. I have been told the ADC is the best of these 3 cartridges. What do you think? Which is best? Which should I sell? Which should I keep?
