I'm afraid that a person who advice you to use any cartridge with Elliptical stylus like your Sumiko for 1500 hrs know nothing about stylus life span and the difference between stylus profiles such as Elliptical (one of the cheapest and simplest) and advanced profiles like MicroRidge and related. Only Micro Ridge can be used for 1500 hrs while the Elliptical profile will be dead after say 500 hrs top !
If it easy to check. Just learn a bit about life span of the styli, it depends on diamond profile.
If you're using your Sumiko for more than 500 hrs you will damage your records soon or already damaged it. How come anyone can expect 1500 hrs from an Elliptical profile? Even Shibata can't be used for such a long time.
