I have an Audio-Technica AT15Sa cartridge without a stylus. I measured the resistance on the cart and it comes to 0.474/0.476kOhm. Would this cart be worth getting a stylus for? I am currently running Nagaoka MP-110 which I am happy with. Honestly, I do not really need another cart but since the AT was free, the only cost would be the stylus. But at the current price of $130 it is an expensive stylus. The Nagaoka was that for the cart and stylus. The stylus alone is about $60. Would I hear 2x improvement in sound quality? I know it is hard to say without auditioning but maybe somebody here has an experience with the AT15Se cart and can provide some insight.
