Reply to So whats the deal with head shells?

Okay so ive asked around some people that i know and I cant really get a straight answer:

whats the difference between head shells? aka is my stock stanton t.62 headshell any better or worse then my stock sl1200mk2's and would it be worth it to even look into changing them? does weight (12g over 8g for example) even matter for me if im not an audiophile and even if it did im balancing the tone arm anywho no matter what the weight is.

basically what im asking is to school me on head shells man. educate my ass
