The arm mass is still important when matching any cartridge. Many people incorrectly assume that all S-arm turntables have around the same arm mass. Some are heavier or lighter than others. My old JVC has a 21g mass tonearm (more with an aftermarket headshell), much heavier than an old Technics. One of the reasons the last cart I bought for it was a Goldring 1042 is because that cart has lower compliance and is a better match for a heavier arm than others.
