Excuse me for bringing this thread up, but I just got my hands on an ADC QLM30 mkIII cartridge (nos). I tried it on my Technics SL1200mkII and it sounds very good! Soundstage is huge and the sound is detailed and crisp. I'm really surprised by the performance from this one. However, my cartridge came in a private market boxing, with neither any instructions, nor specifications. I did some looking around and it seems this wants to track at 3-5 grams. Correct me if I am wrong. What I was unable to verify, is the output from this cartridge. Just by listening to it, seems to be on the lower side of things. From experience I would guess it's around 3mV (@5cm/s)?? The few specifications I 've found online, are all over the place. Anywhere from 1mV (@5cm/s?) to 7+mV. I am puzzled... Any help would be appreciated. Thanks.
