The 1/2 inch mount is standard, around the world. The only thing that won't work is mounting a cartridge with threaded holes in the top to a headshell with threaded holes on the bottom, and there are few of those any more.
Trying to get as high a compliance as possible with a particular tonearm is like trying to put as soft a spring as you can in a car. It does not compute.
What arm do you have, and which cartridges are you considering?
Thank you very much for your answer.
I asked for advice on a cartridge for a Technics SL-Q202 turntable with a 11g relative tone-arm mass. I got the advice that said Audio Technica should do fine and that it is an all around performer that can do various music styles to a certain degree. Not being able to read Japanese numbers for compliance, I didn’t know that the resonant freq. I got was a rather low 8.33 and that this cart might do well on perfectly flat records, but I don’t have many of those.
Sure enough I got the woofer pulsating with long, slow excursions.
I was convinced I got a good cart so I started worrying that there’s something wrong with my TT. I thought suspension, I thought platter friction, I thought acoustic feedback. I did a hundred tests and finally took it to the shop. Nothing wrong with the TT, I got a mismatch in tone-arm / cart resonant freq and it is augmenting the pulsation in the cones. So I want to move away from this range of 8-9Hz maybe closer to 11Hz.
There were three ways we calmed the cones down, the repairman and I; flat record, subsonic filter and a different cart.
Notice, when we replaced my cart for another one, the speaker cones had no pulsating even without a subsonic filter. I’d say that’s just a better match, but that was a very old Ortofon cart they don’t make any more so I couldn’t just buy that one.
Original cart specs for this TT said 10x10 but this is measured at 100Hz and I can’t find any reviews on the original cartridge (we haven’t got this one in VE database).
As a rule of thumb, one would calculate that 10x10 at 100Hz is 17.5x10 at 10Hz and the AT would be 12.25x10
The way I posed the question was; I know I shouldn’t go to high with compliance for a 11g tone-arm and all the calculators reassure me of this, but I’d like to go as high as possible for this specific tone arm without overdoing it.
