Low Mass Arm and Mono Cartridge
My turntable uses a Signet XK50 tone arm. This arm has interchangeable wands, so I thought it would be great to get a mono cartridge and mount it on one of the wands. This way I'd be be able to go back and forth from stereo to mono in just a minute or so, with only a re-balancing needed.
The problem is that this is an arm with a low effective mass. I don't know the exact figure, but it is less than 10 grams. As a result, a lot of cartridges don't work well with it. Shure V15- cartridges are OK, for example, but Grados are not (requiring an arm with effective mass of 12-17 grams).
I see that Benz in now making some of their cartridges available in mono form, and a new Dorian mono is on the way. Perhaps other things are on the way. But will any of them be compatible with this low mass arm?
