I've tried that particular combo and it's not a particularly good match. The Karat Ruby seems to be happier in arms with higher mass and rigidity.

The arm/cartridge bass resonance was too high and there were a lot of midrange colorations from the cartridge dumping energy back into the not-so-rigid arm. My favorite matches with that arm were the Shure V15, Technics EPC205C3, and Grado G1+, but they're all discontinued- this was 20-25 years ago.

I don't think it's a matter of mm vs. mc, it's finding a moderately high compliance cartridge that doesn't need the arm to absorb much vibration. I haven't tried the Audio-Technica 150MLX yet, but on paper, it looks like a good candidate (it's MM). The Ortofon MCs also might be suitable- one of my friends uses one (a Rohmann) in a relatively light unipivot arm and is very happy with it.

Thanks,

You know that the grace f9e and supex sd 900 have 12cu compliance--it's medium to low compliance and both were a very good and musical match to the grace! (indeed both have a low
mass--around 5-5.3g)
