Which cart works with Ortofon AS309S 12inch arm

I have the 309D on my TW Raven one and have used a benz Micro LP and Koetsu Onyx. Both gave great results, the Koetsu is not supposed to be a match with the Ortofon, using arm cartridge compliance matching charts, but it sounds great to me.

anyone here know what the arm mass ofthe as309s ?

I found it very difficult to find out. The UK importer sought advice from Ortofon for me and even then it was'nt clear. I think the conclusion was 14 to 15gm, but I asked a while ago

Arm mass for AS-309S is 3.5-4g without headshell.

The Ortofon 2M Black might be too compliant for this arm... If you use a really light headshell (6-7g or less) you might get away with it.

Not sure about the Shelter because the compliance ratings aren't easy to come by.

Bottom line, this is an arm best suited for the stiffer variety of moving coil cartridges, including SPUs. Cadenza and Kontrapunkt series should work fine here also.

Full disclosure, I work for the manufacturer. Just wanted to help!

Effective mass of 3.5-4 grams without headshell makes absolutely no sense to me on this arm but I could be wrong.

If I am not mistaken, Jelco makes these arms for Ortofon and the 9" version of the arm most closely resembling the 309S with Jelco's stock headshell (12 grams) is 20 grams. Add another 3" of arm tube and I cannot see how this arm would not have an effective mass with the stock Jelco headshell of much less than 23-24 grams and even more with the SPU headshell.

As I say, I could be wrong.
