another arm/cart question (long post)


Hello all. I've gotten some good advice here for 2 of my tables and would like to hear from the experts again. I've just built a Thorens TD124. Its got a rebuilt motor, main platter bearing upgrade with sapphire bearing and Torlon thrust pad. MK2 motor spring upgrade kit, Audiosilente idler wheel, new mushrooms and grommets, and an Ortofon plinth. New armboard on silicone O-rings, and a fully rebuilt, rewired SME 3009 series 2, unimproved, with an effective mass of 12.5g. The arm has the FD200 fluid damper kit, but its not currently attached. For an initial setup, I put an old Ortofon 540mkii on it and it sounds very good. In fact its close to my Sumiko blackbird low, and AT-OC9XML on my other admittedly lower quality tables/arms. Phono stage is the built in one on a Mcintosh C47, which is quite adjustable for MM or MC. It runs through 2A3 tubes into Altec A5s with modded Hiraga crossovers. Being impressed so far with the 124, I wonder how much better it can sound with a cartridge upgrade. I love my Blackbird and thought about a Starling, but am open to advice. My budget is only 2K for the cart and Ill need to purchase another headshell and wires, so maby $1800ish for the cart. I've studied the resonance charts and know that only gets you about halfway there. I don't have test equipment, only my ears. The chart shows a good match with the starling but Id love some advice. The last 2 times i sought advice here, I followed it with amazing results so thank you all for that !  Also I've raised the arm, and added a 3mm mat to increase the distance from the magnetic platter to the cart for when I upgrade it to MC.  I'd like to know if I will have a good combination with the Sumiko Starling, and if not, which cartridge would you choose ? Fire away !

Thank you for the responses.  I believe I’ll spend a little more time researching the art series.  The OC9 definitely has a great bass and I can’t imagine that improving. It was also very easy to set up and didn’t seem picky. 

I forgot to add that the arm has brand new, polished bronze knife edge bearings. I’ve read that these bearings can introduce chatter with certain cartridges, and that is why I opted for the fluid dampening kit if that helps

Yes the OC9 really improved my Dual 1229. I have been curious about the art series and wondered how much better they were than OC9. 

Opinions on the art9xA vs art9xI ? Shibata vs special line contact ?  Most of my records are new or newer. Many 180g. I don’t have enough experience hearing various profiles to have a preference 😵‍💫

This is all great information. I find that it’s not easy to search the threads when you don’t know what questions you are to be asking. Thank you all for contributing!

Yes I read about the .12 output of the 7, and wondered what that would equate to in real world application. I believe my McIntosh has 60db gain, with the ability of going up 6 more db in the trim settings. The lowest cart I have now is the 0C9 at .4.  I’m sure one day as I progress in the hobby I will get a stand-alone phono stage but I have some other purchases to make first. My spouse and I are both public servants so we have to budget for all of these purchases. Does anyone know how the McIntosh C47 would work with a super low output cartridge ?  I’d likely go for the 9 vs the 7 but I am curious about compatibility.
