Technics headshell weight/ Audio Technica 440mla c

Thanks Fleib; I've looked at your contibutions and I am impressed by your knowledge in this area. I note the Technics 1200 arm has an effective mass of 12 g. as does the SME 3009 II, non improved. Does this mean that by simple subtraction both arms have effective masses of 4.5 gms WITHOUT headshell, as both the original SME headshell with wires and the Technics 1200 with wires both weigh 7.5 gms?? I find this interesting, as past implications have been on this and other forums that SL 1200 arms are heavy, when in reality they are the same effective mass as the 3009II, often thought of as optimal with high compliance cartridges such as th Shure V15III!

Hello Fleib: I got data from Ortofon that their 110 tonearm weighs 3.5 gms. without headshell. I assumed you could simply add the headshell weight to that value to get the tonearm Effective Mass, from which you could figure resonance, etc. How does Vinylengine figur effective TA mass on tonearms with detachable headshells? By the way, I just got my Virtuoso back from Soundsmith, and placed it on an unmodified Technics SL 1300, in the same cabinet I can play off against a Rega RP8 with an Ortofon Cadenza Red. I'm dismayed to say that the old Technics may better the new Rega for thousands less$$

Hi, Fleib; your expertise is greatly appreciated; much of your advice has already been implemented, and much of it will be in the future. You have answered and resolved many mysteries I have had over the years, for which I am grateful! To have access to someone like yourself makes membership in Audiogon truly worthwhile, in my opinion!
