FR64s & Orsonic Av-1s Effective mass ?
Hi lewm I have already tried the combo, original fr64s/ Decca Super Gold, and it is playing music in a way. Vinylengine calculator with fr64s original headshell ( 35 EM) says around 7.5 hz. I am also using the " Decca pod" that adds maybe 5 grams. ( Do not have an accurate weight here that exceeds 5 grams now). But when I tried the arm/ cartridge compability track at Hifi news test record the cartridge jumped straight into the next track:) About the resonance track on Hifi news test record, I read somewhere that the results/ cutting actually is wrong!? I also have an Ortofon test record I can try on later.. Your trick / calculate formula seems interresting. But if it is as easy as Raulirugas is saying...? |
I don't know where to begin. If VE says that the OEM FR64S + its OEM headshell have together an effective mass of 35g, that's a good place to start. Then you have to add the weight of the cartridge and the screws and nuts used to hold the cartridge in place. But you'd like to know the weight of the OEM headshell separately, so as to be able to compare it to the weight of the Orsonic, like Raul says. And even then, the change in EM is not the same as the difference in static weight of the two objects. (I don't know what a Decca pod is. Perhaps it's something that goes between the headshell and the cartridge. If so, the pod plus Orsonic might be close to the same weight as the OEM FR headshell. The difference would be negligible, IMO.) If it sounds good, especially in the low bass region, it probably IS good. If the calculated resonant frequency is 7.5Hz, that is not so bad either.
