Dear @cleeds : Maybe @br3098 is refering that near the fulcrum makesthe tonearm has more operationsl stability but agree with you about modified the effective mass.

Dear friends @lewm : as I said to complicated to be really precise or to achieve/have numbers in the subject because exist several parameters to take in count during play and we have to remember that even if we can't see the cartridge bounce all happens at microscopic levels and no matters what numbers says we really don't know what is down there happening. Cartridge has its own resonance frequency between the: cantilever/stylus and the fulcrum in the suspensiion where the cantilever is atached. The next thread is interesting for the gentlemans that want to confirm what they already know or that want to learn a little more on the subject: http://www.vinylengine.com/turntable_forum/viewtopic.php?f=18&t=78564#:~:text=Principle%3A%20To%20measure%20actual%20tonearm,effective%20mass%20of%20the%20tonearm.

" Your comment would leave me to believe that you have never set up a cartridge correctly. " You have no idea what you are talking about and this time as almost always your opinions comes from your imagination are what you figure about with no true foundations but your own experiences that could be some wrong because your misunderstanding on " something ". Do you think you own the audio Bible? Sorry, no one has it and forgeret about that LP test and re-read what I posted to you because I think you are way wrong if think that even with vaccum hold down that LP test is PERFECT. R. |
Dear @lewm : obviously that a tonearm as a cartridge in static way has no intrinsec resonances but in the very first moment that the TT spins even with the tonearm in rest that tonearms has " resonances/vibrations " at micro levels. So @bdp24 is rigth about. The overall subject always been a little controversial because the formula calculates the resonance frequency of a cartridge/tonearm at static/rest way. The numbers are the ones from those combinations of tonearm-cartridge and it’s a good place to start with the subject but those numbers will change during playback because exist additional parameters that affects it. Yes, the formula says what you posted but you have experiences where that not really happens during playback because you love that very heavy FR tonearm with a cartridge boarding in the 40-50 cu and you love that combination. So, some one out there needs to model what in reality happens taking in count all those multiple factors/parameters around this controversial subject. Even those always is convenient try to achieve the ideal frequency range in our tonearm/cartridge combinations because the quality performance will be better than if we don’t care about. Problem is that several times we like what is wrong and dislike what is rigth ! Btw, """ supplying a set of CWs that vary in mass . "" this was posted too by @bdp24 with his Zeta tonearm but is not critical inside the resonance formula because the CW is near the fulcrum and contributes very low for the total mass. What is important for place/position the CW the nearest we can to the tonearm bearing is to gives to the tonearm a better overall " displacement/operation " during playback, give an additional facility to the tonearm work.

Dear @mijostyn : "
Use the darn record! " Really, because exist no perfect recorded LP and in that so imperfect medium with so many different parameters involved and full of resonances/vibrations/noises/distortions developed how can you trust in what is supposed to be measured ! !
