For me is 8 hz to 10 hz the ideal resonance frequency. As a fact there is no rule about the precise frequency range.
""" No, it’s not about static. There is no resonance with static as the name implies. We’re talking about dynamic compliance, arm mass, and resultant resonance or affect on performance. """
sorry that I can’t explainit well. What I want it is to say that for that happen exactly as the resonance formula gives us we need a perfect LP recording with perfect LP surface. Yes the resonance frequency in a spring works with that formula, my mistake in the way to explain it.
Now, you really don’t know wich is the real tonearm effective mass in the tonearm because depend on the tonearm counterweight position.
""" No one is talking about that. """
maybe you did nt but the target to achieve that resonance frequency is to stay " save " from those frequency additional exicitemet.
Maybe I did it when I was a kid but that’s what happen with a metal non damped tonearm, it function as an additional resonance/vibration/distortions generator. Like it or not.
Maybe you are running that kind of distortion generator.
No it was not an anecdote but a proved fact by some one that knows a lot more than you and me together or at least than me.
Btw, B.Pisha was not a " simp’le " professional audio reviewer, he was a way talent engeneer that between other things created an alternative to Löfgren, Baerwald or Stevenson geometry set up tonearm/cartridge parameters that was reconized for the audio engeeering societies.
Anyway, what I think is that you have nothing on hand against my statement on: " heavy ,all metal non-damped tonearm designs " and only look where on my posts I made it a mistake and put " light " on that mistake.
IMHO, could be better that you can prove how is that a heavy and long all metal and non damped tonearm helps to improve the quality cartridge performance satisfiying all the cartridge needs and mantaining all the generated distortions at minimum.
This is what al of use like to hear from yu: a real contribution and not only to say: no, that’s the easy way. The right way is to say no and prove it showing why not.
At the same time we all are waiting why that tonearm is a good team for the Koetsu Rosewood and Denon 103R becvause you forgot to explain it: could you? because was your advise to wrm0375.
You are welcomed to do it. As I always say: we all need to learn and if I’m wrong then I can rectify about. Waiting for your in deep explanation with first hand experiences about.
Regards and enjoy the music,
