Lew,
Raul prefers to 'imagine' his own physical universe, free of the complications of science.
He says that he's always willing to learn...but that's untrue.
First he states that the Resonant Frequency of a tonearm/cartridge combination should be 8-10Hz and then attempts to explain 'why'
He obviously has no tertiary qualifications in physics, materials' science,
structural engineering, mechanical engineering or acoustical engineering, yet continuously postulates false information as if they were 'facts' without ever presenting scientific evidence for his delusions.
Because he can hear an undamped metal tonearm 'ring' when he taps it....he imagines that this 'ringing' must occur even when he doesn't tap it. A mistake only made by the uneducated.
Not only doesn't he present evidence to support this absurdity....he can't even tell us the 'magnitude' of these imagined 'resonances', nor their frequencies nor where they are supposedly coming from?
His 'evidence' is always the claim of some contributor on a Forum or cartridge designer or reviewer with whom Raul agrees.
In the wake of his delusional view of the physical world and his real inability to listen to others and educate himself.....there is little point in arguing with him.
Inject into the cartridge pure tones that span the audio frequency range, say 20 to 10K Hz at log intervals, e.g., 20, 50, 100, 200, 500, 1K, etc, and at each single frequency, take a look at a spectrum analysis of the output. Absolutely no subjective judgement allowed.Too sensible and too scientific an idea to take root in this hobby...🤕

well, any resonance has fundamental frequency where happen that resonance ( it does not matters where it comes. ) and that means that at the same time that is happenuing are created its harmonics exactly as the harmonics in the music and that's why those " distortions " always affect all the listening frequency spectrum and we have to take in count that those " distortions " happen all over the frequency range not only at 8 hz or 20 hz but at 3 khz too ( for whatever reasons. .When I point out the absurdity of his explanation
And of course we all know that the harmonics of 8Hz (16Hz,24Hz,32Hz,40Hz,48Hz, 56Hz etc) do absolutely no harm to the tonearm in vibration mode whilst the harmonics of 7Hz (14Hz, 21Hz, 28Hz, 35Hz, 42Hz, 49Hz) render the tonearm a weeping sloppy mess..😱He conveniently ignores it.
