Ortofon tonearms ,Static and Dynamic - Difference?

To Agondgd,
Was interesting to read your remark as to
"static Ortofons are intented for the heavy SPU range of cartridges and Dynamic for a wider group of brands and models."
Then you stated it is vice versa. What interests me - I spoke with LDorio@ortofon today and he indicated exactly what you said initially - static for SPU and Dynamic for the rest.
Do you still think Dynamic has more narrow field of applications so to speak?
Thank you

I have an AS-309S arm on my TW Akustic Raven One, installed by Jeff Catalano of Highwater Sound in NYC-it was his demo arm and I got a good deal on it. Sounds very good-very clear and dynamic, picks up very little distortion, a little bit towards the warm side but then my whole system is geared that way because I'm very sensitive to steely treble. I had a VPI TT before the Raven, it had an Audioquest arm and this setup is leaps and bounds beyond it in every parameter. And its my understanding too that the designer uses Ortofon arms on the TW Austic turntables. Ortofon has probably been a little more popular in Europe since its an old Danish company.

I read that another thing to consider is how to get the counter weight as close to the arm pivot point as possible. I don't know the technical reason for this, but if all else is equal, the closer the weight to the pivot, the better the arm will sound. Perhaps an engineer can explain the reasons which I think have to do with how quickly the arm reacts to vertical movement.

I had a Shindo Labs turntable with a dynamic arm based on an early Ortofon tonearm. I think its outstanding performance was partially attributable to the dynamic arm. Once I tried it as a balanced arm. It was nowhere nearly equal to dynamic tracking.

I would just add to my comments about the 309D, that I made in 08. I am still happy with the arm, but found it was a poor match to higher mass cartridges. It really was'nt haapy with one of the stone Koetsu cartridges, much better with a Benz Micro LP. My fault for not checking compliance first
