Tonearm recommendation

Dear halcro: Exist no mantra. Your tonearms mistakes ( every one learned through each one mistakes. I learned through them too. ) are facts  but you still live with those mistakes and other ones that are facts and no mantra.

Please don't try to hide the sun with your finger because you can't.

You  bought that DaVinci " GREAT " TONEARM AND YOU WERE PROUD OF IT. It does not matters that you accept it that was a mistake an ignorance mistake.

Normally our mistakes are ignorance mistakes and some other comes by " accident ".

Enough, the thread does not about you ( be happy. ), me or even wrm0375 but looking for advise. and I already gave mine.

Regards and enjoy the music,

Dear wrm0375: Btw, looking for advise but seems to me that that was not your real target because you are happy with the mediocrity/average level of your tonearm and cartridges.

The advise I gave you was an unbiased one and looking for a real improvement of what you have today, looking for an improvement and that you can grow up enjoying a better audio/music experiences in your system but you have to have an open mind .

As I said that's only my opinion and the best one comes from you and if you are satisfied in your today status then stay there.

If all that is true then your thread has no sense asking for advise when you are not open to receive it and put wirth a defensive attitude.

Anyway, live with your choices. That's what deserve each one of us.

Dear fleib/chakster and friends: That advise that we need a high mass for a low compliance cartridges has many " roads " surrounded it.

Mantain frequency resonance value, between tonearm/cartridge, in the range of 8- hz to 10 hz is something that many of us always are looking and is something all of us want it.

In theory that’s the frequerncy range we have to look for and I say in theory. In theory that can gives the cartridge7tonearm better tracking and mantain at minimum bass resonances that has a huge influence in all the frequency spectrum during LP playback. I’m not questioning that theory.

Now, what happen during playing because the theory is on static way where the cartridge is not ridding the LP grooves.

Everything change during playing because the cartridge has to fight not only with the movements in the LP grooves but with the excentricities of the LP and its micro and macroscopic surface LP waves.
The theory of that cartridge/resonance frequency is that to low frequency like 4-6 hz cabn be exited and coincide with vibrations/resonances generated by the TT/cartridge and then can make that in some areas of the LP surface the cartridge/tonearm " jump "/mistracking.

Well, how the real tonearm designers fixed that real problem?, using engineering concepts and the main one that even today is a must in any tonearm design was to damp the tonearm to mantain in effective way those " terrible " resonances that always affect directly to what we are listening in the full frequency spectrum.

In the golden Audio magazine times ( 80’s. ) B.Pisha made a full review of the LOMC Ortofon MC 2000 ( I think 1984. ) that for every one is a learning review ( including for today professional reviewers. ):

things are that this cartridge is a heavy weight high compliance one. Pisha mounted in all Technics TT ( SP 10 ) and S-shaped tonearm and he measured during playback a resonance frequency of 5hz in between cartridge/tonearm and he started to listen diferent LPs with no problems at all and he said that because he can’t believe that the cartridge/tonearm with that so low resonance frequency could works so good he measured for second time and confirm that that resonance frequency was that low. He measured during plasyback a dynamic cartridge compliance of 31 cu!

That combination tracked totally clean all the cannon shots in the Telarc 1812 ( and other torture recordings. ) where you can find frequencies so low as 8 hz!!!

So what was happening? all that gone against the theory and believes of all audio experts, why?:

thing are that that Technics tonearm ( 250/100. ) has a self damping mechanism that just works marvelous, a mechanism that even today can be an envy for any single tonearm designer.

That is real science in tonearm design but Technics was and is part of the electronic gigant japanese corporation: Matushita, where the research and work is not made it for one person but for dozens of them where there is no resources limitations.

There are other old examples of great engineering tonearm designs as the Lustre GST-801 and others.

As I said the all metal FRs are because of that metal a natural/self resonace/vibrations generator device but along that is a NON DAMPED DESIGN!!!! go figure.

There is other critical problems with high mass and long tonearm designs:

The main target in a cartridge is to follow/ride perfect the LP grooves and for that the cartridge tracking is a constant in horizontal/vertical fast movements where the tonearm has to react in the same faster way to those cartridge movements.
Now, during playback exist an inertia to the cartridge/tonearm to the center/inside the LP that inertia goes per se against the cartridge ride and the tonearm needs to control ( but has not that control in any way. ) that inertia movement/force and here as higher is the dynamic mass in a tonearm as higher is the dificult to change that inside inertia when the cartridge rides to the opposite path.
Always is easy to " stop " a lighter dynamic mass than a high mass device.


So and IMHO we need very good damped tonearms with no high effective mass.

You can think what you want and stay happy with what you want but those are facts. I learned and time to time all of us can do it if we want to do it.

Because it's made by someone who actually knows something about audio instead of someone who is a pretender....

Still there seems to be no limit on pricing of these products. It has really no relevance to the actual cost or research. I mean it isnt a lifestyle product which has to be priced into a "untouchable" territory
