TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ?


Dear friends: This tonearm critical subject sometimes can be controversial for say the least. Some audiophiles swear for non damped tonearms as the FR designs or SAEC or even the SME 3012 that is not very well damped in stock original status.

Some other audiophiles likes good damped tonearms.


In other thread a gentleman posted:


"  If a cartridge is properly matched to the tonearm damping is not required. " and even explained all what we know about the ideal resonance frequency range between tonearm and cartridge ( 8hz to 12hz. ). He refered to this when said: " properly matched to the tonearm ".


In that same thread that a Triplanar tonearm owner posted:


" This is the one thing about the Triplanar that I don't like. I never use the damping trough...... I imagine someone might have a use for it; I removed the troughs on my Triplanars; its nice to imagine that it sounds better for doing so. "


At the other side here it's a very well damped tonearm:

Now, after the LP is in the spining TT platter ( everything the same, including well matched cartridge/tonearm.  ) the must critical issue is what happens once the cartridge stylus tip hits/track the LP grooves modulations.

The ideal is that those groove modulations can pass to the cartridge motor with out any additional kind of developed resonances/vibrations and that the transducer makes its job mantaining the delicated and sensible signal integrity that comes in those recorded groove modulations.

 That is the ideal and could be utopic because all over the process/trip of the cartridge signal between the stylus tip ride and the output at the tonearm cable the signal suffers degradation (  resonances/vibrations/feedback ) mainly developed through all that " long trip " .


So, DAMPING IS NEED IT AT THE TONEARM/HEADSHELL SIDE OR NOT?


I'm trying to find out the " true " about and not looking if what we like it or not like it is rigth or not but what should be about and why of that " should be ".


I invite all of you analog lovers audiophiles to share your points of view in this critical analog audio subject. WHAT DO YOU THINK ABOUT?


Thank's in advance.



Regards and enjoy the MUSIC NOT DISTORTIONS,

Dear @atmasphere  : In reality the resonance frequency between cartridge/tonearm is not affected because the tonearm EM change is really low because the kind of damping that we are talking about contributes all over the arm wand and not at the headshell only that's where matters more.

You can measure/calculate, here an example: EM 12grs. and with a 12cu caRTRIDGE with 8gr.-12gr. weigth you are inside 110hz and if the EM change to 15grs then it can change to  at 12grs. 9hz but at 8grs. stays 10hz.

I found that adding the Sumiko Analog Survival kit meant that I had to use cartridges with a bit lower compliance. IOW while solving one problem another is created, like many things in life. A better solution is to start with a properly damped arm tube.
@atmasphere  : the dronepuck advise or even that 3m electrical tape or any other ligth tape makes almost nothing for the tonearm EM goes higher enough to be a problem.

Yes, the ideal arm wand should be very well damped but that is the ideal/perfect arm wand that does not exist and that's why we have to take some actions about.

Dear friends: As I said before the silicon paddle mainly is to damps the cartridge ridding more than the tonearm it self. The " tape " is for the tonearm and inderectly benefits the cartridge transducer and its ridding through the groove modulations.

Townshend understand it very well: main subject is to helps the stylus tip ridding, this is the critical issue.

For all the information in what different gentlemans posted here we can see that the stylus tip not always is in perfect touch with the LP surface but several times is jumping and not touching the LP surface, something similar of what happens to a snow skier that due to acceleration and the snow imperfections is not always in  firm touch with the ski bottomplate..

Silicon paddle objective is try that the stylus tip stays " all " the time in touch with the LP surface along better control over the off-center LP characteristic as the macro and micro waves imperfections that disturbs a lot and creates vibrations that the transducer takes as if were groove modulations and reproduce it incrementing the distortion levels, any kind of developed distortions.
From that point of view, like it or not, the silicon paddle is a must to have, we need to help the cartridge ridding. As other gentleman posted here it improves the tracking cartridge habilities and this is a fact that I experienced several times ones and again and again.

Improving cartridge self tracking habilities means lower distortions, more true and complete signal information and improved quality level performance of what we are listening.

I have to say that's really dificult to verdamp not only the cartridge ridding but any other ling in the room/system but the room that's very easy to overdamps.
I'm not saying that we can't overdamp the cartridge/tonearm because we could when our kind of damping impedes the cartridge/tonearm " free " ridding.
Damping must be enough to the cartridge can has more control following the groove modulations, exactly what an skier is looking for during its fall in the mountain or through obstacles: control.

So one thing is to daps the tonearm and other the cartridge and we need both kind of damping down there it does not matters the way we try to do it: we need it, some way or the other.

What do you think?

@rauliruegas 3M and a few others make a butyl rubber tape that sticks to itself when you stretch it. I've not compared it to the Sumiko Analog Survival kit but it does work and does not leave a sticky mess when removed.


The Triplanar has an internal damping mechanism in its arm tube and so works well lacking any external tape for damping. In this regard it works better then the SME5 with damping while at the same time having lower mass.


BTW I think you mean 'riding' when you are using 'ridding'. Riding is used like 'riding your bicycle', 'ridding' is used like 'getting rid of garbage'.
