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,

Raul use to fix his tonearms with chewing gum. They were in dire shape and the chewing gum made them sound better. Is why he likes damping.
Next he'll tell you that he like Double Bubble best. I'm a Wrigley guy myself.

noromance - there is major difference
750 - ball bearings
850 - knife edge bearings
if to look into all knife edge bearings - SAEC, SME and new Jelco series all of them looks ok without extra damping.
Ikeda/FR uses spring  + weight for that purpose
Dynavector uses magnet
Alfred who modifies cheap Ortofon tonearms from the past uses balsa inside the tube


Raul, all the clowns I know are really nice people. Pretty smart also.
I think you do them an injustice relating them to ignorant. 
@rauliruegas,

You and @lewm have it right - every application is different.  Its more than the just the cartridge and its compliance.  There is a decent article on tonearms in this Audio Magazine https://worldradiohistory.com/Archive-All-Audio/Archive-Audio/80s/Audio-1980-06.pdf, and as stated in the magazine - all materials have some damping capacity - https://sites.utexas.edu/taleff/files/2019/10/jmatersci_v28n9y1993p2395.pdf.

The tonearm manufacture is literally between a rock and hard spot trying to design a tonearm for the multitude of table and cartridge designs that all together form a resonant system.  But, as has been stated, if your cartridge has the option for viscous damping then it may be worthwhile trying - but its success aside from table/cartridge could also be music type - maybe good with classical but not with vocals.  All the more reason for multiple arms and/or multiple tables LOL.

Just some thoughts.
