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,

Tonearm damping is a bandaid for poorly designed arms or turntables and/or mismatched arm/cartridge.

In my experience with many arms, even those with damping facilities provided, the application of fluid damping slugs the sound, particularly in speed and resolution. 

The original Excalibur arm was plagued with bearing issues. I know this because I used to sell the Elite Rock's. I still somewhere have a hand written 2 page letter from Max Townsend on how to fix them. The fix was not permanent though - there was a design flaw in the arm bearing.

Funnily enough for a few months I ran my Eminent Technology air bearing arm on the Rock with no damping and it was excellent - far better than with the Excalibur/trough.

 

says that is the best ever tonearm arm wand by its rigidity and low resonant figures but the Technics EPA 100MK2 was and is in reality the best one about by its boron arm wand that has better characteristics than sapphire 

Wrong.

The Technics EPA 100MK2 is predominantly a titanium arm tube with a boron coating. Titanium is not rigid, it flexes, you can bend a titanium tube with your bare hands. How do I know this - I use to work for the largest manufacturer of titanium tubing on the planet.

On the other hand the high mass of the Safir would be a concern to me.
