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.

Spring loaded anti-skating mechanisms actually provide some damping. I prefer my fluid damped arms, but the engineering is the real key.  I added a bit of very thick fluid to the "razor" bearing of a pal's Grace 707, and it did smooth it it a bit.
Merely being able to play an LP side without skipping or obvious distortion is not itself proof of good tracking.
An oscilloscope has been indispensable in our mastering operation. Test equipment can be quite handy for moving from anecdote to more fact-based findings :)
A spring oscillates like the rubber spring in a cantilever the silicone acts to control the oscillation- I understand that it controls’velocity’
Well @rauliruegas 

I tried the FR64s with the trough.
My audio chain:
1. Modified Townshend Rock Elite
2. FR64s arm
3. Monster Sigma Genesis 2000MC
4. Cardas Golden Reference phono cable
5. Lavardin IT amp
6. DNM speaker cables
7. Roksan Darius S1 speakers

I have this in a nearfield set up.

I used 10,000 cst silicone oil which i understand is lighter than the standard oil weight. 

I had a short listen to the FR64s and thought it sounded perfectly good - though I must say the image precision was a tad lacking but it had plenty of gusto.

I stuck it in the trough and the transformation was very clear. At first you think images are smaller - in fact they are far more precise and occupy spaces much better. In addition to this surface noise comes down and bass was more preisee to my ears
Dear @billstevenson  : "  While you seem satisfied with you methodology, I encourage you to try and borrow an "O"scope because I am sure you would like it. "

Yes, maybe I like it.

Bill I don't want and don't need to go so " detailed " on the cartridge tracking issue because could be useless at the end other than " curiosity ".

You can be sure that my whole tests process with all my choosed LP tracks tells me all what I need and if you tested my finding through an " O'scope " you will find out that I'm in the " road ".
The key there/in the process was and is its methodology and those choosed tracks and to know at 100% why choosed those tracks and no others.

Anyway your advise is welcomed but remember that we ( at least I. ) are just audiophiles.
