Can an old Thorens Table be "Over Dampend" to the point where sound is adversely effected?


I am sure this topic is not new but I would like a new take on it...So the question is: Can one Over Dampen an older suspension chassis Thorens like a 125,145,160,166 etc.? I am only (in this post) regarding the exposed inner wood of the plinth like the base and inner walls. I have heard in some venues that it is easy to over dampen and KILL the dynamics of one of these older tables...Are they referring to more of the damping of the motor, platter, suspension parts etc. basically the metal parts or any damping? What are your thoughts?

Thanks!

Your experiences should be a salutary lesson to some, about the dangers of 'over-damping'.
Here is a quote from a learned dissertation on vibrations:-
Damping is always present to some degree in any real system. Without it, there would be no way to limit the amplitude of a resonance. The materials employed to provide damping, the ratio of these materials to those elements that need damping, and the method in which they are applied, all determine how effective any scheme is at reducing broad-band vibrations. However, you cannot mechanically "over-damp" a structure or component that is not designed to be a transducer. You can over-damp some circuits electrically; you can over-damp the "Q" of a speaker as well. You can also over-damp structures associated with a phono cartridge: a tonearm, plinth, etc. But you cannot over-damp a preamp's chassis or an equipment rack.

Note the 'over-damping'revelations concerning phono cartridge, tonearm and plinth.
Despite what some here have been propagating for years....over-damping of turntables, arms etc is not only possible, but can deleteriously affect the sound.
