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

Methods produced for Oil Damping on a Tonearm is nothing new to myself as something to be experienced.

It has been experienced as a Arc Trough and DIY Produced Oversized Trough with both a Vertical and Horizontal orientated Paddle produced to assess the impact a Paddle resistance can have.

It has been witnessed as a A/B comparison with a Identical Tonearm Cart’ with different Viscosities of Oil available for the Trough, in both Spirit Mineral Oil and Silicone Oil, as well as a Blend of these Oil Types.

This was done at a time when a alternative metal was under investigation for a Arm Tube, and not necessarily a homogenous metal.

I have no recollection of anything very attractive and indelible being perceived as having occurred, as a result of experiencing a trough in use. I do recall a few Oil Types were used.

I only had one follow up discussion on this methodology, which to me indicates not too much had a occurred to want to learn more about.

The follow up conversation made it known the trough was inspected under very high magnification and there was no evidence able to be detected on the oil surface, that a energy was being transferred though the paddle to the trough oil fill.

The discussions had that usually put an emphasis on where improvement was really to be found, was when the discussions centred around modifications undertaken within the bearing housing, for how they were an influence on what was easily recognised for being an impressive betterment than a earlier version.

The idea of a non homogenous Tonearm Metal produced from a Binderless 3D Printing to produce a Form with a particular spacing between between bonded particle is seemingly the real advancement to be discovered.

Technology today and the software that can control jet nozzles, places the Magnesium Powder as the material that has been most discussed with the Tonearm Designer, the metal that has much appeal for how it can control energy transfer as a non homogenous material, with Titanium Powder not too far behind.

I am visiting the designer builder of the Tonearm this weekend and will once more attempt to get them to take a proper look at Mycelium as a 3D Printed form for a Arm Tube.

This is as cutting edge technology as I believe I may venture into, in my later years involved with a interest in Audio and what the equipment can produce. 

Even though I say it is cutting edge Technology, 3D Printing as a concept able to produce a form is as old as CD.

Powdered Metal and other Particulate being used to produce a non homogenous form, with approx' 25% air space by Volume, is much older as a concept and working design, probably 100 years.

As a Layman description, I am not the man behind the Science.

These Forms used as a Binderless construction for a Wand will make transferral of energy that little more broken as the air spaces are now a place for dissipation of the transfer, resulting in diminished energy overall within the structure.    

The late Hans Henrik ( Moerch) once told me the DP6 I have would sound better if I could avoid the optional damping fluid.

Dear @audiomark1234  : Things are that for several years I owned the first the 4 and latter on the DP-6 that's almost an unipivot design ( has 2 bearing points. ) and with not good microscopic stability for the stylus tip ridding.

That's why came or comes with silicon oil damping for the horizontal plane and independent for the vertical movements and in this we can choose the " quantity " of damping we need or not but this fact depends more that what the designer says but  the cartridges we own and our sound reproduction preferences.

With out vertical damping we coulkd think is more open/cryztaline the sound but that could be the added non damped distortion levels.
