@racedoc I am impressed the ViV 9" Arm superseded in use a combined value of Tonearms that must be near $12-15000 in total value. Must have been a great time doing the evaluations.
Myself on occasion receives a invite to play the role of an evaluator of a work going through R&D and as a working Prototype.
Usually there is a situation where a pre-version of the device under scrutiny can be introduced to the assessment and used as a exact mimic, albeit, as a earlier guise.
This is my interest in equipment and even though used in conjunction with listening to music, it is not anything to do with my interest in listening to music. The listening to music interest, starts with a passion for being present and sharing in a live performance, it can be a Busker through to a Stadium Concert. The listening to recorded music is secondary and a form of home entertainment, and the more the social activity achieved during any of the former are for myself for the betterment.
I really enjoy the creative work carried out by others, learning about the reasoning for the designs and how the designs are produced to reduce known flaws of other designs created and of certain Branded Designs.
I get to experience this through mechanical, micro engineering work, such as works done on Tonearms or Platter Bearings, or alternatively through electronics, such as Signal Path, Speed Control, or Power Supplies.
Fortunately, such days set aside aside for demonstrations are built on a social gathering and the fundamental aim is to spend time with like-minded company.
The work undertaken and being assessed is the secondary aim.
My experiences of sharing in the works undertaken by others, leaves me confident in my knowing these individuals are not lost, they are extremely open minded, a little insular with their IP, but quite interactive and willing to readily share the creation produced with over. Certainly not expectant to win favour with all, or in any way suggest another's choices are faulty and not worthy of a place. This is the antithesis of some of the most recent statements made within this thread by a few contributors.
I get the sense the ViV Arm has something of the above attached to it, maybe this is one of the reasons the Arm has an attraction to me.
In a recent post, it is made known I am soon to be involved with upcoming A/B Comparisons, where I am once more invited to be taking part in as an evaluator. This new period of assessments are designed to enable a much more broader usage of a range of Tonearm models are to be put under the knife, where a subjective assessment will be attributed to all models being demonstrated.
Your description does lead myself to believe there is a like-mindedness shared between us.
