@dogberry I have made it known within this thread previously that a similar trial as your own is intended to be experienced on a New Tonearm Design I am very familiar with.
I am not sure when this is to occur, but it will, the designer / builder of the Tonearm is inquisitive enough to want to know how the experience will impact on them, I am keen to see how the experience impacts on me as well.
A mod' to a Headshell is easily achievable, nothing ventured, nothing gained.
Your thoughts on what you experienced even with the proposed notion the Geometry might not be ideal, should not be a reason to deter, is the not the whole debate about overhung / underhung all about the Geometry being incorrect on one type and the compensation measures in place on the other type being negative influence ???
