Yes, maybe I can be more mind-calm with out removable headshell
additional connection joints but this is not the whole history as it’s
not what the you say about the bearing plane where it’s extremely
important for unipivots but with the solid Technics tonearms that is BS.
Its simple. The bearing *style* isn't the issue. Think about two people carrying a couch. On level ground, they both carry the same weight. Going up stairs, the one on the bottom carries more.
If the tone arm has the bearings in the plane of the LP, the weight on teh stylus remains pretty constant with bass and warp. But if the bearing is higher, the tracking force diminishes faster with bass and warp. This is easy to prove out with geometry and is why arms like the Triplanar, SME 5 and ET are set up that way. Some arms (like the old Fidelity Research) attempt to solve this by designing the counterweight to hang below the arm tube (which the Technics does not do, but would be an improvement for that arm) but this is not as effective as placing the bearings in the right place to begin with.
