Spiral Groove embraces the same design philosophy as Ralph is espousing. "the bearing interface situated in the same horizontal plane as the stylus resting in the record groove"
https://sme.co.uk/audio/product/series-v/
Likewise with SME’s Type V (which does not use unipivots). "Carried in massive yoke on 10mm ball races. Axis at record mean level to minimise warp-wow."
And although cartridge manufacturers would love for universal-headshell tonearms to become more popular (because that would encourage customers to own more cartridges), many high-quality tonearms, including those mentioned above, do not use removable headshells.
While it is clear that the universal headshell is very convenient for changing cartridges, in terms of mechanical rigidity and the quality of the electrical contacts, it leaves something to be desired.
There are valid reasons supporting either option; there is no need for a specific agenda to be present for someone to have a preference either for or against universal headshell tonearms.
