I suppose that the easiest implementation to do repeatable VTA change would be the digital readout approach of the Kuzma. The other useful approach would involve changing VTA by remote control (Air Tangent). The VTA tower on the Triplanar and other on-the-fly implementations are still too much of a bother to me. Also, most VTA adjustment schemes do compromise arm rigidity/grounding of vibration to the turntable base. Those approaches designed to minimize the negative effect of a VTA calibration mechanism, such as the Basis/Vector approach, are not exactly convenient for making constant changes.
Still, changing VTA constantly would be a BIG hassle that would, for me, largely negate the pleasure of listening to records. For me, the biggest concern is with varying thickness of LPs affecting VTA. For that, the only somewhat easy to implement way to mitigate the problem is a long tonearm.
Vinyl listening inherently involves listening past a whole lot of performance compromises. Remarkably, it is still one of the most enjoyable of media. I just choose to ignore the comromise of non-optimum VTA for each record.
