@neonknight Thanks for mentioning the Dynavector DV505. That seems like it could be the perfect solution for my situation in that it’s a flush-mount and doesn’t require a massive hole to be drilled in my plinth. I’ve ordered one. It’s a bit of a fiddly arm, but the Rigid Float is just as fiddly if not moreso. From my limited use, there always seems to be a feeling of there being some slop, e.g. if I pull the cartridge out and put it back in, I feel like the azimuth shifts slightly.The VTA adjustment is kind of a pain, too.
I’m not sure how the unique Dynavector design will track 78s--hopefully a slightly heavier headshell will have enough effective mass to track my lower-compliance cantilevers with higher tracking forces properly without resonances. Overall it seems a lot more scientifically-grounded than the Rigid Float.
