I had a cartridge trial back in the 1970s which definitely had a mismatch with the tonearm as it couldn’t track any warp.
Prior to using a gimbaled arm, my Brooks Berdan highly modified SME IV from 1989, I used unipivots. I still use an Ultracraft 400 unipivot arm on a VPI 19-4 with a Grado G+ 78 cartridge with no dampening (silicone in the base). It works great.
For my LPs, I use the SME above with a Dynavector 20X2 L (previously with a Benz Ruby 3). It is so great other than setting up it’s VTA (spring loaded and coarse adjustments).
My best friend has an upgraded VPI Scout with a unipivot VPI arm. We don’t notice any problem with the bass using a Dynavector 20X2 H. Tight and deep bass, tracks warps great.
This is a very interesting forum. If I were to purchase a "unipivot" arm in the future, I will ensure that it has some type of balancing/range mechanism rather than a totally free floating (like my Ultracraft) arm. The Tri-Planar arm was a second choice to the SME but more expensive at the time.
