Hi David: I have used all of our cartridges on lots of unipivots - Grahams, Spiral Grooves, Naims, Audiocrafts, Moerchs and moreĀ
Haven't encountered any particular problems so far that defied careful setup, although I can imagine that some users may find it twitchy to set up tonearms that don't have stabilized azimuth.
Rather than unipivot vs. gimbal or knife-edge or whatever, consistent VTF is tied to the relationship between tonearm bearing height vs. stylus position (both should be at the same height). If the bearing height is low in relation to the stylus, the VTF will be reduced as the cartridge goes up (on warped LPs), and if the bearing height is high in relation to the stylus, VTF will increase as the cartridge goes up.
Tonearm center of gravity vs. stylus position will also have some effect on VTF consistency.
I don't own a VPI myself, but have heard from customers and dealers that some of the VPI tonearms seem to work better with our cartridges than other VPI tonearm models.
As always, someone who is good at setup will be able to extract a higher percentage of the sonic potential of whatever components are used.
kind regards, jonathan carr
