For those seeking a more "stable" platform for their cartridge that combines all the virtues of 3D construction (non-resonant, tonal purity) and unipivot design (extended treble, lots of inner detail) you may be interested in the new VPI 10" gimbaled arm that is a (superior) variant of the one that will appear on the Levinson table. I had a unipivot 3D-10 for about a year and it performed extremely well on my vintage Scout. I was able to work with Mat and Harry to outfit a "curvey" Scout plinth with their new gimbaled 3D-10 and can tell you that it has all the virtues of the unipivot but improves upon the bass response (deeper and tighter), imaging (tighter focus) and resolution (more inner detail and less distortion). The sound has that elusive combination of a relaxed presentation with extraordinary detail that I have heard in a few select top tier vinyl playback systems. I posted pictures on the VPI forum for those interested in taking a look....
