tobes... that arm tube looks very much like the Grace 707 design I used to own.... which sucked with Grado.
Off topic of the OP, but I also owned the 707 long ago and fail to see the resemblance. Totally different headshell, very different armtubes and the Grace was a gimbal design?? Not to mention that the Grahams armtube uses concentric tubes with constrained layer and ceramic outer tube. The Grace had an effective mass of 7g vs 11-12g for the Graham.
I never used a Grado with my Graham 1.5T when I owned it, but i'm sure it was far better damped and had much superior resonance control to the 707 (the bearings of which weren't that great IMO).
