I have both Raven 10.5 and Graham Phantom II (upgraded from I, might further upgrade to Supreme) mounted on Raven Two TT. Still not get to the point to offer any valid comparison on the sound between the 2 arms. But I will offer some of my observations and I think it's helpful.
Installed Raven 10.5 about 4 months ago. Upon fine adjustment of the arm, noticed an issue with Anti-skating, and the arm also skip quite often when lowering onto the LP. I thought my table might lose level, but it's not.
Just mounted Graham Phantom II in the past few days.
When put two arms side by side, I found Phantom is easy to setup especially on the pivot to spindle distance. Phantom also has measurable/repeatable settings for VTA, Azimuth and Anti-Skate. In comparison, VTA on Raven 10.5 is fine, but Azimuth is tough, anti-skate is kind of joke at least as of now.
Phantom offers a plastic spindle cap. There is a hole on the head shell that will fit in the tip of the cap, which will help greatly to setup the distance between pivot and spindle.
The paper scale provided by Raven 10.5 is very hard to use to setup the required 251.2mm distance. I set it up before inserted the Raven arm in the armboard. While mounting the phantom, I happened to notice there is also a hole on the Raven 10.5 head shell, in very similar position as the phantom's. After removing cartridge from Raven 10.5, I tried to measure the distance again from the tip of the Phantom cap to the Raven Bird, I found my original distance is short by 2mm or so. After adjust the distance of Raven 10.5 to let the Raven 10.5 head shell hole sit on the Phantom spindle cap (not quite fit in), I found the distance is quite close to required 251.2mm. Very interesting, I am quite happy that upon installing Phantom, I also solved a problem to setup Raven 10.5 without investing more tools offered by Uni-something or Feickert.
