I'm not sure I've seen the Phantom on a SOTA - are you sure it fits with clearance on all sides? The magnetic outrigging might make for a tight fit.
I got my SOTA Star years ago with a Fidelity Research FR64fx (vintage Japanese arm), and to me that's a perfect aesthetic and sonic fit for SOTA. It's a little on the heavy side (2.2 lbs) but it works. I also preferred 64fx over the Phantom on my other tables.
