John,
.
I have a Graham 2.2 (which I love), have heard the Phantom but not in my system) and have spent a weekend with the Tri-Planar (Wheaton) 7 in my system. I have a two armed set up so the comparisons were made by going back and forth between arms and using the same cartridges.
.
I don't think I can draw any clear conclusions on the Phantom since I have not heard it in my system. All of the posts from Graham 2.2 owners that have moved up to the Phantom are overwhelmingly positive in favor of the Phantom.
.
I love my 2.2, but the Tri-Planar was clearly superior to the sound I get from the Graham 2.2 I have spent time playing with the damping fluid (and got very positive results), but in the end the Tri-Planar was far superior.

Rgds,
