I have been using the Graham Phantom series arms (currently Phantom II Supreme) with the Clearaudio Maximum Solution. Great combo. Adjusting VTA on the fly is awesome. I am adjusting VTA on almost every record I play, especially 200g vs 120g vinyl. The VTA adjustment makes a big difference.
The Triplanar is also great. You can't go wrong with either arms. My experience (in my system and friend's system) with the Phantom II Supreme is it is friendly with many different cartridges. It is not picky at all and works well with Clearaudio Goldfinger series, Dynavector xv-1s and xv-1t, Lyra Titan i and Atlas, etc.
