I made a comparison some time ago, I prefered overall the Triplanar, High Frequency Area has more information and detail, the Schroeder can create a different kind of soundstage. But it is more or less dependent on your system, on your cartridge and much more important on your phonostage.
What is also important to get the most out of it, is the Ability for the User to adjust the cartridge properly. And here are real differences, the Triplanar is very easy to set up, with the Schroeder it is a task.
I got now the new Phantom and that's THE one to go when you want to adjust a cartr. for 100% to get the most out of it. And both, the Tri and Graham work always in every condition, not matter, hot, sticky, rainy or whatever.
