Tri-planar vs Graham


What are the sonic differences/characteristics of a Tri-planar versus a Graham arm?

I just acquired a Raven One turntable but already had a Tri-planar arm. I read a lot of posts by Raven One owners that have Graham arms so I’m curious.

The Graham is difficult to set up but Graham consistently has made the best sounding arms decade after decade.

The Graham is so open and quiet with dense harmonics that are a religious experience.

The Tri-planar sounds sparse in comparison.
Duane: I live with the Phantom since a few years and I change turntables very often. I have never experienced an easyer arm to set up, and cartridge alignment is a children play with his clever alignment devices. Once everything is set up correct, nothing changes, even when changing VTA on the fly. I am very admirative to hear how good this arm sounds . It is very important to play with damping fluid, starting from none to the "ideal spot" where sound is the best. Every aspect of arm set up has been widely studied by Bob Graham.
It is even possible to mount it on an SME armboard.
I've owned the Graham 1.5t and the Tri-planar and like them both. I have not owned or heard the Phantom. Of the two, I've owned I preferred the Wheaton.

Duane's wrong on two of his three points. I've owned three Graham's and they're not at all difficult to set up; if you've got half a brain. Tri-Planar's are also easy to set up and while sonically different than Graham, they're anything but "sparse."
