Best Arm for Raven One?

I am using the Dynavector on my Raven Two, not the 507 but the 501. Cartridge is ZYX Fuji low output. The arm looks intimidating, but it is quite easy to use. To my ears, the arm lets the cartridge shows its character (in my case, lack of). :)

Slowhand, I am using an Ortofon AS-309S 12-inch arm on my Raven One, with a Dynavector cart. I've been extremely happy with this combo, and it was recommended to me by Jeff at Highwater Sound, as I could not afford the Phantom. The phono cable I use is the Synergistic Tricon Analog. If I had the money I probably would have sprung for the Phantom, but I feel I am not missing out on a whole lot with this set-up. Good luck with whatever you choose!--Mrmitch

Has anyone here tried using Origin Live, Rega or Moerch tonearm with the Raven one ?

I use a Dynavector 507 MKII on my Raven AC3 and it's a perfect compliment to the XV-1s cartridge. It was highly recommended by Jeff at HighWater Sound.

I am using Tri-planar VII UE II, have not heard other arms on Raven One, but came to this choice reading different posts... Overall, seems that Tri-Planar on par with Phantom 2, there are subtle differences in sonic reproduction, however majority (as I said in my first post) prefers Phantom over Tri-Planar.
