Best Arm for Raven One?

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.

Does anyone know the difference between the Dynavector 505 and the 507 mk2? Does the 505 have the arm like the 507 that raises and lowers the arm at the base for VTA?
