Helius tonearm users, what have you upgraded to?

I have not heard a Helius tonearm (although I hear that they are great with my turntable, a Townshend Rock), but I just upgraded my tonearm from a Moerch DP-6 to their DP-8. And wow. What a great improvement. That DP-8 is a killer arm. Well worth trying to listen to. And if you are in the US, Mehran at Sorasound is fabulous to deal with.

I am using both an omega and an aurora. Both are excellent, as good or better than my sme345 and IV. I would buy the omega ruby if one becomes available at a good price

Hi Manitunc,
I have a Kuzma 4 point arm and I am thinking of getting an Omega (Ruby) as a second arm, but I know Helius is rare in the market. So i wonder how it performs.

Is the armbase mount a Helius own proprietary geometry?
Thanks
