I own both an Origin Live Silver 3a and a Conqueror 3c. IMHO the goodness starts at the dual pivot arms, so Encounter and above.
I also had an Audiomods Classic, which is different than their TOTL arm. Sold it on.
Have never owned a Roksan Nima, but have set one up and it is a sleeper. Lower effective mass though. Very good tonearm. Best of luck.
