Hey slaw,
The main positives of the ViRa tonearm when compared to the Polestar (a high end Jelco) are a larger sound stage (both deep & wide) & improved clarity. The funny thing about the clarity is I never realized what I was missing until the new arm was properly set up. It is absolutely smooth, detailed, & dynamic. Like nothing I've ever heard before.
Negatives:
Setting this arm up is a b*tch, & it will unmercifully show every flaw (in spades) until everything is "perfect". Because it's a radiant tangent design, you cannot use the "normal" tools for set up. Why it didn't come with a template is beyond me.
Conclusion:
That stated, it is probably not an arm I'd recommend unless one has a lot of patience & experience in setting them up. Once set up properly though it has remained absolutely consistent and a beautiful performer
