Twl certainly knows what he's talking about when he speaks of matching mass to compliance, but the formula is not that simple. It is the total system mass - cartridge mass plus tonearm mass - which must be calculated in the formula, not just the tonearm mass alone. Given this, the mass matching may work in the Unify tonearm. For a quick way of figuring this out, go to http://www.vandenhul.com/artpap/phono_faq.htm#a2, which provides a convenient graph to simply add the mass of cartridge and tonearm and match it against compliance.
I personally own the lowest-compliance cartridge ever made - a Decca - and I can safely say that the Decca will always work better in a unipivot tonearm than in any other, mass matching issues aside. I'm actually a fan of unipivots, as it was a cheap unipivot which first beat my modded Rega which I championed for years. This type of tonearm, while fidgety, always sounds lucid and musical. The "wobbly" issue is never a roblem in practice, as the arm stabilizes within a very short time once the cartridge descends into the groove. If you like the Unify, for whatever reason, then take a chance, it looks like a very good deal. If in checking out mass loading you find a bad case of mismatching, then there are other reasonably-priced unipivots out there, including a Kuzma and an Audiomeca (which advertises on this site). Any other fans of unipivots out there?
