Johnny, before you get your shorts in an uproar remember that the Graham tonearm, considered by many the finest in the world, is a unipivot tonearm. Do you think there's issues here with MMs or MCs? The VPI tonearms are also unipivot, same thing applies. As is the new Basis tonearm, and the Nottinghams, and oh, yes, the Bluenotes, and...it's not a unipivot issue, which is simply a matter of preference, it's a mass-matching issue, and since most cartridges are designed for medium-mass tonearms, and most tonearms built today are medium mass, then sky's the limit, except for a few "difficult" designs.
