Versatile is perhaps a more appropriate term than universal. The tonearm closest to being universal is probably Audiocraft AC-3300/4400, which offers 4 different counterweights and 2 different sub counterweights but also various armpipes, including those specifically for SPU A and EMT TSD. And it offers adjustible oil damping. So far I have been unable to find a cartridge that doesn't perform well in this tonearm. That being said, there are some low compliance MC's that simply adore the FR-64/66 arm, like FR7, Ikeda 9, SPU and Miyabi. I assume the same goes for the later Ikeda arms.
