Listening to the M420 last night put a smile on my face while reading Mike Fremer's comparison of the $9K H&S Ice Blue to Ortofon A90 and Lyra Atlas. I felt no more than a slight tingle of penis envy for these MCs.
It's interesting how much smaller Acutex's tri-pole induced magnet assembly is in the 420 series as compared to the prior 320 series. The 320 marketing literature talks about the advantage of oversized magnets. Accordingly the 320 has a much larger and heavier 6.2gm 320 body. The cantilever armature of the 320 is also more complicated, with tabs that project radially to the induction poles inside the cartridge body. In contrast the 420 is a svelte 4gm. The 420 looks cheaply build in comparison to the 320. But maybe looks are deceiving. Unfortunately one of the armature tabs on my 320 is bent and in need of repair, so a comparison will have to wait.
