@daveyf Neodymium is king when it comes to flux per uinit density but i believe the strongest magnetic field ever created was via field coil.
as to whether different magnets sound different or by definition the strongest magnet type is best I'll answer yes and no. I have yet to hear a neodumium based cartridge that was as musical as an alnico or samarium cobalt magnet based one. The best cartridge I have heard to date is field coil based. I am currently in the process of trying the exact same cartridge structure with Alnico 5, Samarium Cobalt and Neo to see what happens.
