New to the site and hoping there is still some interest in this thread.
I have spent several years working on composite pole pieces (mixing magnets in single pole pieces) and am not a big fan of NdFeB magnets. Their major contribution to tone comes from eddy current losses in the coatings (nickel with copper undercoat) that are applied to their surfaces to prevent oxidation. This 'dulls out' the tone of an alnico pole piece without adding additional harmonics.
I made a couple of short recordings of a pickup with and without 1/32 thick NdFeB bottom pole caps and can send them to you if you want to contact me by email.
