Top 3 high compliant mm/mi cartridges

The Grace F9E or F9E Ruby, with (assuming it has been used significantly) Soundsmith's $250 ruby cantilevered/elliptical stylus "retip."

The cartridge is rare, sought after, and expensive for a vintage cartridge, though (with good reason, IMO). A non-ruby F9E that was offered by a seller in Japan, apparently in excellent used condition, recently sold on eBay for $437.

A correction to my previous post: I misspoke when I used the word "elliptical" in conjunction with Soundsmith's $250 retip option. From their website:

With exacting care to angular positioning, we install a RUBY "Single Crystal" cantilever which holds a Nude "Contact Line" diamond, one of the most sophisticated stylus/cantilever assemblies ever made and often superior to those found in cartridges costing many thousands of dollars. This combination creates an ultra low mass system, capable of the finest reproduction from your cherished vinyl. The Contact Line Diamond has three times the contact area in the vertical direction of the groove wall compared to an elliptical shaped diamond. This lowers the "force per unit area" on both the diamond as well as the record groove, resulting in lower record and diamond wear. This upgrade can be done to almost any cartridge and stylus assembly. Once done, tracking force can usually be reduced to 1.3 - 1.7 grams.
