This is the Shelter 501 mkII, NOT the mkIII. Output is 0.1 millivolt less than than the mk III - which is the only difference.
Rating: Rated a conservative 8 mainly due to storage on shelf due to non-usage. It is in excellent condition, in a non-smoking environment, and only used as a backup cart between upgrading from a Dynavector Karat 17d3 to a Dynavector XX-2 mk II.
Ownership: Original owner. Comes with special mounting screws and nuts needed for mounting, original box, and paperwork.
History: No service history. Tracks and performs absolutely flawlessly for a .3 x .7 nude elliptical. Cart was mounted on a VPI Scout 1.1 with VTF @ 1.8mN, and aligned using the proprietary geometry determined by the black VPI alignment jig.
Miscellaneous: I was very tempted to contact Soundsmith to upgrade the cantilever to boron and get a microline stylus and keep this cart, but decided against it as I upgraded to a Dynavector XX-2 mk II instead.
