Suggestions for cartridge, just fancy a change of flavour

Thank you everybody so far for the great suggestions

@rauliruegas you are comparing $1900-2100 MC cartridges to absolutely neutrial $750-800 MM with replacement stylus (boron, microline). The OP already has Shelter MC and looking for something else, guess why? Alternatives? 

I listen to lots of rock, ECM label stuff, acoustic and female vocal - Beth Orton, Joni Mitchell, Aimee Mann, Aretha, Imelda May - and went from a Clearaudio Virtuoso Wood to a Soundsmith Zephyr (original model) a few years back and really liked it. It was a step up in my system. After about 3 years I got the Zephyr MIMC Star (another improvement) and am running that now. I have the original at Soundsmith now being retipped. I have not had much experience with different carts - but am satisfied with the moving iron in my system and for my varied music taste. Soundsmith website shows their commitment to their craft. 

Dear @chakster : As I told you don't have any idea. The Shelter 9000 is something that you have to listen and different to the OP 501.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.

Raul, I don’t care about Shelter 9000 or similar overpriced MC cartridges, i have owned some of the best of them (brand new). I found vintage MM from the 70s/80s highly competitive for much lower cost (with amazing sound quality)! I don’t care if you prefer digital to analog. Or MC to MM, only several years ago your own statement was against the MC or at least "a great alternative to MC". Now your statement is totally opposite. You’re looking for perfection and audiophile’s life is a constant search for something. But i prefer to stay on something good, i use both mc and mm, and i know which MM cartridges are superb and not so expensive compared to 3-4k Lomc. For the price of one Shelter averyone can try 3 different MM with the best specs, materials (cantilever, stylus, coil wire etc). So what?
