Suggestions for cartridge, just fancy a change of flavour

In my opinion you need an MM or MI cartridge for rock music if you want real slam and killer bass. Look for vintage MM from the same era (70s/80s). It’s been said they are closer to the mastertape. The very best MM are neutrail like the AT-ML170 for example. Hard to beat by any MC. Most of my vinyl are from the 70s too, i’ve tried multiply samples of the AT-ML170 and all of them are fine, but i ended up with AT-ML180 PCOCC. I have a perfectly working spare of my AT-ML170. You can also search on audiogon for users feedbacks about AT-ML170 or AT-ML180 cartridges posted before 2016. 

@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? 

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?
