Amethyst versus Nagaoka MP-150/MP-200

I listen to a mix, and I definitely don't obsess over finding mono pressings, etc.  In fact, I'm just as happy with more recent reissues so long as they have the musicality/warmth of the originals.  (And of course not all originals have that anyway.)

I think of Sumiko as warm, so it's interesting for me to hear you say that Nagaokas are warmer.  My entire system, from phono preamp to speakers, tends to run toward warm, so I actually wonder if adding more midrange/low end from the cart will throw off that balance and muddy the waters.  Or maybe there will be even better synergy.  Food for thought. 

Thanks again for your thoughts!  

@three-paws There are definitely times when I hear warmth, especially when playing jazz trios, jazz ensemble, beat mix tracks, DJ or electronic lounge beats. This is again the intention of those tracks, hence I used the term: “pure.” On the contrary, I wouldn’t put a Stravinsky symphony or Dua Lipa in the same “warm” category simply because of the varying genre. I value hearing sound as it was recorded - “as if you’re there” - which many of us appreciate. 
In visualizing your system I think you built a robust system deserving of different cartridges. But if you really want to sell there are outlets that will buy quickly. Good luck and happy listening! 

If that's how you're defining pure, I'm a bit confused, as I don't think the Amethyst replicates the original tonality with some magical accuracy.  I think it gives them a warmth that isn't inherently there.  That's actually why I like it so much.

Btw, I'm not sure what in my post has given folks the impression that this is my first cart, etc. I have several TTs, amps, speaker pairs, etc. I am just asking about these two specific cartridges, not for advice on how to shop, how to build a system, etc.

@three_paws 

noromance , do you find the AT bright/fatiguing at all?

Nope. I have the 750 on a 401. However, give it about 20 hours. It's not in the same league as my Deccas but it is fine with good frequency response and detail. 

Just a note here. A detailed cartridge is not bright or fatiguing. That is a system issue. Shying away from them is covering up another problem.
