Amethyst versus Nagaoka MP-150/MP-200


Does anyone have any experience with these two carts, by any chance?  I have the Amethyst and I've used it for about 40 to 50 hours now. I think it's a beautiful cartridge, and I'm a fan of Sumiko in general, but it doesn't hit the spot like some of the other carts I've used.  So I think I'm going to sell it and buy something else.  I've had my eye on the MP-150 for a while.  Would be curious to hear folks' thoughts on this cart, especially from anyone who has heard the Amethyst, too.  (Also, if anyone has thoughts on what a good selling price for the Amethyst would be, please let me know.)  Cheers.

Sorry, didn’t see this earlier.

The Amethyst is a bit brighter than the Olympia to my ears, but it definitely has that Sumiko warmth and musicality. I really love it, esp for jazz. I also find Ortofon carts too hard, dry, and bright. I like them in small doses, but with Sumiko carts and my MP-110 I want to keep listening to the music, whereas with Ortofons it always feels a bit like a science experiment after like 15 minutes.

Still trying to decide if my next cart should be a Moonstone or MP-150, though. My fear is that the MP-150, precisely because it’s brighter and more detailed, etc., will lose that warmth and softness that the MP-110 has.
Nagaoka MP-200.
Boron cantilever has nice warmth and more detail than MP-110. Also killer bass response.
If all else fails, just get a Lyra Delos. Will end all your problems. Lol
Not sure I'd like the 200 as much, but part of the appeal of the MP-150 is that I could upgrade the stylus down the road.
