Which MM Cartridge for under a grand

Hello 35off,
Pardon me for speaking of you in the third person, but I was trying to make a point. What I'm suggesting is not getting a 150MLX, rather using that stylus on your 440. They're interchangeable. The result might be greater than the sum of the parts. For the past 30 yrs or so, I listen to acoustic jazz almost exclusively, and the 440 with a 150 stylus is really good.

With a removable headshell it's relatively easy to swap cartridges if you have a shell for each cart. Once it's aligned and mounted, to swap carts all you need to do is rebalance. You might want a mono cart for those type records and maybe others with a different sound or presentation. You already have the 440, why not see what it can do and take it from there?
Regards,

It's not a moving magnet, but a moving iron is also a high output cartridge. In the new Stereophile Herb Reichert reviews the Soundsmith Carmen, which he likes a lot.

Greetings 35off, You have a great and somewhat rare turntable and arm combo that's in the top of the vintage direct drive class. I have had the same PLC590 table and PA 1000 carbon fiber arm in my system since 1980 and mine are still going strong. The only complaint I have is that the arms two set screws for the post make it nearly impossible to change VTA on the fly.
Both Flieb and Bdp24 above are giving advice that I would strongly agree with. If I were going to try an new MM type cart right now, I would give the Soundsmith Carmen very serious consideration. I heard its predecessor at an audio demo in Atlanta by Soundsmith a few years ago and was gob smacked at the level of clarity and detail. I have run a number of carts on my arm and table over the years, started with the Micro Acoustics 2002e, a Dynavector Ruby with step up amp, then the AT OC9, and recently the AT 150MLX mounted into a vintage Supex head shell. However, currently my best, most detailed sound is coming from an Ortofon OM10 cartridge body with a stylus and cantilever rebuilt with a line contact stylus by EXPERT STYLUS in the UK; that cart is mounted in a vintage Adcom "Skeleton" style head shell with Litz wire leads. My phono pre is a MS Phonomena II feeding into an Anthem D1 pre/pro, feeding a Cary Cinema 5 amp that's feeding a pair of Salk Sound V3 loudspeakers.
I also, have a JVC QL50 with Premier MMT arm in my upstairs system that is running an Ortofon 2m Bronze in a Jelco headshell that I really like. I have not yet tried it in my PLC590/PA 1000 setup, because I am so satisfied with the OM10 body with upgraded stylus retip.
