Looking for a Warmer Sounding Phono Cartridge

I've grown tired of the sound of high end MC cartridges. Detail aplenty, but I've begun to detest to the screechinesssssss.

No, my system is not biased that way. I'd consider my system neutral. Components are listed below. The Koetsu RS sounds wonderful. The other cartridges in my rotation are the Hana ML and the Shelter 901 MK III. These are not described in the literature as very etched sounding nor very detail rich. They are mostly characterized as neutral.
My ears no longer tolerate the highs, anything above 3KHz I would estimate. My hearing disappears at about 8KHz. I don't have any hearing problems except for the loss of higher frequencies. I find also that I'm not as interested in "getting everything that's on the vinyl". Not anymore. I want warmth with quality. I listen to the "audiophile" recordings, to R&R LPs from the 70s and classical and opera from all eras. Some LPs are very good, some not so, but performance overrides the defects. I want to continue to enjoy all of them.

So I'm searching for a good quality warm sounding cartridge, MM, MI, MC or some other, doesn't matter.

I've been researching the field and have come up with these candidates:

- GradoTimber Master 3
- Shelter 501 Mk III
- Soundsmith Zephyr MK III

I was pretty sold on the 501. based mostly on the article by Michael Fremer, but a very helpful contact at Upscale Audio turned me onto the other two. His advice sounds very sound and seems to come from experience with all three.

I would like to keep the discussion limited to the above three and to cartridges less than $1500 USD, unless there's a really great one that I've missed.

Thanks for your help.
