Cartridge recommendation for classical listening


I have a wonderful sounding Grado Reference Sonata cartridge which I love.  The only problem is, for many years, I have had a hum problem which I have investigated extensively but never found a solution for.  I know Grados can have this defect, and the extensively modified Rega P3 turntable I use can contribute to the problem
So,  I’m ready to give up and go with another brand of cartridge.
I listen almost exclusively to Classical music.  Can anyone suggest a cartridge under $1000 that sounds good for classical?

Hana sounds good but it ’s dynamics are too low for symphonic music.
The Rega Exact 2 I use is a solid body and is made totally in England  by Rega and Rega alone .Very high  quality.
I recently put an Ortofon Quintet Red on a Linn Akito and after some break-in it sounds astonishingly good, and not music genre specific one iota as befits any good cartridge (or any gear for that matter). I'm looking forward to exploring the rest of the Quintet line if I get tired of the Red...but for now it's so good it's likely gonna be around until I wear it out.

My quest is over!
Thanks everyone for your valuable input.
In the end I had to let practicality dictate the answer.
I decided on the Sumiko Blackbird.
The store expertly installed the cartridge free of charge.
Out of the box, I am happy to say that the Sumiko has made me more than contented
It’s in a different league from the Grado
 An excellent match to my CJ,  I hear details and subtleties I never heard before. No harshness.  Very refined presentation. More real.
And, no trace of a hum!
Once again, I hear the niceties of analog sound.

Again, to all, my gratitude for your input.
