Catridge for sme 30/2


I am planing on upgrading my turntable from rega rp8 to sme 30/2.
looking for recommendations for catridge to pair with turntable. Budget is between 2k-4K.
phono stage is ayre l-5xe.
I have been playing records for over 30 yrs but my technical knowledge in setting up table is bad. That’s why I have been using plug and play turntables . This would be my first venture into this level of analogue and am a willing learner .
Thank you in advance .

I recommend Ortofon cartridges, and we have an SME 20/3 with Ortofon Cadenza Black as our reference turntable setup. Ortofon cartridges have a little peak on the top that also helps to adjust azimuth, if the tonearm does not support rotation along its horizontal axis (roll). We use Dr. Feickert's Adjust+ to measure and calibrate cartridge phase / azimuth, and Dr. Feickert's protractor for alignment and overhang.
The Ortofon Windfeld Ti was used on the SME 12A in a room at the Florida Audio Expo and sounded excellent. 
Boy, that is a big jump! You're gonna love this. It has a V arm on it right?
That is a light arm which is OK, you can always add weight. I love ortofon cartridges particularly the Windfeld Ti. But, in this case I would prefer the Clearaudio Concerto. It is more compliant and very detailed. It tracks almost as well as the Windfeld but is a shade more dynamic. I think it is a better match for that arm.
