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 .

Thinking of Dynavector 17dx catridge , my local dealer says that’s a good match
This looks like ''back to front'' causality. From effect to the cause.
In some sense one can ask the right cart for the given tonearm but
the right cart for an TT is curious. As far as I know only our Lew
can have this this problem because of the number TT's he owns.
It seems obvious for him to ask the question ''which cart should
I use for this (x) one?'' 


Not sure why do you need such expensive cartridge if you think your tech knowledge "in setting up table is bad" ?

You can find excellent cartridges under $1500 and all you need to know is tonearm effective mass and cartridge dynamic compliance (at 10Hz) to theoretically match them together reading this article.

Maybe a cartridge with user replaceable stylus (MM or MI) is better for you ?
