Help with Cartridge selection

Definitly a lot of information and great recommendation. I thank you all! I will be referring to this thread in the future when I upgrade.
I have decided on the Dynavector DL20X-L, at $750 it is a good starting point. I know with my other gear it has been a work in progress for years, I know the same will be true with my cartridge selection. I'm always tempted to go for the best I can afford but I need to establish an ear for my system with the added TT. I need to hear the improvements that are sure to come as I get a feel for the analog sound back in my home.
Dougdeacon- After reading your review (I did find it..duh)
of the ZYX Atmos I was very tempted to forget my budjet limits...lucky for me I could not figure out how to get a price for one or even if they are still available. I did find plenty of the 4D's for way more than I can spend at this point!
I think my TT is about 2 weeks out...plenty of time to get a cartridge.

Correction: Dynavector DV20X-L

Anyone want to chime in on the Benz Micro Ruby (wood body) low output 0.3mv cart.
New Dynavector dv20x or slightly used Benz Micro Ruby?

I have a Dyna XVS, a Benz Ebony LP, and a Benz Ebony H. I listen to all kinds of music and for me, the Benz sound has a bit more more of reality of what I think is live music, than the Dyna. I must add that the H is in some ways even better than the LP, but the LP is the best for these ears.

Buy a new Dynavector DV20X-L or a 40hr used (40hr) original Benz Micro Rudy wood body?
TT will be a Basis 2200 signature W/Vector4 arm.
Thanks,
Greg
