3K to 4K Phono Pre-Amp

Background: I am trying to upgrade to my ultimate analog set-up. I think the first step should be an new Phono pre-amp capable of supporting high-end MC eventually. I have read the controversy of step-up vs new phono preamp, but I am leaning to the new phono preamp. I have a Cary SLP-98P and love it.

Question: In the $3K to $4K range, what is the best match to a Cary AMP/Pre-AMP/Horn system that would provide good versatility as I later upgrade my cartridge and TT. I have read about the Aesthetic Rhea, AcousTech PhD, and several others but I simply don't have the experience or access to this equipment to help decide.

Cartridges that I may eventually purchase include Koetsu, Shelter, Transfiguration, or comparable. It depends on the tonearm I end up with.

Thank You
