Will a more resolving CDP improve my system?

Hi. I have a fairly decent system that I have built up recently-Soliloquy 6.3 speakers, Conrad-Johnson PV10a preamp and MF-2200 amp, and an Arcam CD73T. I was looking to maybe purchase a nicer CDP (like a Consonance Reference 2.2) that was more resolving, with better detail. But, I am wondering-will a more improved CDP make much of a difference in my system? Or, is it too low-end to benefit much from an improved CDP? Everyone I hear raving about high-end CDP's seem to have high-end parts elsewhwere-my system's value at retail is about $7K. Should I spend another $500 on a CDP, or elsewhere (preamp is the next obvious upgrade, as is upgrading the amp with current parts). I live in a remote area and don't have the luxury of taking units home and demoing them. Thanks!
