Upgrade - Front End OR Back ???

I have a dilemma. Currently I have an Esoteric X03SE, Luxman P1-u, and Audeze LCD2 headphone setup and want to upgrade. What will be the "bang for the buck" upgrading to an Esoteric D03/P03 or upgrade the headphone side (Woo WES with Stax SR-009)?
Thanks in advance

recently purchased Esoteric N-01 and wanted to upgrade the X-03SE but stay in the Esoteric line (no other manufacturers lines are in consideration), ANY suggestions?
thanks much
