Esoteric D-03 or D-05

I am interested in feedback from anyone who has witnessed these 2 dac units. I know the D-03 was first and more expensive but in theory the D-05 learned from the D-03 and has newer technology. Dynamics, proper instrumental weight and low end extension and clarity are important to me. I have a K-07x and a P-03 that it would be used with.

Thanks for looking!
