Esoteric D-07x vs PWD Mk2? Need info on SQ

Anyone heard these two in comparison? Also, if you've just heard one of them, can you provide details on their respective sound characteristics (and compared to other DACs)? Thanks much...Jeff
Hoping for some input. Thanks...
I've owned a D-07X now for a couple months and am liking it very much, unfortunately I'm coming from a W4S-DAC-2, so not much help with comparison to PWDmk2.
