Very nice system. We share some of the same tastes, although you've gone far beyond what I have. I've got Maggie 3.7s, Spectron Musician III MKII with Bybees and caps (but only one!) and PS Audio DirectStream DAC. Even though your PWDII isn't broken in, you might really want to try out a DirectStream; for me, it was an improvement over the PWDII.
Beautiful room!
