Good to see hopefully this thread is moving again.
Has discussion moved somewhere else?
Funny you bring this up, i was reading Stereophile Rotel and Bryston reviews and XTZ was used and a liitle review on one of the pages (either Rotel or Bryston).
Its not a matter of "prettier" graphical interface its a matter of easier to look at/follow + accuracy.
I believe that there has been a big improvement in the hardware, which the reviewer comments on. XTZ looks very good for room eq and straight forward operating for Rooms
Also there is a time alignment for aligning the speakers with the sub.
