Me too. I'm considering some Xeo4 if I don't upgrade to the Raidho D2's. I would also like to know if there any sonic difference between the Xeo 3 & 4 other than being able to play hi rez.
And from a design standpoint, I'm not sure I love the new "pod" mounted up on top of the speaker. Were there any other cosmetic changes that I missed between the old and new Xeos?
