I've just finished reading through this thread and decided to make an Audiogon account to thank @mitch2 and @fuzzbutt17 for the really invaluable posts and to be notified when there are new posts here.
Also, since @fuzzbutt17 is looking for opinions on new face plates, I figured I'd throw in my thoughts. The thing I don't like about the look of the current Mojo DACs is the large "Mystique" in papyrus font on the face plate, so this seems like a great opportunity to move to a cleaner design. I quite like the more minimalist design of Merason and Schiit DACs, so I would vote for "Mystique" to either be smaller and in a cleaner font on the front, or just not have anything at all on the face plate and have Mystique only on the back. Silver and black anodized on its own looks very nice.
My current DAC is the Merason Frerot with the Pow1 LPS. When I upgrade, it'll either be to a Merason Reuss or Mojo Mystique Y (barring any new Mojo models). This is for a desktop headphone setup so I care a bit more about aesthetics since it's on my desk staring back at me haha. If Mojo were to create a stripped down version of the Mystique Z Q with just a USB input like the Y, and with a new chassis, it would make my upgrade choice a no brainer.
