On 1.2.6 vs 1.2.7, I just finished up a mini-shootout using a slightly different set-up (Lyr armed with Siemens tubes paired with HD800, no EQ at all). Bottom line: 1.2.6 wins and wins big. Orchestral music sounded tinny and annoying on 1.2.7, unlistenable. Much more thump (slam?) and lower end is much more defined on 1.2.6. I accused it of having less soul than 1.2.2, but it fits in nicely with Lyr/HD800. Still bright and detailed (and somewhat harsh...I probably need to swap tubes from the Siemens to the Amperexes, but that would've screwed up the comparison plus I'm lazy), but far more natural than 1.2.7. Might or might not get to the other two firmwares.
Whatever Ibasso did to 1.2.7 sound, I hope they undo it. Sounded muddy on the other rig, harsh on this one.
