I watched that video and must have missed the part about Matt got about DL's correction not as expected so I might have re-watch it. Mind you, way back, he also said XT32 did not do well in its correction, something about making other mic positions worse, yet now he praised XT32 even though there has been no indication that XT32 (as it is still the same version afaik) has upgraded anything other than adding MultEQ X and Editor app that was by D+M, likely in collaboration with Audyssey.
So even if I re-watch that video I would take any subjective or semi subjective assessments on his take (with due respect) on Dirac Live with a grain of salt. It is hard to believe DL, and D+M would not have noticed something that is that concerning, they know full well of the high expectations from their customers who just spend additional hundreds of dollars adding DL. Yes, I am a skeptics on any sort of reviews of room correction systems, after trying different versions of Audyssey, Dirac Live and Anthem ARC Genesis, because in my experience, how the person use it will make a lot of differences if the user follows up using REW to see the results. Even the same person, using the same procedures, could/would yield different results for various reasons. To me, an objective reviewer such as Matt, should, hopefully had already investigated more, before concluding...
