Oh definitely. I read Kal's posts keenly. And yours and Brucemck2 too. I just wish he (Kal) would do some research on Auro 3d with the resources he has. I definitely felt a big plus on the Auro over MCH, the same that an MCH lover will feel over 2-ch. It adds that whole extra dimension without which the sound seems flatter. Similar to what will happen when you switch off MCH and just play on your two channels.
I suspect the the MCH music purist won't touch Auro with a ten feet pole, because it involves post processing of the native 5.1 mix. You could argue if you apply DRC you're not a purist anyway (fair point), but to me creating additional channels synthetically is a MCH bridge too far. Thenagain, if it would simply prove to sound better I'd be open to persuasion. But given the fact that I don't have the space (nor appetite) to cram more speakers into my room and re-architect my entire setup, it is a moot point for me. I suspect Kal is in the same 5.1 boat....
By the way, I recently played Adele live in Royal albert Hall and the vocals sounded like crap - something was amiss. I checked, and lo and behold the Dirac DRC was disengaged. Switching Driac back on and giving my amps 30 minutes to warm up and things fell back in place. I find this Adele blu ray a very good recording to see how well the MCH system is sounding and assess system changes, because with just one piece of the puzzle out of whack this soundtrack becomes unlistenable to me.
