1) Well beyond the lack of roll-off at the low end and the dip I suppose the high end roll-off could have been lifted from or inspired by SMPTE.
2) I don't listen in the far-field. I suspect few people do at home.
3) I suppose. But most rooms and most speakers need EQ of various sorts.
4) I don't think there's any consensus on that point. All live music is idiosyncratically modulated by the performance space often with deliberate intent. Cinema at least offers standards even if they're not used.
5) I don't think there's any consensus on that point. But certainly the most common complaint I read about Audyssey is thin bass (followed by harsh treble).
6) Have you compared other ARC/DRC systems to Audyssey Pro?
1) Yes, plus independent research done by Audyssey and others.
2) Au contraire. Most home listening is done in the far field. Unless your speakers are about 1 meter away, it is farfield listening where room reflections start to become significant. That is the meaning of "far field."
4) But with music, you have a live sound reference in live concerts. With movies, I really do not know exactly what Meryl Streep's voice sounds like. I have never met her in real life, much as I would like to. Car crashes, explosions, helicopters, etc. are not good references, because they were recorded under acoustic conditions unknown to us. Yes, they sound "real", but we do not know which version of "real" is actualy on the soundtrack.
5) No, I think there is broad professional consensus that bass should be measurably flat in your room (at reference level). It sounds more like live music to me that way, as well.
6) I have several friends with Anthem D2V's with ARC. It provides very similar results. We once did a listening session of a D2V (ARC calibrated) vs. an Integra DTC 9.8 (Pro calibrated MultEQ XT) side by side in the same room. There were no obvious differences in the sound; they were virtually indistinguishable with Mch SACD - hats off to Integra for matching the sound of a > 4X more expensive unit! But, personally, as an EQ system, I believe XT/32 with Pro is superior to ARC due to the higher filter resolution of XT/32 and other factors, but I have not done an A-B comparison. ARC is, however, much faster in doing the calibration than Pro.
