Well... I have a Pioneer VSX-1014TX-k and when you run MCACC, it sets a 0 dB point which is at Dolby reference volume for any Dolby Digital movie. (It's similarly loud when playing back dts-encoded movies.) Depending on speaker and microphone placement, its maximum volume has gone from around +8 dB to +15. I have watched a few movies like this, but overall it's a bit loud for me. I like listening to the movies at -10 dB if I'm alone (about 1/3 of the movies I see here) and -5 dB if I am with someone else.
