A few weeks after buying my M3's driven by a Yamaha RX-657 I was watching Kung Fu Hustle and just could not help myself with the volume. There are a number of scenes in that movie that are just sonically delightful. It was only 9 or 9:30pm, but I received a knock on the door from the young lady who lived above me who very nicely stated, "Hi, those are some really impressive speakers. Seriously. But I have to work in the morning."
On her way back upstairs she did ask about the brand, and I did my best to give a blustery sales pitch while falling over myself apologizing.
All that said, one nice feature on the Yamaha (and I'm sure similar features can be found on denon/onkyo/etc) is the 'NightCinema', which basically just trims down volume levels on the lower Hz stuff. It's not as musically 'pure' as just turning the volume down, but it's really helpful when you want to hear the dialog but not the explosions (or organ pedals, or what have you).
