Sean, as always a most illuminating post. I listen to a wide variety of music and in a 33 by 14 room the typical listening levels are in the 70-80dB range. The music is loud enough to impede normal conversation. Even when cranking up the volume I rarely go above 90dB, but it's not because of any nastiness or distortion creeping into the sound at higher volumes. I suspect I am like many who simply don't have the need to listen any louder. It's a personal preference. For myself - via airplanes, motorcycles, small engines and trains - I have more than enough exposure to high decibel levels. Listening to music is refuge from that loud world and as a result I only like my music a little loud.
One point in closing. A tough test for any system is whether it can convey the impact and intent of music at very low volumes.
