Bravo barts, I agree. My system sounds best at 90-100db and does it easily at about 25 watts a channel. The key is very dynamic and bass heavy music. To each his own, but what I have come to expect from music is a connection that can only be had at higher volumes 80-100 dbs. As you said, the music and your ears will tell you what is enough.
What is the proper loudness for listening?
Paul McGowan via YouTube claims that each room, system and recording has a specific sound level at which music sounds most "real"
I've noticed this myself listening to my 3 different systems set up in differing rooms. Thought I was crazy to think so but I guess maybe I'm not?
Also, have notice in smaller listening rooms that lower maximum volume levels sound more real. Going too high on volume in a small room just overloads it and results in distortion
Any comments?
