Atmasphere, I am certainly a believer in considering how the sensitivity of our ears changes with volume as were scientists long ago. Harvey Fletcher and Wilden Munson wrote their famous paper back in 1933. Loudness correction was a standard feature in preamps back in the day. The problem was that only one correction curve could be used which would only be accurate at one volume level. My processor uses a set of 6 curves pertaining to specific volume levels. The processor automatically blends from one curve to the next as volume increases, Dynamic loudness correction. The end result is that the music sounds the same regardless of volume. Bass and treble are automatically cut as volume increases. Under these circumstances I think distortion/clipping is more obvious as it stands apart from the high frequencies of the music. It also makes listening at high volumes magically comfortable. Violins and female voices do not cut your throat. The processor also does room control. IMHO the importance of room control is not in obtaining a flat frequency response as flat sounds terrible at most volume levels it is in obtaining exactly equal frequency response in both channels. The end result being laser imagining as frequencies don't shift between speakers. Any speaker's frequency response will change with position as well as two speakers of the same model will have slightly different frequency response. This technology is starting to become available in various iterations and I expect it will drift down to lower price points. None of the currently available units have dynamic loudness correction.
