Of particular interest to me is the time domain rather than the frequency domain. It also seems people have sensitivities in one or the other.Other interesting things such as Low Q resonances being more audible that high Q ones.
One thing is for sure - The room and loudspeakers contribute the most distortion. As for the rest well,you can do your own blind testing but certain smart alecs may dismiss the results. Does it matter if they do?
Just like politics and religion,such is audio _ it gets people passionate.
