There is some objective collective truth in sound perception, but musical perception is more complex than just sound perception and taking into account the different genetic potential of each one of us and our own different individual listening history, it is impossible and illusory to reduce this individual history to some objective collective laws of hearing...We lear to listen music on our own term with a specific history and potential where we transform our own experience with musical experiences that are very different and varied in their impact for each one of us...Our continuously transforming experience with sound is the way to go deeper in our personal musical experience...Music perception does not reduce to sound perception at all...
When i buy a piece of gear, or evaluate my room, or judge the impact of some modification in my audio system, i dont claim for a universal validity, but i claim and vouch from my own experience and personal history of listening, in my particular room with my particular gear... Reducing that to an A/B/X test is pointless... But testing ourself in some confortable personal environment and with our gear with an A/B test is, like says wisely Paul McGowan of PS audio, a necessary and instructive experiment to improve also ourself ... It is the listener own environment, mastering his own decisions, that are keys to personal improvement in audio and musical experience...
What i speak about is from the subjective point of view of a listener in a process of experiencing music more deeply, and modifying his own perception of sound, with new gear or tweaks etc ,with this goal in mind and with his "own musical perception particular organ" create by his own history...
Reducing that complex and very individual and personal history with ABX tests to some engineering laws of sound emission and perception is only truncating the musical experience to the lowest denominator, it is perhaps good for marketting, or engineering technology, but not a method able to explain musical perception in his relation to sound perception in an individual personal history...
