A consequence of this acoustics perspective and necessary training, is that all reviews are heavily conditioned by the acoustics conditions of the listening system/listener/room, then reviews are not an information which can indicate way more than personal taste.
Real synergy must be tested with many pieces of gear and measured techs.
For music recent scientific article demonstrated that we perceived "timbre" the same way among all cultures, and "timbre" is the root of musical various musical scales in use all around the world..
The consequences for audio are evident : the perception of timbre is one of the main aspect for music and cannot be measured by few techs numbers but must be listened to by ears/brain. ( one of the reason is in psycho-acoustics linked to the way the ears lives and brain create sound perception in his own non linear time domain).
If all reviews are subjectivist taste, and if all technical gear measures are objectivist limiting insufficient few numbers; the only way to assign a meaningful value to a system/room is to study the acoustics basics and the varying acoustics parameters to makes each one of us in control of our own experience. Then free from our ignorance and easy prey for maketing.
