The acoustics principles are not only ignored but the way we can use them concretely are very complex to master in all their interaction...
For example how can we act on the acoustical material content of a room , with his peculiar geometry,topology, to create a balance ratio between the listener envelopment and the apparent width of the sound source ? How can we use the reverberation time to do this? Why are we in the obligation to investigate how do this instead of upgrading without end ?
A good gear piece design cannot replace acoustics controls, this is why.
I have my own answer to this appropriate for my room and ears. There is many other answers possible... Acoustics of small room is very complex matter, only ignorant can claim as above that everybody know this...Buying acoustics panels is not enough in most room case by the way ....
If those bashing the youtuber of my video and myself because we are faulty to suggest a reflection road about a complex problem, if those can understand even the way to pose the problem and know already the answer, they can answer for the benefit of all or go on insulting me and others giving sarcasms instead of thinking...
By the way laoman come in any thread i answer with insults even few times in my private mail since more than one year... His history contribution of attacks is easy to see if you go back in his posts history...
