@12many By the way, I like your handle – clever!
Agree that what is heard gets incorporated.
I agree with others that music is an ASC. (I mean, what isn't an ASC given certain definitions? That's a rhetorical question, FWIW.)
The point of my question (which is not as fun as what others are bringing up, so it's all good) is how do we break out of "ruts" in the way we are presently analyzing our systems? So many people on the forum seem stuck about what to do next, and they look for advice about gear, etc. But one could change a thousand things, and so the problem comes back to how we break out of our larger perspective. An ASC had long ago is of little help, as it has already become routine in our present habit. A new ASC has the potential to shake up present habits, provide an analytical clue, and lead to experimentation with the system or room with greater potential.
