I understand that you have your methods and, as you go on to say, that you wish to influence others. Others have justifiably different methods and may go to extremes optimizing their systems because they hear the clear progress to music they cannot get by other means. I haven't claimed or denied any relative value of room work (and I treat first reflections too, although not mandatorily). I'm addressing general classes.I think you've made some valid, if somewhat circumlocutory, contributions to this thread, but are you questioning the value of room treatment? I am very happy to experiment with cables, but I would always prioritise optimising room acoustics and speaker positioning, and urge others to do the same.
GIK do a good range of domestically acceptable panels, and whilst this point was made in a rather patronising fashion in another post, I would agree that you are potentially holding back the performance of your system if you don't at least treat the first points of reflection
I have questioned the flawed logic (and the uncivil presumption) of those who declare better, system-oriented methods, including cable work, null and void out of hand simply because, as it turns out, they cannot or will not work at that level themselves. These are believers. These are not pragmatically skilled. Sometimes they're also insulting and want to control.
Refuting such impoliteness takes an exploration of the underlying philosophies, points, and beliefs, room obsessions included, and may be as circumlocutory as those fallacies and insults are broad. They have been broad.
