@mahgister,I am sure that you know the basic ....Your post speak well for yourself...
No argument from me in regard to the influence of the listening room acoustics. But one has to assemble an audio system to place in the room.
But assembling a good system at low cost is relatively easy nowadays , thanks to great engineering progress in audio...
Embedding rightfully a good system, mechanically, electrically and acoustically, is less, way less easy than picking a good system to begin with....It was for me at least....
That is my only point.....And my post goes in the opposite direction of most audio thread where the solution is and always will be upgrading gear....
Then sometimes basic evidence are forgotten....
