@mahgister , I am not arguing with what you have typed above.
I may well be the only one on this thread (and one of the only few on this site) who freely admits he is not knowlegeable.
And I also believe that if I had my system in a properly treated room it would sound better than it does now.
But I also know that in two untreated (probably acoustically unfriendly) rooms, I have made equipment changes and auditions that changed the SQ.
I also know that I have read posts from people who believe that they are knowlegeable that state (often unequivocally) that:
if you cannot measure it you cannot hear it
the room is EVERYTHING and next to the room the speaker is EVERYTHING
good speakers make crappy electronics shine and good electronics do nothing for crappy speakers
everything except for room and speakers is snake oil
anyone who believes anything other than all of the above is a victim of confirmation bias.
And I simply refer to those as being one or more school(s) of thought and I happen to subscribe to different schools of thought. Not that I wouldn't like better speakers and a better room. But I have heard very afforable speakers on electronics that were their match and electronics that were way above their level. I have experienced what an upgrade to those speakers sounded like. Then I experienced what upgrades and auditions of potential upgrades did for the new speakers. And all in untreated rooms. So I do not buy that the room is EVERYTHING.
