Most rooms don’t need acoustical treatment.

You can make it more or less acceptable but if you want the best sound you got to treat the room, though I call it to tune the room. Sounds more correctly, less mechanical. Room as a musical instrument. 

Been saying this forever....😜

Millercarbon- What does “As soon as we move from the hypothetical home of the scoundrel to the particular home of the individual then acoustic treatment can suddenly matter a lot.”

On what planet do you exist? Why was it important to include the word “scoundrel”? Are you trying to come off as some kind of “Audio Sage”

I have recently purchased 2 GIK Bass Traps; the difference in sound is amazing.

As Erik said... Kenjit anyone? Utterly pointless post. 

It is not pointless. Many people have their systems in living rooms and cannot do their best in terms of making it the best acoustical place.
Erik doesn’t play analog and listens to Luxman integrated. Not very high standards. In fact...alright, I said enough.
