Absolutely ! I had a much more uniform bass response and treble dispersion with MDF instead of glass. When i knocked down the half brick wall and went from 6 m to 12 meter room dimensions, the extra length gave bass development in the room a big step forward, especially standing waves at 50-60 HZ disappeared, giving new details in the bass range. My system does go low in the bass range and the extra space was a big improvement. The larger room also looks better, and after having replicated the half wall in my "rack" ( i was using the top of the half wall for equipment) i still have the very solid foundation for my equipment, i can drop a anvil right next to my TT without skipping a beat !
It is refreshing to see an audiophile prioritizing the room. The best gear does not nearly sound as good as it could and should if the room is not right.
A big thumbs up, Milan!

While I have to live with the room that I have, I still try to improve it as much as possible, even though I am slower with that endeavor than I could be (and I have nobody to blame but myself).
