"I’m curious about this.
I think my system sounds pretty good but am wondering with room treatment would it sound better. Without spending a bunch of money how does one evaluate this?"
I was a room treatment denier. There I said it. I was also a cable denier. However I have now recognized that being a denier is not the way to hi fi happiness.
After some encouragement from friends in the hobby I added some sound treatments in my room, and they made a significant improvement. Total cost was about $800 from GIK. My system is posted so you can see the ceiling mounted panels. The panels on the sides are still to be mounted on the walls.
