It would be most interesting to see some ceiling and floor treatment as well as corner treatment. I guess there is much room for improvement here because the listening room acoustics is the most important factor for the resulting sound quality. No wonder that there are minimum quality standards for studios‘ room acoustics.
There have been various kinds of treatments to the back wall and ceiling from bass traps, diffusers, and absorbers, for this, see the GiK, HOFA and RTFS reviews in which I also briefly covered the Stockholm diffusers, and the latest installment in HFA Setup History. I still have two RTFS SiRRAH diffusers/absorbers on the front wall. What I found is that the LP rack that you see in the left corner and the magazine rack on the right, together with the “walls” of CDs were more effective at reducing standing waves while retaining more liveliness in the room. If you refer to the previous setup, you can see that I also tried raising the racks all the way to the ceiling. I still have a massive stack comprised of RTFS Big Block and Small Blocks in the right rear corner. The entire story of this is still to be written when I find the time.
