@vair68robert Thanks for  your input. I am going to stick with the GIK panels for now because I am low on funds and also these panels made my room sound great with the KEF LS50s. Prior to the panels the sound was awful. I understand the CS3.7 is a different beast but I am getting close to the sound I want.

I am taking the the suggestion of unsound and moved my speaker back 1 foot from the back wall. This is the closet I have had any speaker in this room. Still trying to figure out if I like that positioning. Though with DRC it will not matter.

I am playing Santana's Caranvanserai SACD and it sounds pretty good. Thought last night when I played it on my headphones I was wowed and thought I need to hear this again on the CS3.7 in the morning. It is not as great on the speakers and I think it is not the room this time, Ii is the amp. This is an album where some power is required out of the amp. There is a lot of percussion on this album.

I got feedback from the DRC engineer this morning after I sent him my 2 preliminary measurement files. He plotted the measurement on a graph and the lines were very close from the 2 different days. The measurement with the desk in the room actually had a little better base. Though I liked the sound without the desk.  I will be sending more measurements today to get him going on the Convolution file generation for my room.

^ I would think that the very close (right up against the wall) would really only work with DSP. Without DSP I would think the opposite would be true, Though bass reinforcement  and less strain on the amp might be the case against the wall with or without DSP.

Keep the time domain in mind, especially for phase coherent speakers. On and off axis radiation patterns are different as the frequency rises. The speaker is balanced into an "average" environment with assumptions made as to where the front and side walls "might likely" be. Those assumptions never include placement near a wall. Perhaps you can unscramble the changes with DSP, but the differences with placement will be significant.

^I agree, when there is no DSP. But, that’s the beauty of DSP, it has the potential to remove those “assumptions” and replace them with real time and space measurements. Problems arise when the those measurements correct the relatively small in volume (not sound pressure) though more important primary direct sound as though they were the larger in volume (again not sound pressure) though less important reflected and distorted room sound, creating a weird primary direct sound. By placing the initial primary source of the sound close to the room boundaries they are more similar and there is less difference between the two. Flush mounting would be ideal. Due to the inherent bass reinforcement, it can also relieve the amplification of some burden, that might or might not be exacerbated by the DSP processing.

2nd- Santana 'Caravanserai' is an excellent SACD for testing one's system. There are 2 different releases on this title. I believe that I own the 1st pressing. MoFi is the re-issue.

Happy Listening!
