^ 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!

Some important news was found out from my DRC measurement steps (first step actually).

I want to clarify a point about the slight harshness I was hearing on the CS3.7 top end. I was saying it was not as smooth as the KEF LS50.

The measurements showed that right speakers Coax driver is out of phase with the left speaker Coax (maybe one can say the opposite). There is some harshness on the frequency response due to this miss-wiring. I guess my hearing is good.

Prior to the sale I knew that the previous owner got a new Coax driver from Rob G and soldered the Coax wiring himself. He was a little worried about the wiring since there was a 2 week delay with shipping the driver to Rob and getting the new one. Anyways, the previous owner and I are working to get this fixed, should be an easy job. I will give Rob a call tomorrow to find out the specifics of the job.

So the DRC work is halted until this out of phase issue is resolved. I am going to find some electronics guy/gal to do the solder, since I am a newbie on that and I want it perfect.

BTW - the engineer up in Canada, Mitch Barnett, used to owned Thiel CS3.7 and he loved them.

@jafant My pressing of the SACD is from SME records. I now have my SACD player less than a foot from my seating position. Makes things easy. Getting real lazy with age.
