Very interesting - I am guessing you must know exactly what you are doing, given your comments about tweaking and the obvious room treatments and things. In general, your room and system look very nice and very meticulous.
I immediately notice, however, that your speakers do not appear to be placed on axis.
Is this because you listen from the chair on the right hand side of the room? Does that yield better results or is there some other reason you have the speakers set up to fire ever so slightly across the room?
I would love to hear your thoughts and experience on this.
Perhaps it is a distortion of the photograph, but I can immediately spot speaker placement that is off by even a few inches. In my Magneplanar based systems, this has always made a huge difference in both the imaging and the tonal response.
