Mveloo,
Congratulations on your system! I agree with Vernneal above, that it warrants incusion in the ALL OUT ASSAULT category.
I was wondering if you had been able to A/B different room treatments, and curious which ones worked for you. Also, did you by chance try out the presence and absence of the flatscreen monitor at the main rear reflection point? This is a setup that I haven't been able to avoid either, because it's great for home theater, and very convenient.
I recently viewed (online) a room treatment/speaker placement seminar that included Charlie Hanson of Ayre Acoustics and Jim Smith of GBS among others. One of their most emphasized points was the great improvement gained by spending $4K to install a retractable projection screen. It got me to at least consider it. Any thoughts?
Again, congratulations on what must be an amazing audio experience.
