Sorry for the late reply! Been away on vacation.

The difference that the GIK room treatment made was huge. The room before hand was un-listenable. The room sounds fantastic now. I wouldn't mind adding some 3D diffusors at a later date.

As for the 244 panels I used these on the side walls as first reflection panels. The tri traps were stacked and positioned in the rear corners of the room behind the rear speakers.

I really recommend investing in room treatments before $$$ in the source components.
