Any good pointers for room treatments with maggies

Simon, I'll offer my observations as a 1.6qr. owner. I've added two kinds of treatment, both of which have improved sound quality. Without a doubt, the greatest inprovement came from installing four bass traps in the "plant shelf" areas on top of the two long opposing walls behind and in front of the speakers. This brought improvements equal to pretty major component upgrades. This treatment isn't Maggie specific, any setup would benefit in my room from the traps. The second tweak was installing DIY versions of Argents "Rooms Lens'" behind the speakers. These improved soundstage dimensionality and focus. You have to determine what your rooms' deficiencies are before proceding with sound treatment. If you head over to the Maggie User Group's website, you'll find all sorts of suggestions for different rooms and problems. It looks like many owners have rooms and setups that benefit from diffusion panels behind their speakers. Others resort to more decor friendly solutions like large plants behind their speakers for diffusion.
