I found that with detail to set up and positioning (using measurements and tape tape to mark changes) and by positioning with the tweeter section of my Maggies to the outside rather than inside, I was able to get very good and detailed imaging and a stable wide and deep stag - wether setting or standing, in or out of the favored listening position. If I change either or both speakers, even by 1/2", the imaging and stage, especially off axis, will somewhat diminish.
I agree with wolf_garcia, regarding your listening space being part of your home. I have no desire to turn my audio room into an anechoic chamber - it is a comfortable and integral part of my home, furniture and all. Since my floors are carpeted and ceilings soft fiber tile, about the only thing I needed to do was to cover the wall behind speakers with acoustic drapes and use one corner bass trap and it all looks, works and sounds great to me .....Jim
