Sogood51...You have some nice equipment, so I understand why you couldn't afford sheet rock. At least you have priorities right.
Yes I have three Maggies in the front, and no, I did not properly set up the 2+2+2 configuration. It is difficult to do with the Maggies, and the switching needed to go back and forth between 5.1 and 2+2+2 is complex. I have small B&W and small Dynaudio speakers to play with, but I don't like the idea of introducing boxes into the system. I have listened to the height signals, and they sound like the main front signals recorded at a greater distance from the source. Perhaps there is delay also. What I may do is to put the "Height" channels at the top of a stairway leading to the living room. Nevertheless, I can believe that in a room with a high ceiling and with good speakers all around the 2+2+2 setup would be great.
If I were in charge of things the speaker configuration for music would be 3+2+1. LF, CTR, RF, RR, LR, Height/LFE. Only the Height/LFE channel would require switching between movies and music. Music people who need a subwoofer would have to derive their own signals by biamping the front channels (which is the best way to do it anyway).
Hope you enjuy the music. Good discs do exist out there but it isn't always easy to find them.
