Filling Room s with Sound

So are you saying the room with the 2 higher end speakers for mains has a different sound than the room where all speakers are the same, with electronics being the same? You're interested in discussing these differences in 'effect' between the two 'schools of thought'?

one room has a center and three pairs of identical floorstanding speakers - works great for HT, the floor standing is easy to position without furniture.

For all channel stereo it's even better - the speakers in common fill the room evenly

My other room still uses floorstanding speakers with more expensive and powerful fronts in all channel stereo it's a different effect than the other room.

both rooms are driven by gear in an a/v closet with components duplicated for each room - two a/v receivers, multipple amps. splitting hdmi source and other source to feed both receivers so both rooms can have the same source or not.

i don't see the whole house stereo folks doing this

huh?? Maybe try again and restate your position. Thanks.
