My room is fairly small (14' x 12' into the alcoves) so placing the speakers is pretty difficult. In particular the only place to put the rear is in line with the sofa with one of the rears 3' closer than the other. I figure that an amp that can set independent vols and delay times for each rear channel should sort this out. I was thinking of the Marantz 4200 because its rated for both stereo playback and home cinema but it appears that it doesn't have this feature. Can anyone recommend an alternative av receiver that can be configured in this way?
