Edesilva-
I do not disagree with your philosophy. However, I only recommend using the number of speakers that correspond to the number of discrete channels in the source. Thus, for stereo, only two. For 3.0 (MLP and LS SACDs), 5.0 and 5.1, I find a center amp/speaker essential for coherent reproduction. I eschew DPL and other matrixing modes but DD/DTS sorta come along free with the full amp/speaker array. Or course, I am also talking about using a full-size center channel speaker identical to those used for the main L and R.
BTW, my experiments with the 3.0 SACDs were the most convincing of the necessity for a center channel but creating a phantom center with them was as unsatisfying as deriving the center signal from the stereo tracks. Several doubters have heard this advantage clearly in my main system.
