Yamaha
I would agree with the Yamaha assessment. In particular, the fully adjustable movie theater soundfield modes in the Yamaha AVRs(especially the upper echelon Aventage units)along with the addition of PLIIX in the rear channels when necessary, to me anyway, gives a considerably better, more spacious and realistic theatrical experience than Dolby, DTS or even the Audyssey programs on their own PLUS with the appropriate equipment you can have a 9.2 configuration all of the time.
