I have seen 3 reviews for this reciever which appear to contradict each other. One review states that it handles proper DTS-ES descrete. Another makes no mention of this feature and only refers to DTS-ES. The last review I read states that it does not have DTS-ES as standard but is ES-COMPATIBLE! with an external decoder. All the reviews are in current issues of home cinema or hi-fi magazines. For the record, the Yamaha site also refers to it as 'ES-compatible'. What does the compatible mean? Who is right? How can one tell? Your thoughs and insights please!
