So if you agree that it is subjective, the original poster should go and listen for himself, instead of taking your words for it and assume that NAD sounds better to him. I am sure to many others, including me, Yamah and Denon sound just as good as the NAD. To some, Yamaha/Denon may even sound better. If he was to choose reliability and features, then based on your previous posts, Yamaha is the way to go.
As for the external amp thing, I just thought the poster may be interested in comparing the cost of a Yamaha (has a clean prepro section according Audioholics) plus a 2 channel amp and that of a NAD receiver that has a robust amp section.
