Here is my observation. Majority of the dealers push Denon and marantz over yamaha. They also have only denon or marantz for demo.The main reason is the dealer margin is high for denon, Marantz over the yamaha so for profits all dealers push denon/marantz over yamaha. Coming to performance the sound signature of denon and marantz are the same. Operating denon and marantz you will feel the same as all the features and UI are the same and both use audyssey. The major difference with denon and marantz is the power amplifier. Marantz uses HDAM and claim its more audiophile quality. Also marantz has better built quality compared to denon. In performance they are same but lot of users claim that marantz sounds marginally better for music. I have heard marantz 5011,7011,6013,8012 and in denon owned 2400 and currently using 4500. I have only concentrated on movies and very well can assure you that you wont find any difference with Marantz and denon for movies. Both marantz and denon are soft, agile and gives a balanced, dynamic and neutral sound stage but yamaha feels more dynamic and muscular. So if you want subtle, crisp and refined sound stage Denon and marantz. If you want bold and muscular sound stage yamaha.
