Did you check the settings for DTS on the player? All of the Denon's I've seen recently have had DTS enabled from the factory, which is unusual because systems that have a receiver that cannot decode DTS will create a "pink noise" kind of sound that may damage speakers if turned up too loud when the track starts to play. Due to that, most players have DTS turned off from the factory.
Make sure DTS is also set to bitstream or normal not PCM.
