If your player is dvd-a capable it will have a dvd audio logo on the front.Most dvd-a disc have dts/dolby 5.1 also,but this is digital.The dvd a player has 6 analog outputs that go to ext.inputs(6)2 front,2 surround,1 center,1 sub,all marked as such on avr and dvd-a player.The actual sound of dvd audio I compare to the best turntable and lp's.It is a huge difference in sound quality from cd or dvd.If you want to hear almost every spec of sound on the master tapes in 2 channel,192/24 some disc also have that option.The surround mix when done correctly,Yes "Fragile",Deep purple"Machine Head" and Fleetwood Mac are a few,are almost as good as consumer technology can produce.
