HDTRACKS sample rate


I downloaded the free sample from HD TRACKS, which has a sample rate of 24/96 to see what the fuss is about. When playing it from my laptop to my Marantz SA8004 USB input the sample rate reads 16/44.1 The Marantz is supposed to accept inputs up to 24/192. Anyone know why it's only playing at the sample rate of 44.1?

If you are using iTunes for playback it does not auto switch sample rates. You have to manually change to the 24/96. That's why a lot of people use a third party playback software like Audivrana and Pure Music (Mac) or dbPoweramp (Windows) for playback because they will auto switch.
