Ultra High Fidelity Music- Can you hear the difference? Anyone with the Ultra High Fidelity Sound option, if you want to compare the perceivable differences in sound quality between mere Super High Fidelity and true Ultra High Fidelity, download these 2 exactly the same tracks apart from the 96kHz & 192kHz resolutions. Put them on a USB stick to compare. Can you hear the difference? http://www.lindberg.no/hires/test/2L-077-stereo-192kHz_21.flac http://www.lindberg.no/hires/test/2L-077-stereo-96kHz_21.flac To download audio files username: 2L and password: 2L Not a huge difference, depending on your ears, but listen for the detail throughout the higher resolution file if you really listen carefully for the quietest sounds of the instruments in the first and then pick out those same ones in the second. In any case quite an atmospheric piece of baroque Norwegian folk harmonica and organ in what sounds like a cathedral. Bear in mind that this level of detail is impossible with the relative low resolution of Spotify, mp3/aac files & CD’s. Difficult to find whatever you want right now but HDtracks.com probably has the best choice until iTunes HiRes is available. Here are some more tracks from Norway to compare or even purchase if you'd like the entire albums: http://www.2l.no/hires/index.html Maximum resolution playable in the Model S is .flac 24-bit stereo 192kHz.
