    Thanks. Didn't read it start to finish, but the gist is people can tell the difference between high-res, and CD quality music.

    It does state that if you're trained to listen then you can hear the difference

    The reality is you must be familiar with the music in order to devise a comparison

    Thanks for the cliff notes fellas there is no way in hell Im going read all that.

    Oh, Listen here mister. We got no way of understandin' this world. But we got as much sense of this bird flyin in the sky. Now there is a lot that bird don't know, but it don't change the fact that the world is happening to him all the same. What I am tryin to say is, is that the course of your life, well its changing, and you don't even see it- Forest Bondurant

    Yes, it states if you are trained then you can better tell the difference, but even without training there still is a statistical difference in being able to hear a difference.

    I figured DK would feel vindicated. B)

    It's really not that bad of a slog (to read through) and summaries are made at the end of most sections.

    Finally got around to reading this. A common characteristic of many of these type studies is that they do not directly relate to the stereophonic listening experience. This is particularly true with regard to listening to only snippets of a recording.

    Some notable quotes:

    "The results are striking. The training subgroup reported
    an overall strong and significant ability to discriminate high
    resolution audio. " p. 371

    "The International Telecommunication Union recommends
    that sound samples used for sound quality comparison
    should not last longer than 15–20 s, and intervals
    between sound samples should be up to 1.5 s [78], partly
    because of limitations in short-term memory of test subjects.
    However, the extensive research into brain response
    to high resolution content suggests that exposure to high
    frequency content may evoke a response that is both lagged
    and persistent for tens of seconds, e.g., [22, 48]. This implies
    that effective testing of high resolution audio discrimination
    should use much longer samples and intervals than the
    ITU recommendation implies." p. 371

    "It is well-known that the dynamic range of human hearing (when measured
    over a wide range of frequencies and considering deviations among subjects)
    may exceed 100 dB. Therefore, it is reasonable to speculate that bit depth beyond
    16 bits may be perceived." p. 372

    "When subjects were trained, the ability to discriminate was far
    more significant. The analysis also suggested that careful
    selection of stimuli, including their duration, may play an
    important role in the ability to discriminate between high
    resolution and standard resolution audio. Sensitivity analysis,
    where different selection criteria and different analysis
    approaches were applied, confirmed these results." p. 373

    I laughed out loud when I saw that the first and only responder was someone who has been banned from numerous audio forums.

    Good point Ray, although I was expecting Jinjuku. :)
