Star Trek  (TrueHD 5.1) - Reference
It is true the volume knob will be spun a few turns to the right for this title, but I've never considered volume changes as part of the equation to ratings. Dialogue intelligibility is foremost and is my basis for making any changes in volume settings; I rate the track by how well the other sounds go with the voices, and I certainly have no qualms with clockwising the knob.
Volume setting aside, this track is easily
my favorite on BD so far this year. With a top-notch sound design by the excellent Ben Burtt and a tight, aggressive mix, this TrueHD track certainly will knock the socks off a lot of feet. The surrounds are heavily employed, and the panning is seamless. Dialogue is very clear and well-recorded. Dynamics is incredibly wide, never faltering as some of the reference films do. And bass is deep and amazing (OMG, those warps each and every time made me wince due to their power!). Even punches pack... well, punch!
I love the sound design here as well. Just as immaculate as the aesthetics employed for the visuals, the sound design is every bit as clean. It employs sounds ranging from the deep end to illustrate power and foreboding doom to the shrillest of shrills that capture the essence of advanced technology. Though action-packed from beginning to end, the design manages to make the final scenes a refreshing listen. What's more, the music by Giacchino really plays on the psychological turmoil in the main characters as well as accentuating the action onscreen; brass is often heard to really amplify the sci-fi feel. I must say I didn't enjoy the music soundtrack alone, but coupled with the film, the music is memorable (that damn motif is stuck in my head now).
Star Trek is reference and an excellent audio demo track.
