A preliminary word of caution
:THE BOURNE ULTIMATUM
HD DVD's Dolby TrueHD soundtrack has a known issue of triggering D.R.C. "ON." I did not know this until I read about a similar issue involving the IRON MAN
Blu-ray's Dolby TrueHD track. I immediately relistened to the final chase sequence of THE BOURNE ULTIMATUM
, turning D.R.C. "OFF" manually after I had started playing the scene, and this greatly improved dynamic range, impact, surround usage, and LFE presence.
Please, consider this when comparing the Dolby TrueHD and DTS-HD Lossless Master Audio soundtracks, especially if doing such from memory.
Onkyo users, seek thee out the Late Night Button.
