* Uncompressed (PCM) vs. Lossless Audio (Dolby TrueHD/DTS-HD MA) - Again comprehensive but worth a read:At least one professional Hollywood sound mixer has described Dolby Digital Plus at 1.5 Mb/s as audibly transparent to the studio master.

From that article:
That is SO true!There's a well-known principle in auditory research that has shown that listeners typically perceive a recording played back at a louder volume as better in quality than the same recording at a lower volume. That's because the louder the playback, the more pressure generated by its sound waves. At a difference of just a few decibels, the listener may not necessarily be able to tell that one track is being played louder than the other, but subtle sounds in the recording will suddenly start to vibrate their eardrums more forcefully. The result will be that the louder track seems to have more clarity, breadth, and "impact," when in fact the only real difference is that it's being played a little louder.
