I picked up the DVD-A of Stage, by David Bowie. It has three sound options: 5.1 DTS 24/48 2.0 PCM 24/48 5.1 DVD-A 24/48 Now, my music listening is two-channel. It's a choice I made a couple of years back when I got weary of 5.1 "showy" mixes and decided to simplify my life. Here's my question -- is there any audio quality difference, aside from the multiple channels, between the DVD-A track and the PCM track? I wouldn't even ask, except I have a DVD-A of On The Beach by Neil Young that has a stereo 48/192 track that appears as DVD-A rather than PCM in the little readout thingy on my DVD player. Does PCM as a format not support 48/192? Is this just some bugaboo of my player? Am I losing something (aside from the multiple channels) by selecting the PCM track?
