In theory they should both sound the same since it's getting turned into PCM by one device or another. But in practice it's possible that some variables *could* affect the sound depending on where it happens. For instance, jitter might affect PCM over HDMI differently than bitstreamed compressed audio data. It's also possible that dialog normalization and other "features" of TrueHD, or some sort of additional processing, could be applied in one case but not the other (or applied differently) depending on your gear and set-up.
Since I can only decode to PCM and hear it that way I can't compare myself. But I can say that the decoded 5.1 24/96 TrueHD on the David Matthews BD (sent as PCM over HDMI to my Marantz) was beyond belief.
BTW, I bought a Marantz 8002 with HDMI 1.3 and built-in decoding of TrueHD and DTS-HD MA so I could keep my options open in the future: the PS3 is not the last BD player I'll ever own and I'd like to hear it both ways and decide what I like better with my next player (bitstream versus extraced PCM). I would encourage ANYONE buying a new audio receiver to do the same: don't get ANYTHING that doesn't have HDMI 1.3 *and* internal advanced audio decoding. Keep your options open... you might have that receiver for a long time (had my last one for over 5 years) and you want to make sure it can accept and decode these new formats to ensure that you're not going to miss anything going forward.
