Well, if DTS sounds better to you than PCM, then that's probably, um, how it sounds to you. There are far too many variables here to come to a conclusion. For instance, have you played back a decent range of examples of each type on a decent range of kit? If not then it might be something as simple as your music equipment is suited to DTS streams. Or the DTS music you choose to listen to.
The first thing that occurred to me when you mentioned hearing musical detail in DTS that was 'missing' in PCM, is the inherent differences between the two. DTS was specifically developed as a multi channel encoding method. DTS music/tracks are intentionally mixed and balanced as separate streams for the separate channels and different considerations are involved from mixing and balancing PCM for, say, a CD. It wouldn't surprise me, for instance, if the gain was wound up on a particular channel for a DTS track, and that might well emphasise, say, a vocal passage or a piece of guitar work that is less evident on a basic PCM recording.
Listen to a multi channel movie soundtrack on a stereo or mono sound system and hear how emphasised some of the lows and highs are, and often how muddy and unclear the voices can be.never trust a man in a blue trench coat, never drive a car when you're dead |
