The thing about digital recordings with a large dynamic range is that you have to turn the volume up. They are designed to be listened to with bit of welly. And I mean turn it up to where the peaks are actually frightening in scale and power. Not always possible in a domestic situation hence the 'polite' sound. Brand X recordings have a good dynamic range on digital and although I don't have any Roger Waters I suspect the same is true of his recordings. System has to be able to deliver it without the amp clipping or the speakers straining though, otherwise it will just sound 'loud' and unpleasant.
The vinyl versions are likely more compressed, especially in the bass, but this will give punch at lower volumes in the same way that a loudness button does.
