Better means deeper, more clearly defined soundstage, it means cleaner/more distinct overall presentation - more easily heard stereo separation but more solid L/C/R across the soundstage - with greater refinement of top frequencies clear down to the bass. It means improved macrodynamics such that it seems someone turned up the level when it has not been touched. These are the results in every instance. It also gives the sense that you are hearing into the piece more and increases the corporeality of the artist(s).
