How different is the audio quality for the harry potter special edition blu rays?

[James_Younger_Gang]

I know there are already threads for these new target exclusives blu rays, but I haven't read about audio comparisons between the first blu rays released with pcm audio and the new ones with dts master audio. Yes I know the audio tracks have different names. Some people have said the audio is crisper and punchier in the new editions, but how much of an improvement is it? Or is it just slightly better? I know that the video quality is the same. Pardon my asking so much. I'm not sure if I want to collect the blu rays again based on an audio difference unless it's brutally great.
