I finally took some time before heading off to bed to scan the 2 copies of Holst - The Planets, well only Jupiter, the Bringer of Jollity. It does show the difference in loudness very well. The top is the Andre Previn version apparently done as all digital(DDD) according to the jacket. The bottom is from Mehta's version which was Analog to Digital(ADD). Other than needing to turn up the volume on the Previn version I can't tell any difference.
I had my SPL meter out to check for any difference in Dynamic range while listening on the M80s and they both run in the mid 50 db range for the most part.
