Ok, as mentioned in the "Listening to Now (In Surround)" thread, I just finished a thorough-listen through to both the mastered and unmastered 5.1 mixes of "Aqualung" to compare and determine which one I like better, and for me, the winner is…the mastered version.
Now to explain:
The unmastered version was not as much of a revelation as I would have originally thought, by that I mean that Peter Mew's mastering changes were not as detrimental to Steven Wilson's mixing as we were all led to believe. Yes, overall it is louder, but that's not really a bad thing in this instance. It's also brighter, but again, it's actually not a bad thing in this instance. Both changes may be unnecessary (to some), but for me, the changes do not destroy the quality of the album or Steven Wilson's mixing, especially since the mastering helps to further liven up the sound of "Aqualung", which to me has always been a very 'dull' sounding album.
Plus the mastered version is lossless. 'Nuff said there…
For those who can't afford the now OOP Blu-Ray set, I honestly think the newer unmastered set will be just fine for all of you. Both versions are very listenable and enjoyable, so just get one version one way or another and enjoy it!
