Moryoga: I think the 'muddy' sound of LZII (at least on several tracks) is due to the huge amount of crude processing done when the album was originally assembled- you can hear the overdubs and the layering of different tracks- it is very evident on the 'RL' of II where a track with heavy processing, like 'Whole Lotta Love' seems to suffer from generation loss due to all the gimmicks. There are some web discussions and articles about how the album was made that support this.
I still haven't listened to my new copies yet, but hope to do so soon.
