Please know I am not taking a defensive position for tape here; I just find this incredibly interesting. Even if 100% of listeners agreed with Mike's opinion in this post, the fact that mastered LPs are different than master tapes in being another generation away from the original and constrained somewhat by the lathe's capabilities and the physical limitations of the delivery media, this result might have a variety of explanations.
