I own the Anthology and the 2004 editions. I personally find them fine enough to listen to because well...what other choices do I have. I'm not about to run out and buy the LPs or anything. I certainly hear some tape noise here and there, some slightly jarring editing decisions and the occasional master (or copy of a master) error. But it's nothing that can totally draw me out of the good feelings I get when I listen to them. Yes these errors are correctable and in many cases shouldn't have happened in the first case but......damned if anything I can do will change that. Someone like GoodMusician (or perhaps GoodMusician himself) needs to make contact with those involved in the industry that truly care about a definitive, as close as fuckin possible to perfect, release of these scores.
Interesting posts though GM.
