Best and Worst Reissue/Remaster CDs

Lots of remastered CDs are showing up these days. Some are wonderful, others only ok...

I loved the Dead's box set (Europe 72 is better than the record and lots of new stuff included). The remaster of Yes Album was great on EastWest (Japan LP type reissue), but their release of Close To The Edge was harsh. Steve Stills Manassas was much improved in HDCD, but still somewhat limited by the original tapes. Creedence never sounded better. It seems to me that it is all so unpredictable...

What reissues made you weep (either in agony or joy)?

Dave Clark 5 ,remastered by Dave Clark his ownself.Sounds like it was remastered by a deaf guy,which it was(in one ear anyway).My 36 year old vinyl that I used to toss around like a frisbee sounds better than this digitaly remastered piece o junk.
Sugar, as you say, Decca, but many of EMI's "great recordings of the century" are also good contenders. Sony's reissues are quite good, too. DG's early digital recordings invariably sound disastrous but I find their "originals" are somewhat better (less inaudible, if you will) glass violins & all...

Another terrible re-mastering is D. Purple "Made in Japan" -- I have the vinyl and, any comparison is a waste of server space!
Thanks folks. I knew this would pay off... Just ordered Nilsson Sings Newman and Zappa One Size Fits All. I decided against Dave Clark even though I wanted my wife to experience it. Hope to hear more!
I agree there are some very good EMI releases. But I also have bought some recent ones that were not as good as the earlier release. I bought the new one because the Penguin guide people thought it was a lot better. This has happened a few times recently with them, so I no longer use them as a source for recording quality only the performance quality. They must have budget equipment.
