Classic rock: best remasters


For rock fans just curious what remasters, recent or otherwise, were a quantum leap over the original vinyl or compact disc release. On the flip side, any original CD releases that are still competitive? Not interested in imports, SACD, etc. Thanks rockers!

I like some of the UK Deep Purple remasters; especially 'Machine Head.' The original US CD is garbage.
Zep II and HOTH are two of the better sounding Zep releases...so I have never persuaded RL pressings...its Zep...it ain't Opera
I have the machine head anniversary ed that the bassist did...including a remix version... Sounds good 2 me...I have orig UK vinyl...never heard WB domestic...tho some like it.
