I am hit or miss on Classic reissues.
Agree on II--much better than any vintage albums I have heard.
A word of caution: Avoid Classic's later Zep reissues--Houses of the Holy and IV in particular seem like a pale comparison to some of the best original vintage copies--way too much boosted mid range in the vox and guitars, and very little bottom end in the drums or bass--both sound a tad off for my tastes, especially on tracks like "The Ocean" and "Four Sticks", which really rock on the best copies I have heard. The best original copies have a truer magical soundstage with the fuller and airier drums and rock solid bass that you can really feel.
