Thanks all- I guess where my thinking is concerns the reissues that seem to come up every decade or so and why some great mixes are not attempted to be repeated for the sake of getting something special into dedicated audiophiles hands for reasonable prices. There seems to be no no effort to recreate past triumphs, instead we get (sticking to the theme with Led Zep II as an example)- a terrible set of reissues per the late 80s/early 90's products. A series of great reissues for the Modern Classics versions of the early 00's (but the price on and availability of these is already astronomical with zero availability) and then most recently, the Jimmy Page engineered reissues of 2014- not terrible, but not great either- (Jimmy Page will never win any awards as a sound engineer). The Page reissues are available and reasonably priced. Any other good version is $200+ for a playable copy- certainly there is a business model that supports recreating highly praised mixes which could sell for $50-100 or so?
Why not copy the greats- vinyl LP question
When LP's are reissued, why are some of the great interpretations of classic music not just copied? For example Led Zeppelin II- I would love the RL-"hot" mix but cant swing $500+ for a less than optimal copy. Why is there not someone looking into recreating products like these?
