I didn't go for the box set as I'm already well into getting them (and other Coltrane) on Classic or Speakers Corner and will wait for more of those or similar quality.
Where I have a classic/SC vs an ordinary quality Atlantic there is a resonable difference in terms of quietness, detail and dynamics (probably related.)
But a complete set on the very posh stuff will set you back more like three times the asking price of this box set. Bog standard Atlantic will cost about £8 a disc (in the UK) - pretty much the same as the box set if you got all 12 - with no bonus tracks. So if it's only a smigin better than the normal pressings then you're on to a winner.
Coltrane Atlantic: Giant Steps, Coltrane Jazz, My Favourite Things, Coltrane Plays the Blues, Coltranes Sound, Ole Coltrane.
Colaborations: Bags and Trans, The Avante-garde
Assuming one disc of extras (?), what at are the other three? I'm sure Atlantic would have done a 'best of' or two, but with the other discs this surely is redundant?
