Thank you all for the input.
Looks like I'll have to upgrade the whole lot,
there must b a dozen or so discs....
Warm Jets was (to my ears) the worst of the bunch and none of the cd's appeared as nice as the original vinyl editions.
His name escapes me, but the guy up in Portland Maine who re-mastered all of the old Roxy Music stuff did a superb job, there's just no comparison at all with the original batch on cd.... maybe wishful thinking, I was hoping for a similar improvement with Brian's music on EG and Opal.
Again many thanks!
