What CDs to buy

The Blue Note XRCDs are outstanding. I was just listening to Hank Mobley's Soul Station, and it is superb.

Also, it is well known that some, but not all Japanese remasters are excellent. They can be expensive, but in my view worth the retail cost in at least some cases, I believe. For example, I grew up on '70s funk and soul, and of course there were plenty of less than stellar recordings. But the Japanese remasters of, for example, the early albums  of Tower of Power and Earth Wind & Fire, are really excellent.

SuperTramp, Brothers in Arms (Dire Straights), Jennifer Warnes, Art of Noise (if you like them).

The best advise I could give you is to spend some time doing research before purchasing certain CD's. There is a vast difference in sound quality based on the particular iteration of the disk. In a lot of cases, older is better, but even that is not a hard and fast rule.

This website is invaluable in making a decision.

The site is a library of the dynamic range of each version of a particular disk.

IMO, a lot of CD's that came out in the 80's sounded like crap as far as sound quality; not surprising as it was a new technology - Midnight Oil and Iron Maiden come immediately to mind as 80's offenders, but there are many, many more, and the remastered versions of these releases sound far superior to the 80's releases, at least to me they do. 

Usually any of the latest remastered remixed CDs sound great like the Beach Boys, Beatles Sargent Pepper, Revolver, White or Let it Be, much cleaner sounding, great bottom, middle and highs as well as instrument and vocal separation.
