How do you guys choose between CD releases?


This has been been bugging me for some time now and I'm wondering if any of you guys have a sensible way of choosing which release of a CD to buy. I buy the vast majority of my CDs on Amazon and too frequently have to choose between two releases of a CD e.g., 1990 or 2003. If there is a remaster I usually go with it, unless I'm warned off. That doesn't bother me, it's choosing between to releases with no more to go on than the year of release. You can't judge by sampling; you don't even know which release you're listening to, and Amazon reviews are seldom release specific. Should I just buy the newest, the cheapest or (gulp) most expensive? Any secrets? How do you guys decide?

The tone of my thread takes it for granted that there is a difference between reissues. That probably should have been my first question. Is this something that I should even be concerned about?
Generally the older the better. Early CD's had dynamic range even in pop/rock genres - since the 90's everything has become "loud" and compressed. The first releases of Toto sound great. The recent remasters sound bad - it is the same with most new remasters. Even the Beatles recent releases were crushed compressed and only the mono versions were any good...it is a sad state of affairs but that is what the record labels, producers and artists have put out.
Yes, I think it's worth considering. The newer release of an older album is frequently remastered, even when it's not mentioned. Certainly it's a bit unusual for newer release to be inferior. It seems to me that the standard has gradually improved over time. The imports are usually better than the domestic ones, but there's obviously no guarantee.

It's another matter when you already have an old release - I usually won't upgrade to a newer release unless I have a solid reason to expect a significant improvement.

This statement just goes to show how subjective audio is and how people perceive sound differently.I happen to think the new Beatles stereo discs sound very good.You shouldn't make purchases on someone's recommendation without hearing the product for yourself.Of course this is just my opinion and you know what they say about opinions.
