How to find the good CD recordings?

I'm new to high end audio but have a decent system. One of the things I've noticed with this new (old) system, is that some of my CDs which I used to think sounded fine just don't sound all that good anymore while some of them sound great. A lot of these CDs are 30 years old and came from CD clubs (remember those?) and typical record stores.

I've noticed in particular that some of my Led Zep CDs just sound a little flat and a little shallow while some of the Pink Floyd and Rush CDs sound quite good. 

Is this just a matter of Floyd and Rush having higher production quality from the beginning? 

Would later "remastered" Zep CDs sound better? Is "remastered" always an indication of better or superior quality? Is it just marketing hype sometimes?

Anyway, with this new system I am inclined to buy the best quality recordings of any newer music I buy and possible replace some of my old favorites.

So is there a place on the internet where one can go to get reviews of the actual recording quality and not just the music itself. I don't see iTunes or Amazon as particularly useful here. At this point I am not interested in pursuing vinyl or high end audio files. I'm still just getting my feet wet and CDs seem like a cheap way to do that.

Any assistance much appreciated,

George

I can't speak to audio, but in the photography world dynamic range is a big issue from film to camera sensors to monitors to printers. We obsess over histograms which show not only the dynamic range (as 'x') but also the amount of luminance across the dynamic range (as 'y'). And you want each of your components to have the widest dynamic range capability.

However, the dynamic range of the finished photo (or print) nor the histogram even, tells you anything about whether it is a good photograph or not.

I suspect the same is true of music but don't know for sure. I'd guess the dynamic range is just one element of what makes a song sound good. Could be totally wrong.

For Gosta (and others): For what its worth;  be sure when checking the DR database that you are on the Specific release: (if near or complete data is avail), the barcode, origin of pressing, the date, etc, as there are many variants of album/compilations (as you know already), and of course not every recording is available unfortunately.  But you are correct in that some SACD releases/pressings are and can be terrible.  I found that out later as I have/had (copies of specific CD's/SACD's that attest to that.  For the most part, the database is what it is, and of course your system will show (or hide) the shortcomings in a respective recording/mix.  I don't believe that if a recoding/song(s) are inherently loud, has any adverse effect on the rendering of the dynamic response logarithm.   Although many LP's are decent, VG, to excellent, there are many terrible LP mixes also.   If it's a poor recoding/mix, then it will show as such.  I also agree with you on there yes to be a direct correlation to the "older" CD pressings generally tend to be more dynamic, as well as many Japanese and EU pressings.  Keep listening and, Enjoy the Music!
Cheers.

I looked up my Zeppelin CDs on the dynamic range database. My 1990 Zep I Diament did not rate very well, but II and III by Diament and IV by Page all rated very high.

I’m going to look for a Physical Graffiti CD next. I’ll use the database but open to suggestions as well.

The Zep CDs were not released in chronological order, but you should be looking for the 1986 and 87 issues. There are the early Target issues from Germany, 1985; excellent SQ, very transparent, but only LZ IV $ HOTH were produced.

The early releases should not have a barcode. And a first release is a nice collectable having a solid silver inner ring, as opposed to transparent plastic.

Timely tip: all things being equal CDs with a solid silver disc around the spindle hole sound worse than those with transparent rings. Don’t believe me? Use a Dremel tool with the abrasive attachment and remove the solid silver layer around the spindle hole. Theory - The solid silver disc is highly reflective of scattered laser light, thus produces more noise.

I guess that’s possible since it’s often advised to use a coating or cover the the reflective areas of CD’s.
But as I stated earlier, finding the best quality CD pressing is a crapshoot. Some of my silver ring CDs have outstanding SQ. However, first issues are not always the best sounding, even when they have the transparent inner ring. I have some late issues that sound better.
I’m a collector of CDs and vinyl so I like owning first pressings, including the silver discs. And they do maintain their higher value.
