The awful truth about CDs, do they have the same shelve life as LP's ?


The answer is properly not. Recent studies have shown that the chemicals used in their manufacture of CDs have reduced their life expectancy to ten years, not all but many, as per Paul Mcgowans email. The suggestion was given that if you have suspect CD's they should be re-copied. But my question is how do you identify these? I can tell you that I have a great deal of LPs and I can play anyone of these with great success and some are 40 years old. This no doubt would give some audiophiles another good reason to hold onto their belief that LPs are the way to go.

I'm sure there are a few out there, but it is rare for audiophiles to not own at the very least a CD player, as there is a lot of good music that is not available on vinyl.
Yes, their systems will be optimized for vinyl. On the other hand, there are a lot of audiophiles who don't own turntables.
A very good AD converter can be had for a list price of $399, the HRT Linestreamer+. Go up to $2k and you have multiple choices, including Benchmark and many others.  PS Audio is closing out their current phono stage with built in AD converter for $1k.
I have digitized many of my favorite LPs, for convenience, and to preserve them. It is nice when wanting to play one or two tracks off an album, to just click on a few links, rather than having to cue it up. Of course digital files aren't going to give you the same experience as holding that album cover in your hands. I have vinyl that I purchased over 45 years ago, the records themselves are in mint condition, which I find very impressive, as they have been played on five different turntables with the first two, not being very good. Nobody is using a BSR mini changer and bragging about how great it is. But, surprisingly, those records, are in mint condition. The same can't be said for the covers. Glued seams have come apart, even with careful handling. So those albums have been digitized, and only get played rarely, as the digital copies through a really good DAC, sound good, very good.

As to dyes, I believe he was talking about the labels. There is no standard I am aware of with the materials used, and looking at them, the different textures, and colors, makes me think that some probably have dyes in them.
Read the other posts where they talked of the labels changing color.

When I mentioned enthusiastic, I was referring to new products, and differences that may be much easier to hear on their reference system, than on a mid level or entry level system.
Hi,

My 2 cents. I have a few commercial CD's from 1985 that developed spots/deterioration in their inner layer(s). I cannot feel then on the outside layer.

The were manufactured in USA by WEA Manufacturing Inc. record label is Elektra/Asylum. 

I keep all my CD's in binders. So far it is a real minority that are damaged like this. My opinion is that it all depends in the quality of the manufacturing.

With CD-R's (mixes), I have several that have gone really bad with time; to the point that I have to throw them away. It probably was the qualityof the CD-R materials back then.   
I had only two of my CD collection "loose" parts of a few tracks. Yup some music disappeared. All the rest are fine.
I have around 300 CDs.  They are stored indoors, in sleeves, not in the car. Truthfully, I don’t listen to them very often any longer. But I do have a few that have deteriorated. When I’ve played them, they sound sort of like an album with something sticky on them. Like a "fuzzy" sound in the playback. It’s a few... less than ten... but it’s still there, for sure. Someone above commented that you can just rip them onto a new CD/R, but that doesn’t work. It just records the "fuzzy" sound.

So, I think that like anything else, they aren’t truly a "forever" medium.
