Just told my buddy that 24K gold CDs don't sound any better. He says feels like he's been lied to. But they're only $30!! |

LOL, I never heard of this. Really? Gold CDs? We emailed about this a month or so ago  You said that a person could prove that it wasn't superior by burning a copy to a regular CD-R and doing a bit-for-bit check. |

Does anyone use checksums anymore? We used to use them to check ROMs, PROMs, EPROMS etc. It's not 100% but the idea was if the sums were the same, the probability was good all the data was correct or the same.
I've heard some CD's can physically loose data due to aging or some type of deterioration. Do these gold CDs have any advantage in that sense or is it really just a bad joke...(on the buyer).

I used checksums all the time to check the integrity of ISO Image downloads for the Linux distro I used to work with. Funny thing was after years of LOTS of downloads of beta releases, etc, I never ran into a corrupted file. Maybe I was just lucky? Still use it on the rare occasion a new version is released or there's some new distro I want to check out.
CD rot, though rare is a real thing. I don't know if the gold ones are really any better but I suppose they could be. The main deal is the aluminum oxidation due to various factors so gold should be more stable in those circumstances.

According to mastering engineer Bob Katz's book "Mastering Audio: The Art and the Science", the shelf life of a modern CD is on the order of a century or so, so I wouldn't be too concerned about that. The argument from the audiofools is that the gold CD somehow sounds better. Also remember that two cd rips that are NOT bit for bit identical can sound exactly the same due to the CD's error correction process, which can in many cases restore the original data even if it is read incorrectly from the disc. For this reason it's actually possible to burn a copy of a CD that has less errors than the original |
