What are you all doing to modify your cds?


I have tried pledge,cd rings and a green marker.Is there anything else that I am not aware of? Also who if anyone is still using the rings as they are hard to find?

Well, Sean and Ed, neither of your articles really PROVES much of anything. As a side note, if small scratches, fingerprints, smudges, etc., etc. effect the quality of CD playback THAT much, they have more in common with the lowly LP than some might lead us to believe! HA :-)
Hi again Sean, if you really think about it, what fun would it be if we were not off our rockers. In terms of these CD tweaks, I have no explanation whatsoever why they work. In theory, they really should make no difference. But they do. And, I'll put my ears up against any piece of test equipment any day of the week, for the simple reason, that is ultimately the criteria I use.

I also would have to question whether you can actually hear error correction. If I did hear it, I doubt I would actually recognize it. But, then again, there are some things I will probably never understand.

I mean, why did Kamikaze pilots wear crash helmets?
4yanx, just for clarification, I don't have any fingerprints on my CDs.

I always hold them by the EDGES when wiping them against my pant leg.

I look at it like this:

Audio reproduction is a blend of human perceptions and science. Through science, we can break down and assess what we perceive as humans. When science can fully explain ( never happen ) what we perceive, we will have attained "audio nirvana".

Until that point in time, i am of the belief that anything that subtracts, distorts or makes it harder to recover recorded data is a "bad" thing. If data corruption should occur, the reproduction devices ( digital in this case ) are giving me their interpretation ( through error correction ) of what they think i should hear rather than what the performer / engineers encoded onto the disk.

Since science can verify that this "interpretation of data" ( error correction ) is taking place, isn't it more logical to want to avoid this process at all costs ? Wouldn't this lead one to believe that, due to having the shortest path with the least amount of outside influences, we are obtaining the closest resemblance of what was put on the disc ?

Obviously, we have to take into account the meager performance of our entire system. My question is, why would anyone want to introduce a device that knowingly corrupts the data to a point of requiring greater effort to reproduce and / or "fake it" and then expect better results ?

In effect, error correction means that you are getting information second-hand. Why would you want to do this when you can go directly to the source and not have to worry about mis-interpretation and / or bits and pieces of information being left out ?

Audible or not, error correction should only be viewed as further interference of the signal with the potential for corruption of the data being recovered. It only seems logical to want to avoid the error correcton mechanism itself and any other devices / treatments that would cause the error correction mechanism to come into play. Kind of like treating the cancer and then avoiding anything that might cause it to come back. Sean

Sean, I am in full agreement with your thesis regarding the need to eliminate, to the extent possible, any and all error and that not doing so adds a measure of uncertainty, at the least. I am just not sure that all error is audible and that the 1998 article proves error. Wonder if any products have come online in the last 5 years that would change the author's mind?...

Ed, do you swipe those CD's to the pant leg even after your multi-tasked procedure. You see, though, Ed? The CD and LP have one more commonality. Typical cleaning approach! :-)
