Copies Better Than Originals?

A copy of a CD can indeed appear to be better than the original. The reason is simple: the Red Book defines that the bit stream from an audio CD is processed in real time. In essence, this means that any time there is a read error, error correction needs to kick in, which will degrade the sound to some degree.
Conversely, if the copy machine actually does a CD-ROM read of the CD , that is, it builds a faithful copy of the CD in memory and then writes the copy, the copy may sound better when played in Red Book mode; error correction will not have to work as hard on the copy.

One might be tempted to ask, "If a copy was somehow better than the original, then where did the copier get the knowledge/information to add anything, without that that information being part of the original in the first place?" If in fact, the original did not contain the information that is added in the "better copy", then how can it be considered a "copy"? It cannot. It can be considered a synthesized enhancement, like an airbrushed Playboy centerfold.

It is totally impossible for a copy to exceed an original for content quality. As I stated above, to do so would require the addition of information or material that didn't exist in the original, and therefore anything added would simply be "made up" out of whole cloth. It can be "touched up", enhanced, restored, etc, to make it more "acceptable" to some, but never exceeded.

I don't remember the exact description but this was discussed in Sterophile a number of years ago. The author stated that copies had lower jitter and this could account for the improved sound over the original.

In my case I experiment what mapleshade did, they use
this mikro smooth to the surface of the blank cd,
then I put the original to the bedini ultraclarifier,
then start burning in, guess What ? One on the cd
that is so bright and I cant listen, suddenly, it
I can listen to it longer. IT WORKS.

Pioneer has been known to rewrite the laws of physics. About 25 years ago they advertized a head shell that was low in weight but high in mass.
