do burnt CD copys sound as good as originals?

No difference...a digital to digital dub will cause no loss - you can make 1000 copies if you wish. Bob Katz and many many others have tested this.

If you are convinced that you really hear a difference then you might question the impartiality of your own skills at detecting differences between other components (amps, cables, IC's etc.).....it seems you have been "got" by the placebo effect (your expectations have framed your opinions rather than your observations).

Like Arni, I think burns can sound better. I've ripped originals to Itunes while my Mac is powered by my PS Audio 300. Then I've burned to either Memorex black or gold Mitsui's that have been pretreated with Auric Illuminator using an external LaCie burner powered by the P300 once again. Burn speeds are no faster than 4x. When I take this amount of care, they often sound superior to the original cd. The comparisons are made to an Auric treated original FWIW.

A number of years ago I remember reading an article as to why copies can sound better than the original. I think that it might have been in Stereophile. I don't fully remember what the theory was, but it sounded reasonable. I think that it had something to do with the transition from pit to plateau on the data layer of the original being better defined on the copy. Certainly there are many people who report that copies sound better, although just as many report no difference.

To say that there is no difference merely because a bit for bit copy is being made is difficult to sustain. This argument should apply to all things digital. With this logic, all CD players should sound the same, and all digital cables since it's just bits that are being moved around. Well, we know that's not true, because the timing of the bits as measured by jitter can cause CD players to sound different. So more than bits comes into the equation.

I suppose the best thing to do is to give it a try and see if it works for you.

There actually is no difference in a digital recording and a digital copy of the same digital recording....jitter and different sounding CD players come from other factors like the differing clock accuracy, power supply and D to A circuitry between players. This has been proven many times over. Digital data storage is the basis for banking, communications and a whole host of modern technologies...digital data correctly copied (without errors) will perfectly preserve the original digital data - no loss and no difference.

That all makes sense, Shadorne, but I think that some of us have had contradicting experiences. I have a CD burner device, a Panasonic thing with two drawers. It's about 6 years old. When I use it to make compilations, they sound decidedly inferior to the originals. How come?
