I'm not dreaming - these are great CD copies


I have an out of town friend who's given me some CD-Rs that he's made by simply copying music off of red book CDs. The music quality is extremely good - better than I'm used to hearing from my red book CDs. He's not an audiophile and has no idea what format is being utilized e.g. Lossless, etc.
Question - Can you really improve the quality of music from a red book CD by simply copying to some other format? If so, I'm boxing up all 300 of my CDs and asking my friend to copy make copies for me.

Do your homework Geoff, if a pits/land can’t be read because of a cd burn or scratch or defect, it’s substituted by the same last readable one, it’s a 50/50 chance of being right, that is simply what error correction is.

You’re getting warm. There doesn’t have to be a defect or scratch for errors to occur. Haven’t you been paying attention? 
What I originally said to which your twisting, is the burnt pit/land is harder to read and will cause more error correction to happen than the original retail stamped or moulded one.
As this photo shows, the difference is clear, that the original on the left will be easier to read and have less errors than both burnt middle and left.

And yet the sound is better on the copy.
Sez you and the OP, I have never ever found this, always the original has sounded less in your face and more musical.
