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.

You will find others who agree that some copied CDs can sound much better than original.
It isn't some other format - it is the burning process that can lead to better results. The store-bought copies are stamped which, apparently, isn't always as good as burning. I have noticed this phenomenon several times but it seems it doesn't hold for all cases(?).

It is my opinion the reason that "burned" CD's sound "better" is that some of the high frequencies are lost during the process, thereby removing some of the CD glare in playback on some systems which have a bright sonic characteristic.

My hypothesis could be checked out if one is fortunate enough to have access to a dual sweep oscilloscope.
