I use to burn cd-r's directly from the source and I heard clicks and other occasional distortions. I now extract the music from the source and save it onto the computer. I then burn it a 1X (the original speed) and they sound excellent. Also some brands of cd-r's cause problems with auto and high end cd players. I find Sony CD-R's to be the best and most reliable for audio. Memorex is not very good, TDK are blue in color and some audio cd players won't recognize them.
