AAC or MP3 detail loss?

doesn anyone here play CD's burned from MP3 or AAC to audio discs? if so is all the detail still there? or do you lose some of the smaller details?
MP3 and AAC are lossy compression schemes. When you convert cd quality audio to MP3 or AAC, you lose information. That information is gone forever. Burning these files to an audio disc in no way gets that information back. You will most likely hear the difference unless you listen to the discs on a poor sounding playback system like a clock radio or through cheap computer speakers.
