Easiest way to burn multiple CD copies?

I have some audio files (aiff) that I created in Amadeus Pro. To make copies of these I am opening AP and burning CD's from within. Seems unnecessarily awkward. Is there a simpler way to do this? I have read that you can use Disk Utility to create an image and then use that image to burn a CD however when I try to do this the option grayed out and the message that DU cannot make an image from an audio CD.

Thanks,
Richard
