This used to be a problem for me as well until I noticed the audio bit rate. Of course, for the best mixing quality, we mostly prefer to track in 24 bits, but cd audio is always 16 bit. What happens is that when Sonar detects you're trying to import 16 bit wav and your project is at 24 bit, it will SRC the the wav into a 24 bit copy despite your import settings.

The workaround, of course, is to set the project to 16 bit while importing. Sonar, however, will peg the project at 16 bit so if you want to work at 24 bit, you might have to delete the imported 16 bit wav when you're through with it or... you might want to upsample the 16 bit file prior to importing.
