Query: improved sound but still not perfect

I use my digital voice recorder to make relaxation CDs for my patients so that they can practice the skills I teach them. This microphone definitely helped improve the quality of the sound; however, it still comes across somewhat distorted. One of my patients mentioned that it sounds a step up from the bootleg CDs you can get on the streets, which he believes was an improvement from the CD I made him before (without the microphone)- but it's still not great.
