I took a bunch of my cd's and had to convert them into my computer as a wav file and then download them onto my mp3 player. It seems with quite a few of the sonds the sound quality is quite a bit worse.

Now I got an ipod. I bought a few songs on itunes and took all my converted wav files on my computer and imported them into itunes. When I listen to my ipod I can instantly tell what songs were purchased on itunes and which were converted wav files.

My question is if I take the original cd and import directly into itunes will that make them sound better over the wav converted files? It's really time consuming to do all of them. Will it sound the same as the one's I purchased on itunes?
