Are MP3 files worse than CDs?
I have an extensive music collection – mostly classical and jazz – on CD. Recently, I began importing them to iTunes, so that I can stream the music round the house, rather than simply listening to it in my living room. Is there any compromise on quality in just buying the music from iTunes, rather than CDs? I have heard that MP3 music is ‘lossy’ and some quality information is discarded during conversion.

There are still reasons to buy CDs (as a backup, or for the inlay), but better sound quality is not one of them. The AAC format used by the iTunes Store only discards the information your ears are least sensitive to. If you can’t tell apart a JPEG photo and an uncompressed image, it’s unlikely you’ll notice the difference between iTunes Store and audio CDs either.
Most people find it hard to tell apart CD and iTunes Store music.
