There is NO DIFFERENCE in Quality between iTunes and iTunes Plus Songs
In a double-blind test, conducted by Maximum PC, they determined that there is no discernible difference between the 256kbps iTunes Plus files and the old, DRM-laden 128kbps tracks. Besides being a double blind test, different headphones were used (Apple’s default iPod earbuds vs. a pair of Shure buds) with 10 music professionals.
Personally I don’t care if there is a quality difference, I’m just glad the music industry is ever so slowly removing poisonous DRM from their media.
