I´ve just purchased the UM3X but now I have a big question: which mp3 will suit better? I head that sansa have a good quality sound, but did Ill notice it? because I have all my music in mp3 and not in flac!!!
And I think I´ve wasted my money because I have my music in mp3 and not in flac and theres a lot of difference in quality sound with the lossles format =(
