I have a lot of music that I downloaded from iTunes. It remains in its original format. Lately, Ive been wondering if its worth converting these iTunes albums to Apple Lossless or aiff. Would decompressing these recordings be of any benefit, do you think? Or is it a fallacy to think that I can add quality by choosing a lossless format? Would I gain by doing so? It's a fairly eclectic collection but top heavy with Jazz.
