It seems like every advance in digital music brings with it a debate about whether the latest format degrades quality in exchange for convenience. This was true when CDs first came onto the scene, and it's probably even more true today with MP3s and their digital audio brethren. Heck, even the advent of the gramophone in 1889 sparked debates over whether its sound quality was worse than Thomas Edison's phonograph. Last week, rock veteran Neil Young chimed in with his assertion that the digital music files we listen to today are of much lower quality than the original recordings.
