I'm about to convert my 1,000+ CD collection to digital, and since I'm a mac-user, should I select ALAC format? AND is the Cocktail Audio - X12 - CD Ripper a good buy, or even a necessary buy, to accomplish this? What else would I then need to end up with the best listening experience? Would I still need, for example, to invest in something like Amarra, Audirvana or Pure Music?
