I do not know anything about modern audio electronics, so I apologize in advance for asking dumb questions. I have several hundred classic rock albums (from CD) stored in an Apple computer in loss-less files (I do not know what kind, just that they are not compressed like MP3 files). I want to get a device that I can put these albums onto (or at least a bunch of them) and play them through head phones or connect to the auxiliary input of my car. What kind of machine should I get? Do I need to keep the music in those lossless files to play in a car? Thanks for your patience with an old hippie.
