Say, you rip your favorite song from your favorite CD into your computer, using any of the lossless formats, then transfer this file into your digital music player. Now if you want to play the song in a high end home audio system, what connection in between, or what equipment in between, or what digital music player, can make sure the sound quality will be as good as from the CD? Without the use of the computer, of course, and for the same logic, without any wireless streaming device. For example, maybe an ipod dock with optical audio output?
