Ripping Flac files from CD’s @ 24bit 192k is a simple and effective way to hear what you’ve been missing. This App also does a nice job of up converting Apple Loseless as well as any other file based audio. If you’re a serious listener I recommend turning off any of it’s volume adjusting or normalizing effects as these alter the original sonic intention of the artist/mixer etc… These effects are on by default so Audiophiles will want them off.
