With the development of the times, dramatic changes have taken place on the methods of recording sound, from wire recording at the earliest time, to reel to reel tape recorder, LP record, and then to CD, DVD in digital era. For now, digital audio formats which represented by MP3 have become the main stream. However, due to the convenience of obtaining and recording sound, after the procedures of recording, transforming, compressing and format-changing, the sound would be no longer the true and original one of the live scene. Fortunately, after long periods of research and development, FiiO Company finally succeeded in making one high quality portable music player which can support five main lossless music formats and original master copy at 192K/24BIT, aiming to help music lovers to find the ever lost sound.
