The rapid development of audio technology, so that ordinary consumers can not keep up with the sound of market development trend of knowledge, in the face of emerging new products know what to do. For example, the recent appearance of 24Bit CDs and superalloy CDs in the CD record market is different from the original 16Bit CDs, aluminum film CDs and 24K gold film CDs.
