*All of music pieces are stored in the form of DSD (dsf) files. Video content is not included.
*Before playing back, copy the music data to PC, USB hard disc drive or NAS. Because a Blu-ray ROM is used as a playback medium, a Blu-ray disc drive is required to read and copy the music data.
*To enjoy its prime sound quality, a digital-to-analog converter or the like, which supports each music data's sampling rate and bit rate, is required.
*The discs cannot be read or played on conventional Blu-ray disc players.
