Broadcaster and author Ma Shih-fang's Music 543 formed around an online community of music fans. Its sound is a more mature one. Its productions include a series of Golden-Melody-Award-winning records by Sandee Chen as well as the ambitious Indie Soundcheck Project.
廣播人兼作家馬世芳的「音樂五四三」，則以網路音樂社群起家，品牌風格較為成熟取向，旗下作品除了歌手陳珊妮曾獲金曲獎肯定的系列專輯外，還包括頗具理想性格的「IS（Indie Soundcheck）計畫」。
