The Xclef HD-800 builds upon the massive feature set of the HD-500. Using a tiny 1.8 hard drive the HD-800 is almost half the size of the Xclef HD-500. Along with smaller physical dimensions the HD-800 includes Ogg Vorbis and WAV playback support and a dedicated Optical Line In Socket. With a sleek new case design featuring glowing blue right hand side buttons and an intuitive jog dial on the front of the player the HD-800 is supremely easy to use. Sound quality is just as good as ever with even more EQ modes and of course M3U playlist support by default.
