Closer to Original Sound After successfully launching the AK100 and the AK120 models, They asked themselves, "What is the ultimate sound quality?" After much consideration, They decided to move a step further with their goal, which is to deliver the sound "exactly as the artist had intended" for them to hear. Moving from the AK100 to AK120, Astell&Kern decided to provide a Dual DAC setup to create better left and right channel separation with clearer sound quality. They thought that the Dual DAC setup would be enough, but while developing the AK240, They felt the need to further improve sound quality in order to accurately reproduce the original sound recording. After countless hours of research and testing, they were able to find the answer. The answer was to create both a balanced output and native DSD playback through the Dual DAC setup. What is DSD? DSD (Direct Stream Digital) is a digital audio file format originally developed for SACDs (Super Audio CD). Regular digital audio file formats such as PCM (Pulse Code Modulation) is separated into 65000(16bit) to 16700000(24bit) of information on the Y axis and 44100(44.1kHz) to 192000(192kHz) across the x axis for digital signals. DSD files have 1bit (0s or 1s) for Y axis and is separated into 2800000(2.8MHz) to 5600000(5.6MHz) of information for x axis. Compared to regular audio CDs with 16bit/44.1kHz PCM format, SACD's recording frequency goes up to 100kHz and the dynamic range goes beyon
