The evolution of a masterpiece, AK380 Description Features Specifications The purpose of Astell&Kern; is to keep the sound quality as close as possible to the original. The AK380 geared for the pro sound group and audiophiles who demand the very best. A masterpiece, we introduce 'AK380' to you. In order to become a device the professionals want, we decided that make a bold move which was to restart all processes from the beginning. The device the professionals want, now AK380 is the start. The light and the object are the main theme of the AK380 design. Any shadow of an object portraits the exact shape from the perspective of the light at that moment. The way of reproducing the true sound of music from digital formats is quite similar. Nothing more or nothing less. The design motif of the AK380 reflects our philosophy of music and sound. 32-bit 384kHz bit-to-bit Playback All of the AK380 s circuit design including the digital-analog converter (DAC) are ready for 32-bit processing to handle 32-bit music natively. Other products have traditionally used sample rate converter (SRC) method down sampling for playback. However, the AK380 is capable of playing back 32-bit, 384 kHz original sound without any down sampling.The result is the AK380 plays up to 32-bit, 384 kHz, any 24-bit music files, or double layer DSD 5.6MHz natively, without conversion or compression. We believe that the beauty of the design shall reflect what the AK380 can do with music. As different angles of light casts different shadows, different music will give you a variety of emotions.
