Astell&Kern is the ultimate source of digital music, able to bring MQS (Master Quality Sound). Currently, original music performances can be recorded digitally, almost exactly as they are performed. This is made possible by the advanced recording technology available; however, these high-quality recordings are primarily played through streaming services or inferior sound formats like MP3. MP3 compresses audio files heavily to save space and make it convenient, therefore listeners often only hear an inferior version of an original recording. The company’s goal, which they have certainly achieved, is to provide music lovers with an original and natural sound quality that is free from any distortion.
