A&norma sets the standard of Hi-Fi audio for novice audiophiles. The SR15, the first model of A&norma, is the entry point to the Astell&Kern Hi-Fi Audio experience which has been lauded by audiophiles around the world. A&norma SR15 was inspired by a composition of interconnected rectangles. The slight angle and precise, mindful alignment show the empty space and tones that fills the space. From any angle, or either hand you hold your device, it does not hinder the display screen and offers the best possible grip. The rectangle on the front connects to the glass on the back plate. The rectangular reflection changes its shapes based on different angles of light, creating 3-dimensional space.
