A Pocket Powerhouse
True to the core values of Astell&Kern, high fidelity sound lies at the heart of the SR25 MKII, delivering exceptional audio performance to a diverse
range of music lovers. The most distinctive feature of the Astell&Kern A&norma product line is its compact form factor. However, the SR25 MKII offers
more detailed sound than its predecessor, allowing the clear expression of each and every instrument and vocal note.
The SR25 MKII offers more versatile connectivity options with the addition of a 4.4mm balanced output for the first time in an A&norma player, LDAC,
as well as Qualcomm® aptX™ HD, which support and deliver true audiophile sound quality.
The SR25 MKII keeps everything we love about the SR25 and adds new design features. It will produce the best sound quality anywhere, anytime.
