Astell & Kern A&norma SR15 Portable Music Player Sounds as Distinctive as It Looks: Features Dual Balanced MasterHIFI-Class DACs, Native DSD and 24-Bit/192kHz Playback, Quad-Core CPU

A portable high-resolution music player from industry leaders Astell & Kern for well under four figures – and that still boasts many of the company's signature cutting-edge technologies? Designed as an entry-level model, A&norma SR15 is anything but, featuring dual balanced Cirrus Logic MasterHIFI-class CS43198 DACs, native DSD and 24-bit/192kHz bit-to-bit PCM playback, a quad-core CPU, and a USB-B input. Inspired by a stack of interconnected rectangles, the distinguished-looking A&norma SR15 touts a tilted 3.3-inch TFT LCD display screen that allows stellar visibility from any angle as well as easy, interference-free hand-held grip for on-the-go use. Its feather-light 0.34-pound weight and ultra-compact 2.26 x 3.92 x 0.63-inch dimensions further attest to its mobile superiority.

Engineered to rid noise, distortion, and unnatural coloration from your music, A&norma SR15 comes with first-rate processing power and speedy responsiveness by way of its quad-core CPU. When combined with the CS43198 DACs, the circuitry delivers the kind of liveliness, warmth, detail, clarity, and purity for which high-res audio is renowned. A simple USB connection permits A&norma SR15 to be used as a digital music storage device and/or as a preamplifier to output digital audio through USB. In addition, A&norma SR15 transfers DSD in native format through DoP (DSD over PCM) and converts DSD to PCM for output for external USB audio that does not support DoP.

Of course, such sonic potential in a portable player remains incomplete without an intuitive user interface. A&norma SR15's playback-focused, simple-to-master system comes directly from Astell & Kern's award-winning A&ultima SP1000 model. An onboard rechargeable lithium-polymer battery, 64GB of built-in memory, up to 400GB of external memory via a microSD card, and support for OTA firmware upgrades make A&norma SR15 the antithesis of normal. 100% Music Direct Guaranteed.

A First for Portable Players: Cirrus Logic MasterHIFI-Class Dual CS43198 DACs
