Styled in dark gray, the Astell&Kern A&norma SR15 aims to be a portable system for playback of high-res audio, utilizing dual Cirrus Logic CS43198 chips and supporting 24-bit/192 kHz bit-to-bit type playback. The 64GB of on-board storage can be expanded with a microSD card (up to 400GB, total). The device can also work as a preamp for digital audio over USB.
32-bit audio is down-sampled using a sample-rate converter, and DSD 64/128 can be played back through conversion to PCM. DSDNative, on the other hand, stays in the DSD world. The player sports 3.5mm, 3-pole unbalanced and 2.5mm, 4-pole balanced headphone jacks. The balanced output can remove noise (common mode noise) that can occur in signal and inverting amplifier signal, while offering increased power output due to its double transmitting of signals.
