The A&norma SR15 uses two audio DAC chips for a Dual-DAC setup. These chips are known for their use in Home Hi-Fi systems which offer greater presence compared to the inferior DAC chips designed for mobile devices.
There are many devices that use DAC chips for audio processing, however there are different tiers and quality of chips sought by Hi-Fi audio manufacturers to deliver an experience close to the original performance.
A&norma SR15 has adopted the MasterHIFI™ class DAC, CS43198 for the first time in portable system. At Astell&Kern, we believe that true Hi-Fi should sound as close as possible to the original performance. The CS43198 is one of few DAC chipsets that is capable of bringing us even closer to the original when it's matched with the analog amp design of Astell&Kern. In result, it brings even more liveliness and warmth of sound without distortion.
Furthermore, A&norma SR15 supports native DSD bit-to-bit, and gets one step closer to the Hi-Fi system.
The A&norma SR15 plays any resolution of digital files up to 24-bit/192 kHz, bit-for-bit. For 32-bit audio, downsampling is performed by the SRC (Sample Rate Converter) method. DSD is native up to 64 MHz and DSD 128 MHz is converted to PCM for playback.
* 32-bit, 384 kHz is downsampled to 24-bit, 192 kHz, and 32-bit, 352 kHz is downsampled to 24-bit, 176 kHz for playback.* DSD 128 is converted via DSD-to-PCM to PCM 24-bit, 176 kHz for playback.
A simple USB connection will allow the A&norma SR15 to be used as a digital music storage device and or pre-amp to output digital audio through USB. The 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 do not support DoP.
* USB audio (Digital Out) output is available only when an external device can accept digital input through USB.
*DoP (DSD over PCM): This is the standard for transferring DSD data to a USB interface and sends DSD data by mounting them onto PCM data frames.
* The type of OTG cable to connect the SR15 with a portable amp differs depending on the specs of the amp. An OTG cable is not included in the SR15 package.
