A & SR15 standard defines the Hi-Fi standard for those approaching the audio world for the first time. SR15, the first model of the A & norma series, is the starting point to enter the Hi-Fi Audio world and to discover and enjoy the philosophy and design technology of Astell & Kern, acclaimed by audiophiles around the world. A & norma SR15 uses a double audio DAC The use of the double DAC is much appreciated in the HiFi domestic audio of a certain level, and certainly in terms of performance and quality, it differs considerably compared to those used in "mobile" devices. In the domestic field, however, DACs of different brands are used, each one differentiated by the other for performance, cost and functions. A & SR15 standard employs the MasterHIFI ™ class DAC, Cirrus Logic CS43198, for the first time used in a portable device. The CS43198, for Astell & Kern, is the only DAC currently on the market, to return a faithful reproduction of the music played live, and if properly coupled to an analogue output stage of the same level, has no competitors.
In addition, A & SR15 standard supports bit-to-bit native DSD, which makes it a very high-level and unique Hi-Fi object. 24-bit playback, 192 kHz Bit-to-Bit A & SR15 standard reproduces any digital file up to 24-bit / 192 kHz, bit-to-bit resolution. For 32-bit files, a resampling is performed with the SRC (Sample Rate Converter) method. The 32-bit, 384 kHz files are resampled at 24-bit, 192 kHz, and 32-bit, 352 kHz is resampled at 24-bit, 176 kHz. The native DSD files are played up to 64 MHz and the 128 MHz DSD files are converted into 24-bit, 176 kHz PCM. Audio processing with Quad-core CPU Many think that in a Hi-Fi system only sound is what matters. If in general it is definitely the most important thing, we must take into account that there are other factors that influence the musical experience. A & SR15 standard is designed to remove distracting elements, such as noise and distortion, and present the user with a high-end graphical interface. The Quad-core CPU is able to process audio signals faster and at the same time give immediate access to the user interface.
A & norma SR15 adopts the same latest generation graphical user interface, introduced with the SP1000 model. It has been considered by all as an index of simple and intuitive, as well as being attractive on an aesthetic level. USB Audio A simple USB connection, allows A & SR15 standard to be used as hard disk storage of digital music and / or preamplifier with digital output via USB. A & SR15 standard transfers native DSD files in the DoP format (DSD over PCM) and converts DSD files to PCM to send them to the USB output that does not support the DoP format.
