The SR25 is the second model in the Astell&Kern A&norma standard line.
Beginning with the AK70, Astell&Kern's goal was to bring high resolution
audio and the Astell&Kern sound to more music lovers. This goal continued
with the successor to the AK70, the A&norma SR15, and now evolves further as the
SR25, a premium product that fully embraces Astell&Kern's philosophy and
technology, now available to the masses.
The SR25 is the latest answer to
our never-ending question of "How do we get closer to the original sound the
The SR25 improves on the SR15 by: - Adding a new,
faster Quad-Core CPU paired with the Dual Cirrus Logic CS43198 Master Hi-Fi
level DAC, first used on the SR15 - Native playback support for DSD256 - A
new class-leading performance mode for ultra-high quality playback without
compromise - Newly designed circuitry to improve sound quality enhancements
- Addition of Bluetooth LDAC codec to give users more options for higher quality
The essence of Astell&Kern's philosophy that sound quality
is never compromised is exemplified in the SR25, which expresses every musical
detail and bit-perfect playback as only Astell&Kern can.
Performance Mode for Ultra High Resolution Sound The SR25
supports native DSD256 and 32bit/384kHz audio for the first time in an
Astell&Kern standard product and boasts performance that cannot be compared with
other competitors' products.
The SR25, which is smaller than other
players, has been developed to achieve stable, ultra-high resolution sound.
We have developed a new Performance Mode with the SR25 that automatically
optimizes and sets the memory mode in the system according to the data size of
the source being played.
As the resolution of the sound source increases,
it is necessary to process a large amount of data rapidly. If this part is not
optimized, sound breakup may occur. To prevent this, the SR25 uses the new
Performance Mode to adjust and optimize the system in order to produce near
perfect sound quality when playing back high resolution audio.
ultra-high resolution with the SR25's Performance Mode, which reproduces even
the smallest, minute details of the original recording the artist was looking
for, without compromise.
Perfect Circuit Design for the Highest Sound Quality Proper playback of DSD256 and 32bit/384kHz digital audio requires a
high-performance CPU and fast memory speed, along with an audio path suitable
for high-speed signal processing.
Optimizing the length of the audio path is a very important
part, as failing to properly do so can create a time delay between the signals
resulting in sound abnormalities.
With the SR25, the Astell&Kern team
developed a completely different PCB design from the existing SR15 to process
the high speed signals where required, resulting in audio path lengths that are
the same, allowing for super-high resolution sound without any delay.
Furthermore, newly designed audio patterns and power circuits for
distortion-free signal transmission and noise rejection are applied to each
The result is an Ultra Low Noise Filter that allows you
experience Astell&Kern's flawless sound, with Zero Noise, on the SR25.
