Description

The New Hi-Fi Standard, A&norma SR25

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 artist intended?"
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 wireless sound

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.


 

Up to 21hrs of Playback

The SR25 set a big challenge for theAstell&Kern engineering team add the longest playback time of any previousAstell&Kern product, while maintaining the signature Astell&Kernquality sound, and a low noise floor. In the SR25, the team not only appliedhighly efficient components, but they focused on developing circuitoptimizations to get the most out of their performance. The result is up to 21hours of continuous play time, more than double the previous generation SR15,with no compromise in sound quality. No need to worry about battery life whileon your daily journey, just have fun on your Music Trip with the SR25.

 


 

The new design of A&norma SR25

A&norma SR25 incorporates drasticchanges without losing the balance between an optimal user experience, looksand keeping the A&norma design identity. The harmonious combination ofthese various design aspects symbolize the rhythmic feel and freedom ofmusic.The player features layers of various sized rectangular surfaces withadded angles to invoke the sense of pulsating musical rhythm from its designPrecisely milled cuts resemble various reflection s of light and create a depthof space around the volume wheel that further emphasizes the bold lightreflections that are created at different angles of view on the entire player.On the back, the bold oblique cut surface of the rear glass meets thetriangular shapes that surround the volume wheel. The patterns of the rearglass beautifully express the spreading of light when it is reflected off thesurface. The rhythmic pattern on the rear glass will change as light isreflected at different angles.The new SR25 is ideal for one handed operationand is a perfect fit no matter which hand you choose to hold it in . The angleof the front screen and extra space around it gives you the perfect grip whenit’s held.

 


 

Astell&Kern's Exclusive MetalworkingTechnology

Astell&Kern products are often comparedto art sculptures, with colorful faces and angles not found in other products.This precise design work is based on Astell&Kern’s long accumulated knowhow and highly precise metalworking technology. In order to produce this uniquestyle Astell&Kern is famous for, 5-axis machining is performed instead oftraditional 3-axis machining used in general machining. All metal must beprocessed at once without interruption. In addition to 5-axis machining,Astell&Kern has perfected it’s crafting of metal through thousands of hoursof trial and error. Only after mastering these techniques that Astell&Kernhas developed, can the beauty of the metal shine through.

 


 

Swiss luxury watch craftsmanship of thevolume wheel

The vibration free processing machine sused by Astell&Kern are the same ones used by expensive Swiss luxury watchmanufacturers. This is reflected in the crafting of the volume wheel which isprocessed precisely like the crown of a luxury watch for the best operatingfeel.

 


 

Perfect Circuit Design for the HighestSound Quality

Proper playback of DSD256 and 32bit/384kHzdigital audio requires a high performance CPU and fast memory speed, along withan audio path suitable for high speed signal processing. Optimizing the lengthof the audio path is a very important part, as failing to properly do so cancreate a time delay between the signals resulting in sound abnormalities. Withthe SR25, the Astell&Kern team developed a completely different PCB designfrom the existing SR15 to process the high speed signals where required,resulting in audio path lengths that are the same, allowing for super highresolution sound without any delay. Furthermore, newly designed audio patternsand power circuits for distortion free signal transmission and noise rejectionare applied to each channel. The result is an Ultra Low Noise Filter thatallows you experience Astell&Kern's flawless sound, with Zero Noise, on theSR25.

 


 

No Compromise on Sound, Even When ConnectedWirelessly

In addition to 24bit music playback viaaptX HD Bluetooth as in previous Astell&Kern players, the SR25 adds LDACsupport to give users more options to listen to high resolution audiowirelessly. Now you can enjoy Astell&Kern's high quality sound when pairedto Bluetooth earphones, headphones and speakers.
