Description
A Pocket Powerhouse 
True to the core values of Astell&Kern, high fidelity sound lies at the heart of the SR25 MKII, delivering exceptional audio performance to a diverse range of music lovers. The most distinctive feature of the Astell&Kern A&norma product line is its compact form factor. However, the SR25 MKII offers more detailed sound than its predecessor, allowing the clear expression of each and every instrument and vocal note. 

The SR25 MKII offers more versatile connectivity options with the addition of a 4.4mm balanced output for the first time in an A&norma player, LDAC, as well as Qualcomm® aptX™ HD, which support and deliver true audiophile sound quality.
 
The SR25 MKII keeps everything we love about the SR25 and adds new design features. It will produce the best sound quality anywhere, anytime.



Silver Plating Shield Can
Astell&Kern products apply shield cans so that noise and electromagnetic interference, which occur when the countless parts are in operation, do not affect the audio block.The SR25 MKII has taken it a step further by applying highly conductive, hyper-pure silver plating on the existing shield cans for perfect shielding that provides excellent audio performance.
 


Multiple Output Options
The SR25 MKII supports 4.4mm balanced output. With 2.5mm, 3.5mm and 4.4mm output options, you can connect an even wider variety of devices.
The 4.4mm balanced output provides improved dynamic range and bass response, supports a wide soundstage, offers clear imaging, and captures subtle details in the audio source.
Enjoy your music without worrying about adaptors.



ReplayGain Automatically and Uniformly Adjust Playback Volume
ReplayGain, which adjusts sound sources with different volumes to an identical level, has been applied. Now, enjoy your own playlists seamlessly through the ReplayGain feature on SR25 MKII. ReplayGain supports up to 24bit/192 kHz sound sources.



Wireless Hi-Fi Sound Through BT Sink
The newly introduced BT Sink function connects the SR25 MKII to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker.
Music from an external device, such as a smartphone can now be played back in high-quality on the SR25 MKII using the BT Sink function.
