Get the complete Astell&Kern experience from our most compact, affordable digital audio player yet - it has the power to keep you entertained all day long.
Making the unique Astell&Kern experience available to as wide an audience as possible doesn’t leave room for compromise. So SR25 features native 32-bit/384 kHz and DSD 256 playback, thanks to its outstanding Cirrus Logic CS43198 Master Hi-Fi DAC. This kind of performance is without equivalent at the price.
Despite its usefully compact dimensions, SR25 has the stamina you need for even the longest listening sessions. A playback time of up to 21 hours from a single charge is well within reach, without any compromise to the sound quality that makes Astell&Kern such a discerning choice in the first place.
As well as 24-bit aptX HD Bluetooth wireless playback, SR25 adds support for LDAC wireless connectivity too. Your options are increased - so you can enjoy thrilling high-resolution A&K sound quality using a huge range of wireless headphones and speakers.
Nobody else’s digital audio players perform like ours - and nobody else’s look like ours, either. That’s thanks to our incredible 5-axis machining, which processes solid aluminium billets in one uninterrupted process. So your SR25 looks and feels as good as it sounds.
The SR25 user interface is based on Android 9.0 - and then it’s customised to give a smooth, straightforward experience that’s unique to Astell&Kern. Integrate your favourite streaming services and internet radio stations - and then hear them at their absolute best.
