Additional detail and balance
Although it has a familiar look and feel, this new pocket powerhouse delivers greater sound thanks to Astell&Kern’s newest advanced audio design technology.
The natural high-resolution sonics produce clearly defined upper and lower tones as well as a deeper, more rounded sound than its predecessor.
The addition of the balanced 4.4mm headphone connector, which joins the 2.5mm (balanced) and 3.5mm (unbalanced) outputs, expands the range of headphones, IEMs, and devices that may be connected.
The 4.4mm balanced output enhances dynamic range and bass response, as well as supporting a larger soundstage and capturing clear imaging and delicate nuances in the audio source.
The SR25 MII, like the first-generation model, supports a wide range of high-resolution music formats and sample rates. Native DSD256 and 32-bit/384KHz PCM high-resolution audio playback brings every music fan closer to experiencing the artist’s original studio sound.
The SR25 MKII includes the latest high-definition Bluetooth wireless codecs: LDAC and aptXTM HD, allowing you to listen to your favorite hi-res music over a wireless connection.
Gain from a replay
In addition, the SR25 MKII adds Replay Gain to the mix.
This adjusts the volume of sound sources up to 24-bit/192 kHz automatically and consistently, allowing playlists to be enjoyed without having to alter the volume.
Additional options for connecting
AK File Drop, which was first launched in the A&futura SE180 player, allows for faster wireless file transfers.
To make music management more easier, users can wirelessly upload files from a PC, smartphone, or FTP software on the same network.
Second, the new BT Sink function allows the SR25 MKII to connect through Bluetooth to an external device, such as a smartphone, allowing high-quality music to be played back on the Astell&Kern player.
Improved internal protection
When internal components are in use, Astell&Kern players employ shield cans to avoid electromagnetic interference.
The SR25MKII has taken additional measures by putting highly conductive, hyper-pure silver plating to the existing shield cans for extra protection against these sound performance-affecting disturbances, which was first introduced in the higher-end A&ultima SP2000T.
The SR25 MKII retains the original SR25’s overall design identity, including the slanted top and bottom bezel edges that give the sense that the smaller inner rectangle is floating freely from the main body.
The new side volume wheel design is more distinct and tactile, calling more attention to this area of the player.
Finally, the new deeper silver (Mercury D. Silver) distinguishes itself from the Moon Silver livery of the original.
Keep an eye on your A&K player
To complement the SR25 MKII, a protective case in a choice of three eye-catching finishes is available to protect this premium player from the rigors of life on the road.
This memory material is made from a soft and durable LASKINA® polyurethane fabric from Italy, and it provides exceptional grip while protecting against external shocks and scratches.
The fabric also has the texture of traditional, high-end leather, with natural leather-style creases and sheen, creating a sumptuous and bright appeal.
Denim Blue, Orange, and Black are among the available colors.
