Improving on a personal best
The original SR25 was a multi-award winner that took the market by storm. The Astell & Kern SR25 MKII offers improvements all round, making the best even better. Using A&K’s latest audio architecture, the MKII sounds more detailed. Other changes include a new 4.4mm headphone socket, Replay Gain function, AK File Drop and enhanced shielding. A new volume control and Mercury Dark Silver finish set the tone.
New, 4.4mm balanced output
New to the SR25 MKII is a top quality, 4.4mm, 5-pole balanced output. Alongside the 2.5mm, 4-pole balanced output, this gives wide-ranging compatibility with both headphones and headphone amps. Using a balanced signal between the source and headphones reduces noise and interference and is especially handy on the move. A standard 3.5mm unbalanced socket is also standard.
Quad Core and Dual DACs
Featuring a Quad-Core CPU, the SR25 MKII has the power to get the most from your Hi-Res music files. Hi-Fi quality, Cirrus Logic CS43198 DACs (Digital to Analogue Convertors) provide the SR25 MKII with exceptional resolution. Meeting the highest standards for sonic precision, the DACs guarantee a reference level of sound. Using one DAC for the left channel and another for the right, the SR25 MKII offers channel precision and stereo imaging that's well beyond most rivals.
Flexible format player
There are many HD Audio recordings already available to download online and you may already have started a collection on your computer or NAS drive. Where the SR25 MK II really scores is being able to take those recordings with you - in the highest quality possible. The SR25 supports a wide range of file formats, including WAV, FLAC, WMA, MP3, OGG, APE, AAC, ALAC, AIFF, DFF, DSF and MQA.
Native DSD256 support
With native DSD support at DSD256, the SR25 MK II makes the most of this hi-res format. As an alternative to PCM sampling, many of the large music labels, including Sony, support DSD files. DSD is renowned for its huge dynamic range, ‘inky’ quiet backdrop and subtle detail that gives music ‘life’ and realism.
ReplayGain automatically adjusts all the sound sources to an identical level. This lets you listen to a variety of playlists, seamlessly and without distracting jumps in volume.
Connect to your wireless headphones with Bluetooth LDAC
Bluetooth LDAC enhances the quality of a Bluetooth connection for more detailed and dynamic sound. Pair with compatible headphones, such as Sony LDAC models, and enjoy a much more detailed sound than standard Bluetooth connectivity.
AK File Drop for wireless transfer
With the new AK File Drop function, transferring files is easier than ever. The File Drop system lets you freely transfer files wirelessly through a PC, smartphone or FTP programme located on the same network.
BT sink for wireless music transfer
With the new BT sink function, you can now wirelessly stream music to the SR25 MKII, similar to the way the player streams to your wireless headphones or Bluetooth speaker. Simply pair with your music device, such as a smartphone, tablet or laptop and stream the music across – wirelessly.
Long-lasting battery life
With a battery life of around 20 hours, the SR25 MK II has the power to keep going for the longest journeys. Charging time is around 2.5 hours.
Store it all - 64GB internal memory and now with support for a massive 1TB
With 64GB of internal memory, the SR25 MKII stores about 625 tracks (24 bit/96kHz, 4 minute-long, 90MB) songs on its flash memory. With the addition of a micro SD card, this can be increased by up to a massive 1TB – enough for a lifetime’s collection of music.
Enjoy music from the best Hi-res player in its class, with the Astell & Kern SR25 MKII.

Rated 5 out of 5 by Smith09 from Premium sound and quality Had this a month now and it's worth every penny. A real step up in sound quality from a smartphone.

Rated 5 out of 5 by Thing50 from Exceptional detail I never thought I would once again be hearing detail in my music I had not heard before but A&K have excelled themselves with this player…an improvement over the original SR25 which I owned previously, better soundstage and detail definently…I listen to my personal collection of FLACs on this player I do not use a streaming service, just to note this review is based on that kind of usage.

Rated 5 out of 5 by MMax from Exceptional Service I bought an Astell & Kern SR25 last May. A really nice piece of kit but - I discovered one morning that the back had partly separated from the rest of the unit. (We still don't know why.) The staff at Richer Sounds Leicester dealt with this very efficiently and arranged for A & K to replace it with a Mk2 model. So, I now have an even better player and can recommend both the player and Richer Sounds. Well done everyone.

Rated 5 out of 5 by craig 99 from Astell and kern sr25 mk 2 I purchased the Astell and kern mk2 and I could not be happier with it the soundstage is top class way better than a phone or a iPad. I would like to say a special thank you to the staff at Eton richer sounds who are very knowledgeable and very professional and I would recommend them if you need any electrical purchases just pick up the phone and give them a call .
