A&Norma SR25 MKII Portable Hi-Fi Music Player with Qualcomm aptX HD

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 supports and deliver true audiophile sound quality.   

The SR25 MKII keeps everything you love about the SR25 and adds new design features. It will produce the best sound quality anywhere, anytime.

Features:

  • The SR25 MKII is a true mass premium product
  • Improved audio quality compared to the SR25
  • Versatile connectivity, with the addition of 4.4mm balanced output support
  • Energy-efficient design resulting in 20 hours of continuous playback
  • Supports two-way Bluetooth and high-definition codecs (Qualcomm® aptX™ HD, LDAC)
  • ReplayGain automatically maintains a constant volume

Multiple Output Options

The SR25 MKII supports a 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.

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.

Excellent Continuous Playback Time

No need to worry about battery life. The SR25 MKII can play continuously for 20 hours with just one full charge, thanks to its optimized, energy-efficient circuitry.

Enjoy your own personal musical performance anytime, anywhere with the SR25 MKII’s extended playback time and its portability.

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.

RelpayGain Automatically and Uniformly Adjusts 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.

AK File Drop to enjoy wireless transfers

The new AK File Drop function in the SR25 MKII makes files transfers easier and more convenient. Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program located on the same network. Music file management is now possible with a cableless, wireless solution.

Design

The A&norma SR25 MKII inherits the overall design identity of the A&norma SR25 model, highlighting the rhythmic freedom of music through the harmonious combination of design elements.

The top and bottom edges of the bezel are angled, giving the impression of a smaller rectangle floating freely inside the chassis. The pattern on the side is designed to draw attention to the volume wheel whilst conveying an impression of sound.


AK CD-Ripper MKII

Perfect Extractor; The Second Story

AK CD-RIPPER MKII, the second model of AK CD-RIPPER, seamlessly delivers CD music to the Astell & Kern player with a single touch. Maintaining previous models' stable performance, the new model supports an enhanced design for more complete ripping. Use your AK CD-RIPPER MKII for smooth, trouble-free ripping of CD music to the Astell & Kern player.

Connections

You can easily connect the AK CD-RIPPER MKII with Astell&Kern music players using the provided cable.

*The AK CD-RIPPER MKII may not be properly recognized when using a power supply adapter rated at less than 5V 2A.

Convenient Ripping

CD ripping is simple and convenient with the AK CD-RIPPER MKII.

By setting up the ripping options in advance, you can connect the AK CD-RIPPER MKII and simply touch the CD ripping icon to begin.

The connected Astell & Kern music player will access Gracenote's servers featuring the latest music data and automatically write the corresponding music information and album cover to the ripped music files. The user also has the option to manually enter metadata such as album title, artist, genre, and year of release for CD information that is not available on Gracenote.

Furthermore, the user can set the ripping speed (normal / fast / very fast) and file format (WAV / FLAC) through the settings menu.

*You can begin ripping CDs after connecting and then activating the AK CD-RIPPER MKII from the Notification Bar.

Design Concept

The AK CD-RIPPER MKII combines distinctively shaped components made of the best materials to ensure critical functions operate at the highest standards of performance.

The main body’s insertion slot for the CD is now a rectangular shape for a more vivid design and has an increased weight to effectively limit vibrations.

The triangular support damper under the body uses a spring structure to manage vibrations resulting from CD rotation so music lovers can enjoy error-free ripping.
