DAPs

From Astell&Kern

The SE200 is the second model from the Astell&Kern A&futura premium line of Digital Audio Players.

After the first model SE100, we were once again thinking about the nature of the word premium and asked ourselves, "What is the value of premium in Hi-Fi and how can we express it with a product?" We decided to "Let's make One device that nobody can duplicate" We wanted to try something no one else has tried before, including Astell&Kern. The result is the SE200.

• Equipped with the world's first Multi DAC (1x AK4499EQ + 2x ES9068AS)
• Independent AMP structure designed to compliment each DAC's characteristics and DAC Filters to create your own sound
• Audio performance to feel premium Hi-Fi sound presented by Astell&Kern
• Upgrades that add a Premium value experience

World's First Multi-DAC DAP

The A&futura SE200 is the world's first Multi DAC player. Since the release of the Dual DAC AK120 player in 2013, we have not seen any products feature more than Dual DACs in the last seven years. This prompted us to ask the question, "Why hasn't there been more than two DACs in a player?" So, we set out to become the first manufacturer to use more than two DACs and the result is the SE200.

The SE200 features the latest audiophile DACs from ESS, the ES9068AS in a Dual DAC configuration. We then added a single AK4499EQ, AKM's flagship DAC that is used in our flagship SP2000. Combining the three DACs, we have produced the world's first multi-DAC DAP.

This pairing exhibits the philosophy of the A&futura line to pursue fundamentally different sound than found in typical DAPs. To properly implement multiple DACs, we needed to spend twice the amount of time on development and double the amount of time in properly tuning the player.

Astell&Kern is not content to keeping things the same all the time. We are constantly working to improve on what we have already achieved to bring the most accurately reproduced and best sound to our products.

Independent AMP Sections Designed to Match DAC Characteristics

The SE200 was not designed with one AMP circuit, but multiple, different AMP designs to optimize the different characteristics of the AKM and ESS DACs that are used in the player. By separating the signals for each channel of Balanced and Unbalanced, we designed independent circuits that do not interfere with each other to provide the best sound possible.

Your own sound style

The SE200 goes beyond selecting the best DAC for type of music you are listening to. You can now further customize your sound by choosing from a variety of DAC filters provided by the DAC manufacturer. With the SE200, you can now choose your own preferred sound profile.

A premium player line evolved

Every time we create a new Astell&Kern product, we push ourselves to create an even better version than before. The SE200 builds upon the specs that made the SE100 a popular premium product, while offering new features not found in previous players.

Performance Mode for Ultra High Resolution Sound

The SR25 supports native DSD256 and 32bit/384kHz audio for the first time in an Astell&Kern standard product and boasts performance that cannot be compared with other competitors' products.

The SR25, which is smaller than other players, has been developed to achieve stable, ultra-high resolution sound. We have developed a new Performance Mode with the SR25 that automatically optimizes and sets the memory mode in the system according to the data size of the source being played.

As the resolution of the sound source increases, it is necessary to process a large amount of data rapidly. If this part is not optimized, sound breakup may occur. To prevent this, the SR25 uses the new Performance Mode to adjust and optimize the system in order to produce near perfect sound quality when playing back high resolution audio.

Experience ultra-high resolution with the SR25's Performance Mode, which reproduces even the smallest, minute details of the original recording the artist was looking for, without compromise.

Perfect Circuit Design for the Highest Sound Quality

Proper playback of DSD256 and 32bit/384kHz digital audio requires a high-performance CPU and fast memory speed, along with an audio path suitable for high-speed signal processing.

Optimizing the length of the audio path is a very important part, as failing to properly do so can create a time delay between the signals resulting in sound abnormalities.

With the SR25, the Astell&Kern team developed a completely different PCB design from the existing SR15 to process the high speed signals where required, resulting in audio path lengths that are the same, allowing for super-high resolution sound without any delay.
Furthermore, newly designed audio patterns and power circuits for distortion-free signal transmission and noise rejection are applied to each channel.

The result is an Ultra Low Noise Filter that allows you experience Astell&Kern's flawless sound, with Zero Noise, on the SR25.

Embark on a Musical Journey That Lasts the Entire Day

If the power supply's stable design and efficiency are not properly taken into consideration, the input/output voltage difference becomes large, and when the output current is large, the output voltage can become unstable. This leads to excessive noise being generated, which can be a major cause of poor sound quality. In addition, poor power efficiency will result in a shorter playback time.

The SR25 set a big challenge for the Astell&Kern engineering team – add the longest playback time of any previous Astell&Kern product, while maintaining the signature Astell&Kern quality sound, and a low-noise floor.
In the SR25, the team not only applied highly efficient components, but they focused on developing circuit optimizations to get the most out of their performance.
The result is up to 21 hours of continuous play time, more than double the previous generation SR15, with no compromise in sound quality.

No need to worry about battery life while on your daily journey, just have fun on your Music Trip with the SR25.

Continuous Playback Time

* Standard - MUSIC: FLAC, 16-bit/44.1kHz, Unbalance, Volume 80, EQ OFF, LCD OFF

No Compromise on Sound, Even When Connected Wirelessly

In addition to 24-bit music playback via aptX^TM HD Bluetooth as in previous Astell&Kern players, the SR25 adds LDAC support to give users more options to listen to high resolution audio wirelessly.

Now you can enjoy Astell&Kern's high-quality sound when paired to Bluetooth earphones, headphones and speakers.

Astell&Kern's Exclusive Metalworking Technology

Astell&Kern products are often compared to art sculptures, with colorful faces and angles not found in other products. This precise design work is based on Astell&Kern's long accumulated know-how and highly precise metalworking technology.

In order to produce this unique style Astell&Kern is famous for, 5-axis machining is performed instead of traditional 3-axis machining used in general machining. All metal must be processed at once without interruption.
In addition to 5-axis machining, Astell&Kern has perfected it's crafting of metal through thousands of hours of trial and error. Only after mastering these techniques that Astell&Kern has developed, can the beauty of the metal shine through.

The vibration-free processing machines used by Astell&Kern are the same ones used by expensive Swiss luxury watch manufacturers. This is reflected in the crafting of the volume wheel which is processed precisely like the crown of a luxury watch for the best operating feel.
Astell&Kern products are designed to achieve perfect integration at whatever angle you look at it in your hands.

The Aluminum body on the SR25 provides maximum sound quality, while suppressing noise as much as possible. The use of laser ground extension technology gives you the best sound possible, without interference or distortion.

Astell&Kern combines these small parts to make a big difference in the quality of our products that no other manufacturer can match.
