Material Innovations, World’s First Use of Stainless Steel 904L for DAP Body Material

To achieve the goal of the A&ultima series, which is 'to provide the best value that no one can imitate while using the most innovative and uncompromising design and craftsmanship', the SP3000 uses 904L stainless steel material that has never been attempted before in a portable audio player. Using this material has expanded its value from just a digital device to the realm of a luxury good.

904L stainless steel is harder and more difficult to process than general stainless steel requiring significantly more time and effort. However, due to its excellent durability and corrosion resistance, it has a characteristic that does not lose its beauty and is why it is used in expensive luxury watches where perfection in all materials and parts must be pursued with an irreplaceable and wonderful luster.

Experience the uncompromising beauty and luxury of the SP3000 produced by Astell&Kern’s experienced craftsmanship.

 

TERATON ALPHA: The Essence of A&K Audio Technologies Merged Into the SP3000

In order to develop the ultimate audio player that has never been experienced before, not only do we use the latest DAC and technology available, but we use the innovative audio technology of TERATON ALPHA, AK's Ultimate Sound Solution, which has been refined for the SP3000.

TERATON ALPHA, engineered through endless research, is Astell&Kern's unique technology that has been designed to produce audio playback that is close to the original sound through effective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface. HEXA-Audio Circuitry structure and independent dual audio circuit, implemented for the first time in the SP3000, are paired together with TERATON ALPHA's sound solution to create the purest original sound.

 

First Use of AKM’s Latest Flagship DAC, Complete Separation of Digital and Analog Signals

The SP3000 is a flagship product with the latest technology and uncompromising design. Astell&Kern worked with AKM from the initial development stage to develop the DAC and circuit structure.

As a result of the collaboration, the world's first four AK4499EX DACs, AKM's latest flagship, were applied to the SP3000, and the innovative HEXA-Audio Circuitry structure in which two AK4191EQs that process digital signals are applied separately, complete the amazing sound that can only be found from Astell&Kern.

Most digital players process digital and analog signals together inside the DAC. However, the SP3000’s advanced HEXA-Audio Circuitry structure reduces the noise of the digital signal input through the AK4191EQ, a separate digital delta-sigma modulator, and the AK4499EX DAC is then designed to process the analog signals separately. By applying this unique design, digital and analog signal processing that is physically separated has been achieved for the first time in a digital audio player, and the overwhelming SNR (Signal-to-Noise Ratio) is maximized, making it possible to experience an incredible level of sound that has never been experienced before.

 

Silver Plated Shield Can

A shield can is applied to prevent various noise and electromagnetic interference from affecting the audio block. The SP3000 takes it a step further to achieve excellent audio performance and perfect shielding by applying highly conductive, high-purity silver on the existing shield can, and physically separating digital and analog signals.

 

Stunning Audio Performance with Independent Dual Audio Circuit

In order to create a truly innovative DAP, not just a great DAP, we tried to overcome the limitations of sound by envisioning an independent dual audio circuit that has never been attempted by anyone with a HEXA-Audio Circuitry structure with unbalanced and balanced outputs.

Almost all other DAPs, including Astell&Kern, use an internal DAC for both unbalanced and balanced outputs. Since the signal from the DAC is divided into unbalanced and balanced then delivered to the AMP, an Audio Switch is essential. However, when using a switch, there is a limit to the range that can receive the signal sent by the DAC, so most DAPs reduce the signal size first and then when the signal is transmitted back to the amplifier, it is necessary to restore the original signal size. This causes a limitation in improving the audio performance.

To overcome the limitations, our engineers designed a HEXA-Audio Circuitry structure using two AK4191EQs and four AK4499EXs, creating an innovative unbalanced and balanced independent dual audio circuit design. In result, the SP3000 achieves a SNR of 130dB, the best of any DAP available. You can feel the clean, pure delicacy of sound with the SP3000 that you cannot not experience in any other DAP.

Drive Your Music, Latest Snapdragon Octa-Core CPU for the Newest Flagship Device

A&ultima SP3000 is equipped with a Snapdragon 6125 Octa-core processor, so you can enjoy the overwhelming sound, faster system response and a redesigned generation user interface that moves comfortably and smoothly.

Featuring a high-performance CPU and improved 8GB of DDR4 memory, which is twice the amount commonly used, the more powerful system is stable with fast and fluid movement.

The CPU, memory and wireless communication parts are configured as one module, with the digital circuit parts arranged in the same area creating a single system on a chip (SoC). This maximizes the efficiency of the overall circuit configuration by providing more audio-only circuit space as well as reducing heat and noise from digital circuits.

Heighten Your Music: New Experience in the Graphic User Interface

With the newly developed UX/UI, the SP3000 is focused on the process and experience of listening to music,
and we wanted to become a ‘Player for music’ that one can feel this process.

The new theme is designed with a focus on the experience of rediscovering songs that you have forgotten; you can quickly browse through music categories with simple gestures. A convenient search feature along with album art has been added so that you can enjoy a digital display of CD album covers of your music collection.
It is designed to give you not only the pleasure of listening to music, but also to create fun when operating the device.

In addition, the Crimson theme, one of the main features of the new generation UI, is designed so that you can feel the appearance of the SP3000 on the screen.
The graphics are simple and unintrusive, focusing on usability and intuitiveness. Three key concepts, Edge, Simple, and Dark Mode, were used to improve usability and increase clarity with a style unique to AK. The black and red theme colors are chosen to reduce eye fatigue, maximize battery usage and reduce heat generation.

Sound Design With DAC Filters

With the SP3000, you can have fun creating your own sound style by selecting various DAC filters provided by the DAC manufacturer.

Design your own sound with 6 different DAC filters.

Digital Audio Remaster Technology for Even More Vivid Original Sound

The SP3000 is equipped with Digital Audio Remaster(DAR) technology, which was developed to deliver fine sound at higher sample rates.
DAR technology is developed to upsample the sample rate of the sound source being played to go beyond the limits of the source format.
The high sample rate allows more refined play and offers delicate and analog-like original sound, helping you to enjoy the richness of the original sound, subtle differences in the nuance of the music and rich sounds at a higher level.

Crossfeed: Speaker effect when listening through headphones

In a headphone environment in which the left and right channels are clearly separated, ear fatigue may increase during prolonged listening. The moment you turn on Crossfeed, the experience of crisp, but comfortable sound begins.

Crossfeed mixes parts of the original signal from one channel and sends that signal to the opposite channel with a time difference to center the sound image.

Through the use of detailed settings such as Shelf Cutoff, Shelf Gain, and Mixer Level,
you can set the level of crossfeed according to your listening preferences.

Premium Goat Leather Case

The SP3000 comes with a French goatskin leather case to protect and highlight the beauty of the 904L stainless steel body.

The case is made by ALRAN, located in Tarn in southern France, a historical tannery that was established in 1903 and has been manufacturing leather for over 100 years. It is one of the world’s leading tanneries, well-known for their natural leather manufacturing technology since the 1980’s. ALRAN is recognized as the best goatskin manufacturer and supplies other leading luxury brands such as H and L.

The leather case included with the SP3000 is developed with ALRAN Tannery's unique Hand-Boarding technology. This is a technology that processes the leather by rubbing it in various directions using wooden planks, so you can feel the texture of the surface. This process is unique compared to how other goatskin cases are produced.

Design

The interpretation of light and shadow shown in the SP3000 is expressed as “wrapped in light” whereas the previous SP1000 and SP2000 expressed light as spreading and scattering. The concept of the SP3000 depicts how light gathers and wraps around the wheel.

This symbolizes that the SP3000 is the all-consuming culmination of all the technologies and capabilities that Astell&Kern has accumulated over the years. The polished stainless-steel body shines every moment, and the beautifully shimmering LED light and sharply machined ceramic panel further emphasize the luxury.

The SP3000, which was created through thoughtful design and processing, offers the ultimate in beauty that matches the ultimate sound.

About Astell&Kern

Astell&Kern is the ultimate digital music source that brings you Mastering Quality Sound or MQS. Astell means ‘Stars’ in Latin and Kern means ‘Center’ in German. We believe Astell&Kern is the center of music.

Today, original music performances can be captured in digital almost exactly as they were performed due to new, advanced recording technology currently available. However, these high quality recordings are mainly listened to through inferior sound formats, such as MP3 or through streaming services. With the debut of the MP3 format, music lovers sacrificed sound quality for the convenience of being able to carry their music collection wherever they went. Because the MP3 format heavily compresses files for the sake of convenience, the vocals and instruments you hear are only an inferior version of the original. The soundstage and the ambience of the original performance often disappears when listening to compressed MP3 music. After pondering these issues, Astell&Kern was our solution to poor sound quality for the sake of portability, and our way in reviving the original sound quality of music, MQS, for music artists, recording engineers, and professionals.

Astell&Kern's pursuit is to provide natural and original sound without distortion. It showcases the presence of the original recording with miniscule details you may not have noticed from other music systems, while playing back high-resolution music bit by bit, exactly as it was recorded. The ability to play back the exact recording of any live performance is what Astell&Kern is known for.

The power of true sound from Astell&Kern can now be experienced and has been part of many famous audio exhibitions around the world. Astell&Kern is now admired by music lovers from many countries, including the USA, China, Japan, UK, France, and many more around the world.
