Materials 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.
The 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.
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 design 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 analogue 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.
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.
