Astell&Kern has become a beacon in sound quality, utilizing the most advanced technology for their A&ultima series. As the most recent release, the A&ultima SP3000 embodies a decade of research in digital music production.
A&ultima SP3000 is the world’s first DAP with independent Dual Audio Circuitry and the latest DAC with HEXA-Audio Circuitry structure, and uses all audio technologies and the best materials that lets you feel the overwhelming impact of sound and music.
Experience perfection firsthand with the true next-generation flagship, A&ultima SP3000, the pinnacle of audio players.
In pursuit of the A&ultima series' objective of providing unparalleled excellence using cutting-edge design and precise manufacturing, the SP3000 adopted 904L stainless steel, an unprecedented choice for a portable audio player, to elevate it to the level of a luxurious item.
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.
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.
