Owing to its understated style and groundbreaking functionalities, the SP4000 offers an A-grade listening experience. We will explain the main features of this amazing equipment above.
Astell&Kern A&ultima SP4000 Hi-Res Digital Audio Player
SP4000 is a masterpiece in terms of sound quality. Its sound is pure, and very minute details can also be heard throughout the entire range of the sound. The player is fitted with two AKM AK4499EX DAC chips for that purpose. It supports High-resolution playback up to 32-bit/768 kHz PCM and native DSD512. This is really the ultimate sound experience for cinephiles.
Unrivalled Sound Quality
The SP4000’s power supply features a New Low-Dropout (LDO) Regulator. This change leads to a significant noise reduction of approximately 97% compared to the older models. To put it briefly, LDO Regulators are top-of-the-line parts necessary, among other things, in the precision medical field and 5G communication. They not only stabilise the battery voltage but also quite efficiently attenuate noise.
Luxury and Durability
This digital audio player is perfect in both function and form. Apart from being a top product of stainless steel, the body also radiates elegance of durability and resistance to wear and tear. The 5.5-inch Full HD touchscreen improves the attractiveness of the design while maintaining its modernity and functionality. The SP4000 is truly the perfect blend of style and sound.
First-Ever Implementation of Advanced DAR by Astell&Kern
The SP4000 is the first product to bring in the Advanced DAR, the sound remastering technology from Astell&Kern. The new generation surpasses the previous artist’s idea of the natural sound. Instead of passing the music file straight to the DAR unit, the SP4000 employs VSE (Virtual Sound Extender) first to bring back the lost harmonics due to compression.
Thereby, in essence, upgrading the sound quality at the source stage. The advanced DAR unit performs the second-stage upsampling with even more accuracy and completeness. As a result of this two-step process, the fans can access a much richer and more engaging sound close to the original recording.
Latest Snapdragon Octa-Core CPU Flagship Device
The <ima SP4000 has been designed with a Snapdragon 6125 Octa-core processor. So you can get an incomparable sound that goes on to faster system response and a new generation user interface, which changes smoothly and comfortably. With a high-performance CPU with 8GB of DDR4, the memory has doubled compared to the commonly used one.
Thus, increasing the power of the more stable system gives faster and fluid movement. The CPU, memory, and wireless communication parts are assembled as one unit. The digital circuit parts are positioned in the same area. Thus, a single system on a chip (SoC) is formed.
As a result, this facilitates the overall circuit configuration to be efficient. Thereby providing more space for the audio-only circuit and less heat and noise from digital circuits.
Enhanced User Experience
The SP4000 cares not only about sounds but also about the user experience. Thanks to reinforcement in the interface and software, music library navigation is very simple and natural.
The addition of Wi-Fi and Bluetooth has made streaming and music management way more comfortable. Finally, its big storage and the fact that a flexible memory card can further extend it mean that it is possible to have all the tracks you want in one place.
