Descrizione generale
Astell&Kern A&ultima SP4000 è il lettore audio digitale di punta della serie A&ultima, progettato per offrire un'esperienza sonora senza compromessi.

Il sistema operativo Android completo, la tecnologia DAR avanzata e il processore Snapdragon octa-core garantiscono prestazioni elevate sia in termini di qualità audio che di usabilità. Il design in acciaio inox 904L e la custodia in pelle di vitello tedesca confermano la vocazione luxury del prodotto, mentre le tecnologie proprietarie come ESA, High Driving Mode e ADP assicurano una riproduzione musicale precisa, potente e coinvolgente.

About Astell&Kern

Astell&Kern: DAP and audio player to experience liquid music at its best

The goals of Astell&Kern are certainly ambitious: to offer products capable of touching people's hearts and bringing joy. A real mission that is expressed in the offering of DAP digital players, DAC modules, headphone amplifiers, Bluetooth receivers and much more.

Modern devices designed to listen to liquid music to the fullest and experience your content as you see fit. This, then, seems to be exactly the meaning of the Korean manufacturer's product range, which has been on the market since 2013 and is already able to establish itself as a serious and credible reference in the field of high fidelity.

SP2000T, SR25, CA1000: the great successes of Astell & Kern

There are many successful products included in the range of the Asian brand. Among the most popular is undoubtedly the Astell & Kern SP200T, a high-resolution DAP digital player capable of handling various formats at 32bit/384kHz. The same approach is followed in another of the company's flagship devices, namely the SR25 music player, capable of running native DSD files at 11.2MHz.

The company's catalog evidently is not limited only to portable devices for high-definition music playback. Headphone listening also has its importance, demonstrated by Astell&Kern ACRO CA1000, an amplifier with ESS ES9068AS DAC designed for high-impedance devices.

Leaving aside the individual products, in any case, what is surprising is the variety of proposals dedicated to liquid music and beyond. Between DAPs, headphones, home audio solutions, and accessories (such as remote controls and receivers), the choice is truly vast.

Devices to appreciate the endless possibilities of liquid music

"We believe our products touch people's hearts, not just their ears." On the official website of the Asian brand it is possible to read such phrases. A real declaration of love for the audience of enthusiasts and audiophiles, and for all those who demand audio devices capable of uncompromising performance.

The whole approach given to the brand, in any case, suggests an idea of high quality and attention to detail. Just think that the company's name comes from the union of "Astell" (star in Greek) and "Kern" (core in German). Five-star devices capable of excitement, then, of getting straight to the listeners' hearts, of hitting the target of offering quality listening.

An approach taken up by all the company's thickest lines, from A&ultima to A&futura, via A&norma. Products that make it possible to listen to and play music in a highly personal way. Digital music, often defined as cold and impersonal, thanks to Astell&Kern finally becomes rich in emotion.
