Description
Astell & Kern SE300 Portable Music Player IN STOCK
Titanium (with Case) In Stock.
The new Astell & Kern SE300 is the first A&K player with true analog sound with R2R DAC and Class A and AB amplification.It features two new firsts for an Astell&Kern music player: an R2R DAC and Class A/AB dual amplifiers. The A&futura line of AK music players continues to innovate in new and exciting ways. Bringing new technology and sonic possibilities to your music, the new SE300 is a music player like no other.
The new SE300 combines the DAC and the AMP sections for the first time during an initial design phase. The SE300 comes equipped with an R-2R DAC instead of a Sigma Delta DAC that is most commonly used in other portable music players. The R-2R DAC, also known as a ladder DAC, arranges resistors in a ladder form and offers natural yet dynamic Hi-Fi sounds. It is extremely technical and difficult to execute as it requires complex refined resistor units and hard-to-manage current controls.
Despite these technical challenges and after several years of development and much trial and error, Astell&Kern has managed to overcome this and create a new analog sound. In the process, AK has meticulously selected each of the 96 ultra-precision resistors and finalized the R2R DAC technology. The SE300 takes us one step closer to realizing real analog sound from a digital source, and it’s the result of a long journey taken by Astell&Kern with uncompromising craftsmanship to find the ultimate sound solution.
The SE300 Includes A Case.
