Desciption

Fully Discrete 24bit R-2R DAC

To ensure the A &futura SE300 audio player better reproduces analog
sounds, we set out to combine the DAC and AMP sections for the first time
during the initial design phase.

The SE300 comes supplied with an R-2R DAC, instead of a Delta-Sigma DAC
that is most commonly used in other audio players. R-2R DAC, also known as
Ladder DAC, as it arranges resistors in a ladder form, offers natural yet
dynamic Hi-Fi sounds, but it is extremely technical and difficult to execute
as it requires complex refined resistor units and hard to manage current
controls. However, despite these technical challenges, after several years for
development and a lot of trial and error we have managed to overcome this and
create a new analog sound. In the process, we have meticulously selected each
and every one of the 96 ultra-precision resistors and finalized our R-2R DAC
technology.

SE300 takes us one step closer to realizing analog sound from a digital
source and is the result of a long journey taken by Astell &Kern with
uncompromising craftsmanship to find the ultimate sound solution.

Realization of 24-bit Decoding with R-2R DAC

The R-2R DAC within the SE300 arranges 48 pairs (23xR and 25x2R) of 96
ultra-precision resistors to create analog signals, in turn realizing true Hi-
Fi 24-bit decoding.
