As an interesting feature, the Astell&Kern A&Futura SE180 music player offers the option of changing DAC modules. For example, with the new SEM4.
DAC’s often sound different, and therefore being able to choose between ones is sometimes quite handy. This is also what Astell&Kern has figured out. And so their mobile music player A&Futura SE180 offers the possibility to swap DAC modules. Here, the new SEM4 comes in quite handy. This module offers among other interesting stuff Digital Audio Remaster (DAR) upsampling technology, which should improve the source’s samplerate. As a base, the SEM4 uses the Asahi Kasei AK4493SEQ dual DAC. The optional module has a price tag of €1599 and is available per direct.
