Equipped with stunning engineering and topped off by the extraordinary construction quality that characterizes Astell&Ken's creations, the A&futura SE300 shines especially for the refined and groundbreaking D/A conversion scheme that it incorporates, type R-2R (ladder resistors) and which gives its sound a genuinely “analog” warmth with respect to the restoration of the Delta-Sigma type “chips” used by the vast majority of digital sources.
The TERATON ALPHA technology of the Asian company contributes powerfully to this, without which the aforementioned addition would not have been possible, since its contributions include the virtual suppression of the noise present in the power signal, a very efficient management of the latter and immaculate amplification.
Another fundamental element of the new Astell&Kern is the innovative Dual AMP mode, which allows the user to select between Class A and Class AB amplification, which results in, respectively, sound naturalness and dynamics.
