Equipped with a stunning engineering and topped by the extraordinary constructive quality that characterises Astell&Ken's achievements, the A&futura SE300 shines especially for the refined and groundbreaking D/A conversion scheme it incorporates, of the R-2R (ladder resistors) type, which provides its sound with a genuinely "analogue" warmth with respect to the restitution typical of the Delta-Sigma chips used by the vast majority of digital sources.
The Asian company's TERATON ALPHA technology is a major contributor to this, without which this addition would not have been possible, as its contributions include the virtual suppression of noise in the power supply signal, very efficient power supply management and immaculate amplification.
Another key 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 with the resulting natural sound and dynamics.
