    The amplifier operates in the AB-class and is equipped with a linear power supply unit with a massive 400 VA toroidal transformer, which can output 80 watts per channel at 8 ohms and 130 watts at a four-ohm load. In addition to the two linear analog inputs, the amplifier has two optical and two coaxial digital inputs, the latter allowing decoding of the PCM stream from MQA. Digital-to-analog conversion up to 24/192 is implemented on a Burr Brown chip. The aptX Bluetooth wireless connection ensures stable transmission of music content from mobile devices at a distance of up to 15 meters.
