The power amplifier uses a class AB output stage based on four hand matched pairs of mosfet power transistors per amplifier board. Mosfet transistors advantages are numerous compared to usual bipolar transistors. Lower ‘ON’ resistance and the way that the power is identically distributed between the transistors makes them more efficient to transmit more power to the load rather than dissipating it as useless heat. Mosfet technology also has higher switching speed resulting in a faster, sharper and more accurate response compared to bipolar systems. The output stage is biased with a precise voltage to set the operating point of the power transistors to get extremely low THD and exceptional audio performances (THD of 0.01% for 200W on a 8Ω load in stereo and bi-amp mode). Thermal compensation of the output stage has been also developed in order to avoid overheating the transistors when they are strongly solicited. Several internal protections are constantly monitoring the instantaneous power consumption, power supplies voltages and currents and heat sink temperatures of the amplifier.

The two low-noise power transformers are able to provide a total amount of power of 2000VA to the amplifier when used in mono mode. The total capacitance of the power supplies in mono mode is more than 180mF. The oversized power supplies guarantees the unit to provide large peak currents and stable voltages even when delivering high output power. Heat sinks have been cleverly integrated into the chassis to optimize heat dissipation assuring perfect operating conditions. Its outstanding specifications, imposing size and weight (50kg) is followed by refined and stylish curves that makes this anodized aluminium piece of art remarkably stand
