The amplifier has a complete dual-mono configuration starting from the two 1200VA toroidal transformers specifically designed for low dispersed flow. Uses our SeGeSTA (Single Gain Stage Transconductance Amplifier) configuration followed by a group of four transistors to provide all the necessary current without affecting the gain stage performance. The amplifier does not use global feedback. The 4-layer printed circuit has been designed so that the input signal never crosses the output signal and that the sensitive amplification stages are as far from the power transformers as possible. All components are of the highest level, starting from military standard resistors to continue with the capacitors on Airtech specification up to the wiring made of 7N OCC copper and to the pure copper and gold-plated connectors.

Technical description

Zero Global feedback, all stages fully balanced, dual-mono configuration and discrete components circuits, power stage with 12 bipolar transistors per channel, 56000μF filter capacity per channel, oversized military resistors to minimize thermal distortion, "audiograde" capacitors on Airtech specifications, microcontroller management.
