Calaf, the biggest output power integrated in solid-state amplifier line of Consonance, there is very little headroom available beyond the conditions under dynamic for Calaf. Massive toroidal transformer with independent secondary windings and a bank of eight 10,000uF electrolytic reservoir capacitors for each channel's main power supply. There are also independent preamplifier sections for each cannel and both of these have their own power supplies. Both left and right channels are bulit as mono power amplifiers, each with seven pairs of high-current transistors mounted onto a thick copper bus bar. This is bolted onto the extruded heatsinking that's visible either side of the amplifer.
Combined the advantage of class AB and the class A technology, the Cool Class A technology actually achieved same linear sound performance essentially but without normal need of big electrical current, as Class A does.
