audiolab pulls no punches with the genuine nature of our power rating. The 7000A’s discrete Class AB power amp stage delivers 70W per channel into eight ohms, with a maximum current delivery of 9A amps into difficult loads. A new standard in audiolab amplifiers, the output stage of the discrete power amp circuits uses a CFB (Complementary Feedback) topology, ensuring superior linearity and excellent thermal stability, as the idle current is kept independent of the temperature of the output transistors. Critically specified by Jan Ertner (lead engineer for the audiolab brand); the newly developed power supply features a substantial 250VA toroidal transformer, followed by 4x15000uF reservoir capacity (60000uF in total), helps the amp to maintain firm control of the music whilst enabling excellent dynamic range.
