Stereo Amplifier - Audiolab 8300A

At this amplifier's heart is a powerful dual-mono amplifier delivering 75W per channel into eight ohms. CFB or "Complementary Feedback" topology offers superior linearity and ensures excellent thermal stability.

ACD or "Active Current Drive" means current limiting is under microprocessor control, programmed to allow the amplifier to supply high currents into complex loads, on par with amplifiers that are bigger and more powerful on paper.
