We’ve developed the MA04 series amps in pursuit of the highest fidelity, power density and stability possible. Featuring our high efficiency Class I™ power modules, a premium quality heavy-duty toroidal transformer power supply and the highest grade components, the MA04 series power amps deliver an enormous amount of power with unmatched sonic quality. Even at continuous operation in the most critical working conditions. These amps are also equipped with SAE Audio’s robust Ultra Low-Loading Capacity technology, so the MA04 series is an ideal power stage for high SPL sub applications.
