The MA series amplifiers are the result of near 15 years of experience of a skilled European team and the adoption of the most recent production technologies. This ends in a product of unsurpassed performance, extreme reliability at an extremely competitive price.

The supply
The MA series power supply uses high-current toroidal transformers and a huge capacitor bank to ensure an uncommonly high amount of stored energy. This makes a critical difference in sound quality allowing incredible transient response and speaker’s motion control, even when driving 4 ohm loads.

The audio performance
To achieve its remarkable sound quality, the MA series output circuits were engineered as a high bandwidth, very low bias and feedback class AB or H (MA-900 and MA-1000), using the highest grade linear output devices. This approach yields outstanding studio-quality sound accuracy and detail.

Main external features
