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 speakers motion control, even when driving 2Ω loads.

The audio performance
To achieve its remarkable sound quality, the NEXT MA series output circuits were engineered as a high bandwidth, very low bias and feedback class AB or H (MA3200 andMA3800), using the highest grade linear output devices. This approach yields outstanding studio-quality sound accuracy and detail.
