The MA series power supply uses high current toroidal transformers and a huge capacitor bank to ensure an unusually high amount of stored energy. This makes a critical difference in sound quality, allowing for incredible transient response and motion control of the speakers, even when driving 2? loads. To achieve their remarkable sound quality, the NEXT MA series output circuitry was designed as a high bandwidth, very low bias, and feedback class AB or H (MA3200 and MA3800), utilizing linear output devices of the most advanced. high quality. This approach produces exceptional studio-quality sound detail and precision.
