The MMA-4 has been designed as an audiophile pre-amplifier with a minimum of electronics in the signal path. Design objectives included consistently good sound over the whole range of gain settings, a high level of transparency and ultra-low noise and distortion.

The MMA-4 was developed in association with engineer/producer Leif Mases. Leif's work with a diverse range of artists including Abba, Led Zeppelin and Black Sabbath is demonstrated by the MMA-4's design with the engineer in mind.
