ABOUT THE MPA 400 AMPLIFIER
Power amplifier MPA 400 is the next achievement of Struss Audio company. This amplifier is direct response to market requirements for powerful yet detailed and musical power stage.
The MPA400 amplifier is the result of several years of work of the STRUSS AUDIO team. Its construction is based on more than thirty years of experience and knowledge of the designer and owner of Struss Amplifiers, Zdzisław Hrynkiewicz Struss.
After many years of trials and improvements Struss Audio developed spatial system of chassis, where each individual electronic and mechanical component is carefully positioned. This allowed to obtain the shortest possible connections between the elements, high resistance to interference, very good cooling and thermal stability.
Interesting design of the amplifier casing has also been developed.
MPA400 is based on bridge configuration of two monoblocks previously implemented in DM250 integrated amplifier. This together with two 500W transformers in power supply, allows to drive any loudspeaker with low efficiency or so called “difficult” characteristics.
The design underlying the MPA400 was developed in 2000 and has been used in the latest Struss Audio amplifier models, with changes due to new technologies and production requirements.
Unique utilisation of patented topology of electronic circuit allows to achieve very musical and detailed sound with unique holographic detailed sound stage. Also low frequencies are performed with power and excellent control.
MPA400 is good match for every high quality source of audio signal and offers transparency and non-altered audio performance. It can be also interesting option for tube preamplifiers or sound sources, offering exact reproduction of input signal, without any coloration or own timbre. In such case the tube sound characteristics is fully reflected on high power output, with wide frequency range and high dynamic sound.
