Can the world’s best amplifier be made even better? Our engineers faced this enormous challenge when developing the MX4 PRO. At the level of a BRAX product, every detail must be constantly scrutinized and optimized, even if it seems insignificant at first glance. Only in this way is it possible to continually push the boundaries – both sonically and technically. Ultimately, we succeeded in redefining the standards in amplifier construction with the MX4 PRO. It is the perfect symbiosis of state-of-the-art components and ingenious circuit improvements, without neglecting the previous virtues and traditions for which the BRAX brand enjoys the highest reputation worldwide.
It is therefore still a matter of course that Audiotec Fischer is the only manufacturer to use exclusively hand-selected transistors for the production of every BRAX amplifier. These transistors are classified into over 300 classes using proprietary measuring instruments and assembled accordingly. This unique process not only guarantees the smallest series tolerances, but above all unique measurement and performance values.
