Build quality that's off the charts

The massive heatsink tells you right away that this is a serious amp. Inside, the multi-layered circuit board is laid out in short, dedicated signal paths to deliver only the purest signal in the fastest time. Brax uses silver solder to secure each discretely mounted component for the best conductivity possible between them. Gold-plated connections eliminate corrosion to keep the signal flowing freely in or out of this amplifier.

Hi-fi features

Because handling music properly takes such a delicate touch, you won't find any crossover filters or bass boosts in this amp to color or sidetrack the sound from its final destination. Two separate power supplies ensure stability and dependability. The output power transistors have been hand-selected and measured to match each other so your music will sound consistent and strong. You'll want to display this amp proudly in your system. Hand-made in Germany, each MX-4B amplifier comes with its serial number custom milled into the top nameplate.
