Erzetich – Bacillus II +

The Bacillus II + takes the technology of its smaller brother Bacillus II to an entirely new level. With a triple-reinforced power supply—dedicated to each channel and the auxiliary electronics—this amplifier boasts a true dual-mono design, delivering unparalleled clarity and separation in sound.

But Erzetich didn’t stop there. The architecture is now fully balanced, doubling both the speed and power for a performance that’s as dynamic as it is precise. Need unbalanced inputs or outputs? They’ve got you covered for ultimate flexibility.

Encased in a robust metal body, the Bacillus II+ is built for durability and magnetic shielding. The elegant wooden side panels not only add a touch of sophistication but also tie it seamlessly to our signature amplifier design.
