Bacillus II+ features a triple-reinforced power supply, true dual-mono design and fully balanced architecture for clear, dynamic, precise sound.
Fully balanced dual-mono headphone amplifier with triple-reinforced power supply
The Bacillus II+ takes the engineering of its smaller sibling, the Bacillus II, to a new level. With a triple-reinforced power supply—separated for each channel and the auxiliary electronics—it delivers a true dual-mono design for exceptional clarity and channel separation.
Its fully balanced architecture doubles speed and power, resulting in playback that is as dynamic as it is precise. For maximum flexibility, it also provides single-ended inputs and outputs.
A robust metal chassis shields against magnetic interference and ensures long-term durability. Elegant wood side panels add a refined touch and integrate seamlessly with the amplifier line’s signature design language.
