The Bacillus II is our entry-level headphone amplifier, yet it’s designed for those who want more from a compact setup. Outfitted with high-grade input capacitors and premium op-amps, it delivers a sound profile that combines warmth with speed, punch, and impressive detail.
Versatile enough to pair with headphones of any impedance, the Bacillus II ensures a smooth and dynamic listening experience. With an exceptional ability to reveal subtle nuances, it distinguishes tonal variations and enhances details, capturing the richness in every note that many amplifiers miss.
Its unique design—featuring a large, original volume knob, an angled top, and wooden side panels—makes the Bacillus II a stylish addition to any desk.
