This is an ex-demo unit from a shop. It is fully functional, but might have some signs of use, although in excellent shape. Comes with 5-year warranty like new units.

Small, compact and robust, the Bacillus is a precision grade class-AB headphone amplifier that comfortably adapts to any impedance headphones. The bright profile is quick in transitions and urges a direct sound, most notably in rock genres. But the low distortion also adapts quickly to acoustic and delivers a very realistic and intimate experience. 

All in all, Bacillus is an impressive performer and thanks to its diminutive size is an ideal road companion for travelling sound professionals. The Bacillus might be our entry-level headphone amplifier, but on looks and performance you could be forgiven for thinking this elegant headphone amp is among our high-end range – it’s only our generous price tag that gives the game away.
