Features
8W of Balanced Power
Up to 8W of output power to drive all planar headphones. Pitch-black noise floor. Super-low audio distortion. Balanced and unbalanced headphone outputs. 1/4″ single-ended and 4.4 mm Pentaconn output jacks to accommodate any headphones on Earth, including hard-to-drive ones.
Variable Tube Drive
Class A is so squeaky-clean, it will satisfy the hard-core fans of sonic purity. But watch what happens when you add some old-timey tube warmth to your favorite tunes! The Drive dial delivers the slick growl without raising the volume. Turn the dial and don’t be surprised if you feel transported back in time!
Smart Class-A
Plug in your headphones and Amp mini will deliver optimal performance. It smartly shifts from Voltage mode to Current mode to match your headphones’ sensitivity and impedance. This maintains excellent Class A linearity, while minimizing heat — a real breakthrough in sound quality and energy savings!
Fly-by-Wire Controls
The large volume knob delivers a smooth, satisfying feel thanks to the internal hydraulic pressure-absorbing system. The channel balance will stay the same at any volume level. Everything inside Amp mini is microprocessor-controlled (fly-by-wire), meaning silent adjustments and precise control.
Tube Rolling
Enjoy High-Res content as you work at your desk! Amp mini™ stacks with our DAC mini™, as well as Mac Mini™ and Mac Studio™ from Apple™, creating a slick desktop system your friends will envy. Ready to customize? Roll the tubes using either 12V or 6V models, such as 12AX7, 6BC8, etc.
