HeadAmp Pico DAC/Amp, Power & Slim

HeadAmp’s smallest amplifier at just 9.4 millimeters thick, the Pico Slim is an ideal companion for IEMs and low-impedance headphones. Its advanced circuitry creates a jet-black background for relaxed listening, and its special technology helps maintain perfect channel matching, even at very low listening levels. The chassis is milled from solid aluminum for a robust build that’s made to travel, and complete with a unique 255-step volume control and a powerful battery capable of 60 hours of playback time.

The all-time best seller from HeadAmp, the Pico DAC/amp offers clean, clear, powerful sound from a compact, handcrafted body. Equipped with a high-end Wolfson chipset, a two-cell lithium-ion battery, a low-noise circuit, and the kind of analog output that's rarely included in a portable amplifier, this up-sampling USB DAC/amp delivers an audio quality you might expect from a full-size component. The built-in battery offers approximately 30 hours of playback between charges, and the gain switch allows for pairing with both low-impedance headphones and IEMs and higher-impedance sources. From design to fabrication to assembly, the Pico is made entirely in the US, and the construction has an industrial, high-precision aesthetic. Of the build quality, InnerFidelity says, “Justin of HeadAmp is a notorious perfectionist and it shows.”

Among the most powerful portable headphone amps on the market, the Pico Power offers the highest sound quality of any amp in the Pico family. It delivers 18 volts of power and features a discrete diamond-buffer output stage with hand-matched transistors and current sources. Its low output impedance, very low noise floor, and three-way gain switch make it well suited for a wide range of dynamic headphones, from sensitive IEMs to full-size cans like the Sennheiser HD 800 and HiFiMAN HE series. Precision machined from a solid block of aluminum, the enclosure is complete with a satin finish and built to weather years of use. The included 9V alkaline batteries provide 40 hours of listening, and you can also swap in lithium rechargeable batteries (not included) for 30 to 50 hours of battery life per charge. Like the Pico Slim and the Pico DAC/amp, the Pico Power is made in the USA.
