The Head 2 is a distinctive tube-informed headphone amplifier from Trafomatic Audio, a well-established Serbian manufacturer known for characterful tube electronics engineering, built with a wide bandwidth. The Head 2 brings Trafomatic's considered engineering to dedicated tube-informed headphone amplification.
Key specs that matter
Maximum power is a modest 2mW into 50 ohms - a classic single-ended-triode-style figure reflecting characterful, low-power tube design. Frequency response spans a wide 10Hz to 80,000Hz within plus-or-minus 3dB. Gain is 26dBu. Total harmonic distortion is 0.2% at 1V RMS into 300 ohms. Signal-to-noise ratio is 88dB. Output impedance is selectable across 25, 50, 100, 300, or 600 ohms - a versatile matching option for different headphone impedances. At 400 x 310 x 100mm and 10kg, the Head 2's considerable weight for a headphone amplifier reflects serious internal transformer engineering consistent with quality tube design.
Sound and use context
Expect the warm, richly textured character tube amplification is broadly celebrated for, with the versatile selectable output impedance allowing precise matching to a variety of headphone types.
Pairing
The versatile selectable output impedance accommodates a variety of headphone impedances for optimal sonic matching.
Alternatives
Other manufacturers' tube-informed headphone amplifiers offer alternatives for buyers wanting to compare features at a similar price point.
