The AT-PHA100 portable headphone amplifier with built-in USB DAC is engineered using innovative, hand-selected audio components together for superb sound reproduction. Compatible with PCM 384 kHz/32 bit and high fidelity DSD sources, the AT-PHA100 gives headphones a rich, detailed boost throughout the sonic range with ultra-low distortion. Equipped with both analog and digital inputs (3.5 mm jack and USB micro-B, respectively) and 3.5 mm headphone jack, it also features a high/low gain switch, machined aluminium volume knob, and five-stage sampling indicator for digital input.

The internal lithium polymer rechargeable battery lasts up to 14 hours when amplifying an analog signal, and up to 6 hours when amplifying a digital signal. The amplifier comes with two rubber bands and a rubber mat for strapping the unit to a smartphone or other portable device, a 1.0 m USB cable (USB 2.0 to USB micro-B) and a 10 cm audio cable terminating in a 3.5 mm gold-plated stereo mini plug at each end.
