The FiiO Q1MKII is a compact digital-to-analog converter (DAC) and amplifier designed to enhance audio playback from various devices. It features a range of inputs and outputs including 3.5 mm for both input and output, a 2.5 mm balanced output, and a USB/OTG DAC connection. With a single AKM4452 DAC chip and OPA1662 and OPA926 amplifier chips, the Q1MKII supports high-quality audio up to 384kHz/32bit PCM and DSD256. Its low output impedance ensures compatibility with a wide range of headphones. The device employs a digitally-stepped volume knob to minimize channel imbalance and includes a bass boost feature that can enhance low frequencies but may thicken vocal clarity. While designed for easy plug-and-play functionality, compatibility with Android devices is contingent upon specific device capabilities, particularly for USB OTG. The unit also features a gain switch to adapt to different headphone requirements. Finished in an anodized metal case, it provides additional electromagnetic interference shielding. Despite the absence of Bluetooth connectivity and some tight audio jacks, the overall performance, build quality, and price point make the Q1MKII a compelling choice for audio enthusiasts.
