Powerful performance

another step up

Inheriting the high-performance DNA of the KA17, the QX11 delivers further optimizations in sound quality, power efficiency, and user experience. As the newest member of the QX series, it represents both a continuation of proven excellence and a new starting point for portable HiFi.

End-to-end TI audio architecture, Powerful and stable performance

The QX11 combines dual TI OPA1692 op-amps in the voltage gain stage with four parallel TI OPA1622 op-amps for headphone output, achieving ultra-low noise, ultra-low distortion, and outstanding driving power. The fully integrated Texas Instruments audio architecture brings out rich detail, expansive dynamics, and consistently stable performance.

End-to-end independent powering, For clean, transparent sound

The QX11 employs a four-stage precision power supply design that filters out power ripple and noise stage by stage. Digital and analog circuits also use independently partitioned power supplies equipped with multiple high-precision, low-noise LDOs. The same power-supply layout used in professional headphone amplifiers delivers stable, abundant energy and provides a solid foundation for high sound quality.
