Desktop-Grade DAC
The ESS Sabre Pro ES0927PRO chip features a fully differential audio architecture design with 8 channels set up in parallel. It is paired with a pair of ultra-low-noise ES9312 regulators for precise output matching on each audio channel. Audio signals are accurately restored thanks to this pair of chips' optimized power efficiency and effectiveness in reducing clock jitter.

High-End TI Op-Amps
The QX13 features four wafer-level INA1620 precision amplifier chips, strategically arranged in a custom internal layout to drastically reduce crosstalk, even under demanding conditions. This design ensures cleaner channel separation and enhanced clarity. Complementing this are two low-distortion OPA1692 op-amps, delivering consistently dynamic performance across a wide range of load scenarios.

Patented Desktop Mode
Thanks to its advanced configuration, optimized audio circuitry, and improved heat dissipation, the QX13 delivers desktop-class power in desktop mode, rivaling full-size headphone amplifiers while maintaining exceptional energy efficiency. It also features a high-precision power meter that intelligently evaluates the capabilities of connected USB power sources, automatically adjusting gain and output to ensure optimal performance for any setup.

Digital and Analog Separation
To ensure precise and dynamic signal processing, the QX13 separates its digital and analog boards and shields them with an isolation cover. This not only minimizes interference between circuits but also enhances thermal management by efficiently absorbing and dissipating heat, allowing the QX13 to maintain stable, high-power output over extended use.
