Desktop-grade DAC
ESS SABRE PRO – Flagship Series ES9027PRO
Features a fully differential audio architecture with 8 channels in parallel, paired with dual-channel ultra-low noise regulators (ES9312) to precisely match the output of each channel. Optimized power efficiency and reduced clock jitter significantly improve audio signal fidelity.
*The ESS SABRE PRO series DACs are primarily used in high-end audio systems and professional audio equipment. The latest generation includes the new flagship series ES9039PRO and ES9027PRO.
6 Ti Audio Operational Amplifiers
New Combination – High-Energy Stable Output
The preamplifier uses two low-noise audio operational amplifiers, OPA1692, paired with four wafer-level high-precision matched INA1620s for power amp driving. Based on a specially designed internal layout, crosstalk is significantly reduced, and even under overdrive or overload conditions, it is unaffected by inter-channel interactions, ensuring excellent dynamic range under various load conditions.
Each INA1620 features:
8 0.004% high-precision matched thin-film resistors
1 on-chip EMI filter
1 low-distortion, high-output-current dual-channel audio operational amplifier
Patented Desktop Mode
Self-Adjusting and Scheduling, Balancing Efficiency and Power Consumption
Thanks to its new configuration, optimized circuit architecture, and more efficient heat dissipation, the QX13 delivers powerful output comparable to a desktop amplifier in desktop mode, while significantly reducing power consumption. It also features a built-in high-precision power meter that accurately determines the power supply capability of different USB front-ends, intelligently adjusting the headphone amplifier’s power supply, gain, and output power.
Patent No.: ZL202321946664.8
Front Type-C Interface: Data Transfer + Power Supply Interface
Side Type-C Interface: Dedicated Interface for External Independent Power Supply
Digital-Analog Separation, Multi-Layer Masking
The design separates the digitizer and analog board, equipped with a mask for isolation. This effectively ensures the accuracy and dynamics of signal processing while effectively absorbing and conducting heat for efficient heat dissipation, ensuring the QX13 can deliver sustained high-performance output.
XMOS XU316 Core, Ingenious Design
Professional-grade USB AUDIO performance, high performance, low latency, supporting 768kHz/32bit, DSD512 (Native) decoding specifications; paired with dual ultra-low phase noise, low-temperature femtosecond crystal oscillators, it stably adapts to various audio sources and sampling rates. A 10-band lossless PEQ adjustment has also been developed based on the XMOS XU316, supporting adjustment via Web* and the Android FIIO Control APP, allowing for easy tuning.
Professional Audio Architecture, Comparable to Professional Decoding Amplifiers
The QX13 condenses the signal processing of mid-to-high-end decoding amplifiers into a small dongle, achieving high-precision conversion from frequency multiplication digital audio to DAC. It also features multi-stage analog audio processing including LPF voltage amplification, BUF current amplification, and parallel enhanced current amplification, delivering sound quality comparable to professional decoding amplifiers.
Full Ecosystem Accessories, The Essence of Portable HiFi
Standard magnetic leather protective case, perfectly compatible with iPhones. Android phones can be used with the included magnetic plate for a magnetic effect. (Two curved magnets are located on the back of the case.)
