Its core highlight lies in its amazing driving power, featuring up to 7600mW balanced output power, capable of easily driving the vast majority of high-impedance full-sized headphones on the market while maintaining extremely low distortion and noise.

Beyond its powerful hardware qualities, the DX5 II has fully evolved in functionality. It introduces professional-grade 10-band high-precision PEQ adjustment. With dedicated desktop software, users can finely tune frequency, gain, and bandwidth to match headphone characteristics or personal listening preferences. In terms of wireless connectivity, it supports LDAC Bluetooth 5.1 high-resolution transmission, ensuring wireless playback possesses CD-level sound quality. Coupled with the new 2.0-inch full-color Aurora UI interface and rich input/output ports, the Hi-Res DAC & Headphone Amp DX5 II is undoubtedly the ideal core for building a high-end desktop Hi-Fi system.

Core Advantages and Application Scenarios

Ultimate Decoding & Self-Developed I/V Circuit: Restoring True Sound
The DX5 II utilizes two of ESS's latest ES9039Q2M decoding chips, responsible for the left and right channels respectively, effectively enhancing channel separation and dynamic performance. Paired with TOPPING's self-developed I/V (Current/Voltage) conversion circuit, this module is designed specifically for superior audio reproduction. It not only significantly reduces distortion and noise but also optimizes circuit layout. This allows the DX5 II to exhibit rich layering and micro-details when processing complex symphonies or delicate vocals, making it the top choice for audiophiles pursuing original sound reproduction.

Monster-Level Driving Power & Wide Headphone Compatibility
To meet the driving needs of different headphones, the DX5 II is equipped with an X-Hybrid headphone amplifier circuit, providing a robust output power of up to 7600mW x 2. The unit features 6.35mm single-ended, 4.4mm balanced, and 4-Pin XLR balanced output ports, offering full compatibility with various connectors. More importantly, it boasts an ultra-low noise floor as low as 1.8uVrms. This means that even with extremely high-sensitivity In-Ear Monitors (IEMs), no background hiss will be heard during quiet musical passages; meanwhile, when facing high-impedance headphones, it provides ample energy and dynamic control.

Professional 10-Band PEQ: Customize Your Listening Experience
The DX5 II supports advanced 10-band PEQ (Parametric Equalizer) adjustment functions. Through TOPPING's new PEQ algorithm and dedicated desktop software, users can precisely adjust the frequency point, gain, and bandwidth (Q value) of each band. This feature can be used not only to correct frequency response defects in headphones but also to customize a unique sound signature based on different music genres (such as enhancing bass for electronic music or highlighting mids for vocals), with support for saving profiles to multiply the fun.

All-Round Connectivity Center & Preamp Mode
As a desktop audio hub, the DX5 II features multiple input methods including USB, Optical, Coaxial, and Bluetooth. The USB input uses the XMOS XU316 chip, supporting up to PCM 768kHz/32bit and DSD512 native decoding. Additionally, it features a "Preamp mode," allowing direct connection to active speakers or power amplifiers with volume control via the knob. It supports a 12V Trigger interface for synchronized power on/off with other devices, realizing the convenience of one-touch startup for the entire Hi-Fi system.
