Topping DX5 II DAC & Headphone Amplifier

We are pleased to inform you about the latest enhancements to our DX5II model:

• Home App integration – enabling smart control and monitoring via your mobile device;
• Headphone Crossfeed function – a convolution‑based algorithm that precisely simulates HRTF and room acoustics, significantly improving imaging accuracy and spatial depth while reducing the typical in‑head listening effect. (A simplified BS2B‑based mode is also available for a more speaker‑like presentation.)

Dual ES9039Q2M

Each channel (left and right) utilizes an independent ESS new DAC chip-ES9039Q2M. This design delivers higher SNR, greater DNR, and lower distortion compared to the DX5, offering high-resolution audio performance.

X-Hybrid Headphone Amplifier Circuit
X-Hybrid represents a new technological breakthrough following NFCA architecture. Utilizing an all-new triple-stage hybrid amplification design, it not only retains the signature ultra-low distortion and high dynamic range of the NFCA, but also achieves significantly improved efficiency by optimizing circuit topology-resulting in reduced static power consumption and heat generation. Despite its compact chassis, it houses a fully balanced, quad-channel amplifier

Wide range of adaptation to Headphones
DX5 II is equipped with 6.35mm single-ended, 4.4mm balanced, and 4-pin XLR headphone jack, meeting the needs from low sensitivity headphones to high-sensitive IEMs. With a low noise floor of just 1.8uVrms, even the most sensitive IEMs remain free from any audible background hiss. Delivering a powerful 7600mW x 2 output, DX5 II allows most headphones to reach their full performance potential.

Ten-band high-precision PEQ adjustment
We develop a brand new PEQ adjustment that supports ten customizable frequency bands. Topping's brand new PEQ algorithm and desktop software allow you to fine-tune the frequency, gain, and bandwidth of each PEQ band. The software supports the import of target curves and raw curves, and enables curve compensation using the target curve. It can also save multiple profiles for easy switching. All outputs support independent PEQ configuration, and both headphones and speakers can be accurately adjusted to the ideal state.

LDAC Bluetooth Playback
Equipped with QCC5125 chip, DX5 II supports Bluetooth 5.1 and can support up to 96kHz/24bit. Also it fully supports LDAC/aptX-Adaptive/aptX/aptX HD/AAC/SBC and other audio encodings, allowing high-quality audio to be transmitted wirelessly to provide a music experience beyond CD level.

Plug and Play
DX5 II has a wide range of compatibility and apply to various operating systems such as Windows 10, Windows 11, MAC, Linux and iOS/Android. The USB hardware is based on third generation XMOS XU316 and Thesycon driver*. It's stable and reliable. In addition, the USB input supports up to PCM768kHz/32bit and DSD512, which makes every detail vivid.

Self-developed IV circuitry unlocks full DAC potential
Our self-developed I/V conversion module is dedicated to achieving superior audio reproduction. The exceptional circuit design delivers lower distortion and noise while occupying less space. Pushing the boundaries of physical limits, this design extracts the maximum performance from the DAC chip.

Directly connect Active Speakers
DX5 II also features a "preamp" mode. In preamp mode, you can adjust the output volume of DX5 II, then connect it directly to a pure amplifier or active speaker without the need for a separate preamplifier. Both input and output interfaces of the DX5 II come with volume memory functionality, enabling the device to automatically restore the last set volume when switching outputs-allowing for a quick return to your familiar listening environment.

12V Trigger
DX5 II is equipped with 12V Trigger input and output, which support being triggered by other devices, as well as actively triggering other devices to switch on and off synchronously.
