Topping DX1 II Black

TOPPING DX1 II｜Desktop DAC Headphone Amplifier with Gaming Tuning and 10-Band PEQ DSP

A desktop DAC headphone amplifier that balances gaming positioning, Hi-Res decoding, and headphone driving power

The TOPPING DX1 II is a desktop DAC headphone amplifier from TOPPING, built around an ESS ES9039Q2M DAC and XMOS XU316 USB architecture. It supports PCM 384kHz, DSD256, and delivers up to 1000mW x2 @ 32Ω from its 4.4mm balanced headphone output. For users who want accurate in-game footstep positioning, strong music detail retrieval, and quiet performance with high-sensitivity IEMs, the DX1 II is more than just a decoder—it is a multifunction audio hub integrating 10-band PEQ DSP, preamp functionality, and voice chat support.

Compared with traditional USB DACs that only offer a fixed sound signature, the TOPPING DX1 II uses adjustable DSP and independent left/right channel PEQ parameters to achieve more precise game soundstage correction and personalized headphone tuning. Compared with DAC/AMPs in the same price range that only provide basic headphone output, the DX1 II stands out by integrating PS5 compatibility, Nintendo Switch compatibility, 3.5mm TRRS microphone voice chat, plus optical input/output and preamp application capability, offering significantly greater flexibility.

Who should buy the TOPPING DX1 II?

User Recommendation Analysis (Click to expand)

▼

Who Should Buy

FPS or tactical shooter players who want to enhance footsteps, spatial positioning, and left/right channel detail, and want to create multiple PEQ presets
Desktop audio users who need one device that can drive headphones, connect active speakers, and also serve as a preamp and DSP audio hub
PC gamers and music lovers who already own decent headphones or IEMs and want to upgrade from onboard audio to a lower-noise, higher-resolution USB DAC
Multi-platform users who rotate between PS5, Nintendo Switch, and computers and want one device for plug-and-play switching

Who Should NOT Buy

Users who already own a mid- to high-end balanced DAC/headphone amp and a separate DSP processor, and whose current system is already fully featured
People who only want the most basic entry-level listening setup with no EQ adjustment or mode switching, and have no need for DSP, preamp functions, or multiple connectors
Users who rely purely on Bluetooth headphones or wireless speakers and do not plan to build around wired headphones, active speakers, or a console audio chain

TOPPING DX1 II Core Technologies and Features

10-band high-precision PEQ DSP: Built-in gaming-focused 10-band parametric EQ allows adjustment of frequency, gain, and bandwidth, with independent left/right channel settings for different presets tailored to footsteps, directional cues, music listening, speakers, and headphones.
ES9039Q2M high-resolution DAC architecture: Uses the ESS ES9039Q2M DAC chip paired with an XMOS XU316 USB processor to provide clean, transparent decoding with support for PCM up to 384kHz and DSD256 high-resolution playback.
Fully balanced four-channel headphone amplification circuit: The headphone amp stage uses a four-channel fully balanced architecture with independent left/right channel processing to reduce crosstalk and improve separation and soundstage positioning, especially for gaming and detail-focused listening.
4.4mm balanced high output power: The 4.4mm balanced headphone output delivers up to 1000mW x2 @ 32Ω, offering strong control, transient response, and dynamic performance for both high-sensitivity IEMs and harder-to-drive headphones.
Ultra-low noise floor design: Features a patented low-noise separated power supply design and optimized analog circuitry. The official specification states a noise floor below 0.9μVrms, helping high-sensitivity in-ear monitors maintain a quiet background.
Dual UAC 1.0 / UAC 2.0 modes: Switchable UAC 1.0 and UAC 2.0 modes improve plug-and-play compatibility with PS5, Nintendo Switch, PC, Mac, tablets, and other devices.
3.5mm TRRS voice chat support: The 3.5mm TRRS connector supports headsets with microphones for high-quality playback and clear voice communication at the same time, with microphone input supporting up to 24-bit/192kHz.
DAC, DSP, and preamp in one: In addition to headphone listening, the DX1 II can also function as a desktop preamp and DSP processor, making it suitable for active speakers, power amplifiers, TVs, CD players, and streaming devices.
Integrated optical input / output: Includes optical input and optical output, allowing external digital signals to be routed in for PEQ processing while also integrating consoles, TVs, and digital playback systems.
RCA and 4.4mm line outputs: Provides RCA and 4.4mm line outputs for convenient connection to active speakers or power amplifiers, enabling a desktop 2.0 setup or dual headphone/speaker system.
Single-cable USB-C power and data: A single USB-C cable handles both audio transmission and power delivery, keeping desktop cable management cleaner and reducing the need for extra adapters and wiring.
Infrared remote control: Built-in infrared remote support allows volume and playback control without additional pairing, making it convenient for desktop, living room, or console-side use.

10-Band PEQ DSP Gaming Tuning System

Allows high-precision parametric EQ adjustment of frequency, gain, and bandwidth. This is more than simple bass/treble tweaking—it enables precise correction of headphones and in-game soundstage.
Supports independent left/right channel adjustment, making it especially useful for players who want to fine-tune positional cues, compensate for hearing differences between ears, or create specific competitive presets.
You can create different sound profiles such as footstep enhancement, directional cue emphasis, music listening, speaker mode, and headphone mode, all managed through TOPPING Tune software.

ES9039Q2M DAC and XMOS XU316 Decoding Platform

The ESS ES9039Q2M DAC chip provides a high-resolution, low-distortion, highly transparent sonic foundation suitable for mixed gaming, music, and multimedia use.
The XMOS XU316 USB processor handles efficient USB audio transmission and supports PCM up to 384kHz and DSD256 to meet Hi-Res music playback needs.
For users upgrading from onboard audio or a basic USB sound card, it can noticeably improve background cleanliness, detail layering, and sound definition.

4.4mm Fully Balanced Headphone Amplifier Output

The headphone amplification stage uses a four-channel fully balanced architecture with independent left/right channel processing, helping improve channel separation, positional accuracy, and overall control.
The 4.4mm balanced headphone output can reach up to 1000mW x2 @ 32Ω, providing sufficient driving headroom for low-impedance high-sensitivity IEMs as well as some high-impedance over-ear headphones.
In gaming, it can present more stable left/right positioning and spatial outlines; in music, it helps with dynamic extension and bass control.

3.5mm TRRS Voice Chat and Headset Integration

The 3.5mm TRRS connector supports headsets with microphones for two-way audio needs such as in-game voice chat, livestream communication, and online meetings.
Microphone input supports up to 24-bit/192kHz, balancing voice clarity and playback quality without requiring a separate basic sound card.
For console gamers or desktop gamers, this can reduce the number of devices and simplify cable setup.

Preamp, Optical, and Multi-Output Desktop Integration

The DX1 II is not just a headphone amp; it can also serve as a desktop preamp and DSP processing center, making it suitable for active speakers or power amplifiers.
Optical input / output can integrate TVs, CD players, streaming devices, and game consoles, allowing external digital sources to benefit from PEQ processing as well.
RCA and 4.4mm line outputs provide greater system expandability, making it easy to build a desktop audio setup where headphones and speakers coexist.

USB-C Plug-and-Play and Console Compatibility

The single-cable USB-C design handles both power and audio transmission, making installation faster and desktops tidier, especially beside laptops and consoles.
Supports UAC 1.0 / UAC 2.0 mode switching for multi-platform use with PS5, Nintendo Switch, PC, Mac, and tablets.
Includes infrared remote control for quick volume and playback adjustments in desktop or living room scenarios, without waiting for Bluetooth pairing.
