Choosing between the TOPPING DX5 II and TOPPING DX1 II can be confusing at first. Both are compact DAC and headphone amplifier solutions, both use the new-generation ES9039Q2M DAC, both support high-quality headphone playback, and both feature 10-band PEQ for detailed sound customization, And all support TOPPING Home Web.
However, they are designed around different use cases.
The TOPPING DX5 II is a more powerful, feature-rich desktop DAC and headphone amplifier for users who want a complete central hub for headphones and active speakers.
The TOPPING DX1 II takes a different approach: it combines a compact USB DAC and headphone amplifier with optical I/O and DSP functionality, making it particularly useful for gaming, desktop systems, and adding PEQ processing to existing audio equipment.
So which one fits your setup? Let's look at the key differences.
1. Choose TOPPING DX5 II for a Complete Desktop Audio Hub
The TOPPING DX5 II is designed to sit at the center of a desktop audio system.
It combines a high-performance DAC, powerful headphone amplifier, preamp functionality, Bluetooth, multiple headphone outputs, PEQ, display controls, and 12V Trigger in one compact unit.
This makes it particularly suitable if your setup includes more than just a computer and headphones.
For example:
PC → DX5 II → Headphones
or
PC / TV / Streamer → DX5 II → Active Speakers
or
Digital Source → DX5 II → Power Amplifier → Passive Speakers
The TOPPING DX5 II can operate in preamp mode, allowing its volume to be controlled directly when connected to a power amplifier or active speakers. This means you don't necessarily need a separate preamplifier for a compact desktop system.
Why DX5 II fits this type of user?
You use multiple types of headphones.
You want 6.35mm, 4.4mm balanced, and 4-pin XLR headphone connections.
You need substantial headphone amplifier power.
You want to connect active speakers or a power amplifier.
You want Bluetooth with LDAC and other codecs.
You prefer a color display and physical controls.
You want a more complete desktop audio control center.
You plan to build a more advanced headphone or speaker setup.
For users who want one device to handle most of their desktop audio needs, the DX5 II is designed for this role.
2. Choose TOPPING DX1 II for a Compact PC and Gaming Setup
The TOPPING DX1 II focuses more heavily on simplicity, flexibility, and DSP functionality.
It connects to a computer, tablet, or compatible gaming device through USB-C and provides 3.5mm single-ended and 4.4mm balanced headphone outputs.
Its compact USB-powered design makes it easy to integrate into a desktop setup without adding a large external power supply.
For example:
PC → USB → DX1 II → Headphones
Or for gaming:
Gaming PC → DX1 II → Gaming Headset
The 3.5mm connection supports standard headphones as well as TRRS gaming headsets with microphone input, allowing compatible headsets to handle both game audio and voice communication through one connection.
The TOPPING DX1 II also supports UAC 1.0 mode, making it compatible with devices such as the Nintendo Switch and PlayStation 5.
Why TOPPING DX1 II fits this type of user?

3. TOPPING DX5 II is Built for Headphone Variety and Higher-Power Applications
One of the most obvious differences is the headphone amplifier section.
The TOPPING DX5 II provides three headphone outputs:
6.35mm single-ended
4.4mm balanced
4-pin XLR balanced
Its X-Hybrid headphone amplifier uses a fully balanced, four-channel architecture and delivers up to 7600mW × 2 of output power.
This gives the TOPPING DX5 II considerable headroom for a wide range of headphones, from sensitive IEMs to more demanding headphones.
The TOPPING DX1 II also uses a four-channel fully balanced headphone amplifier and provides both 3.5mm and 4.4mm outputs. Its output reaches up to 1000mW × 2 at 32Ω, with two gain settings.
For many everyday headphones and IEMs, this is already more than enough.
In simple terms:
DX1 II: compact and powerful enough for a wide range of headphones.
DX5 II: designed for users who want substantially more amplifier headroom and more headphone connection options.
You don't need the higher output power simply because a device has it. The choice depends on your headphones and how you plan to use your system.
4. Both Support 10-Band PEQ, but the Applications Are Different
A major feature shared by both products is 10-band parametric EQ (PEQ).
You can adjust frequency, gain, and bandwidth to fine-tune the sound.
This can be useful for:
Headphone frequency response adjustment
Personal sound preferences
Speaker tuning
Gaming audio
Target curve matching
Compensating for the characteristics of different headphones
DX5 II: PEQ for a More Complete Desktop Audio System
The TOPPING DX5 II supports independent PEQ configurations for different outputs, allowing users to customize headphone and speaker playback separately.
This makes it particularly useful if you regularly switch between headphones and speakers.
For example:
Profile 1: HD650 headphone tuning
Profile 2: IEM tuning
Profile 3: Active speaker tuning
You can save multiple profiles and switch between them according to your listening setup.
DX1 II: PEQ as a DSP Tool
The DX1 II takes PEQ in another direction.
Its optical input and output allow it to function as a dedicated DSP processor.
For example:
Game Console → Optical → DX1 II → Optical → DAC
The TOPPING DX1 II can process the signal with its 10-band PEQ before sending it to another DAC.
This means you don't necessarily need to replace your existing DAC to gain access to PEQ.
That makes the DX1 II particularly interesting for users who already have an audio system and want to add DSP processing.
5. TOPPING DX1 II Has an Important Advantage for Gaming
The DX1 II was designed with gaming applications in mind.
Its 10-band PEQ can be used to create customized gaming profiles.
For example, players can adjust specific frequency ranges to make certain details such as footsteps and positional cues easier to distinguish.
Multiple profiles can also be saved for different games or listening preferences.
The DX1 II additionally supports compatible TRRS gaming headsets through its 3.5mm connection, allowing headphone audio and microphone communication through the same headset.
It also supports UAC 1.0 mode for devices such as the PlayStation 5 and Nintendo Switch.
A typical gaming setup:
Gaming PC / PS5 / Switch → DX1 II → Gaming Headset
For gamers who want a compact DAC with headphone amplification and customizable DSP, this is one of the DX1 II's strongest use cases.
6. TOPPING DX5 II Offers More Connectivity and System Integration
If you want more than a simple headphone setup, the DX5 II has a broader feature set.
It supports Bluetooth 5.1 through the QCC5125 platform, including:
LDAC/aptX Adaptive/aptX HD/aptX/AAC/SBC
This allows wireless sources such as smartphones and tablets to be integrated into the same desktop audio system.
The DX5 II also includes 12V Trigger input and output.
This can be useful in systems where multiple components need to power on and off together.
Combined with its preamp function, multiple headphone outputs, display, remote control, and extensive digital connectivity, the DX5 II is designed to work as a central desktop audio hub rather than simply a USB headphone DAC.
7. TOPPING DX1 II Is Easier to Integrate Into a Minimal Setup
The DX1 II takes the opposite approach.
It receives both audio data and power through USB-C, making it a simple plug-and-play solution for computers and compatible devices.
A basic setup can be as simple as:
Laptop → USB-C → DX1 II → Headphones
There is no need to build a larger desktop audio system around it.
This makes the DX1 II particularly suitable for:
Small desks
Gaming setups
Laptop users
Students and home offices
Desktop headphone listening
Users who already own a DAC
Users who want to add PEQ without replacing their existing equipment
