This review dives deep into the Topping DX5 II DAC/headphone amplifier, examining its strengths and weaknesses in detail. We explore its build quality, starting with the surprisingly robust packaging despite external box damage, and then delve into the premium feel of the aluminum chassis and full-color display, despite noting some design flaws like fingerprint susceptibility and inadequate rubber feet. Our assessment covers connectivity options, highlighting both the comprehensive selection and a notable omission – the lack of dual-mode XLR connectors. We compare its performance against other devices in our arsenal, including the Luxman X9 and the reviewer’s previous Topping gear.Furthermore, the review analyzes the DX5 II's sound signature, focusing on a perceived upper-midrange emphasis that may not appeal to all listeners. Significant attention is given to ongoing firmware issues, specifically concerning the parametric EQ, and the impact these have on the overall user experience. Finally, we address the user interface, noting both its intuitive aspects and areas for improvement, including display stutters and the lack of automatic headphone mode switching. Ultimately, we provide a balanced perspective, weighing the DX5 II's features and shortcomings to help potential buyers determine if it’s the right choice for them.

Unboxing and Initial Impressions
The Topping DX5 II arrived in surprisingly good condition, considering some shipping mishaps. The unit was well-protected with foam padding inside the box, ensuring no damage during transit. However, the box itself showed signs of wear and tear, which could be a concern for resale value.
The aluminum chassis and home button felt premium, adding to the overall positive initial impression. The full-color display was also visually appealing, although some minor quirks with its functionality would later become apparent.
Background and Previous Topping Experiences
My prior experience with Topping gear includes the DX3 Pro Plus and the MX3S. While both delivered exceptional sound, the DX3 Pro Plus unfortunately malfunctioned after only a week. This led to a refund and the purchase of the MX3S, which served me well for years.
The MX3S's incompatibility with my planar magnetic headphones (Sundara and Anand Nano) prompted my search for a new DAC/headphone amp. The protection mode frequently activated when using these headphones with the MX3S.
Connectivity and Physical Features
The DX5 II offers a comprehensive range of connections, including IEC power connector, 12V trigger, coaxial, optical, USB, Bluetooth antenna, RCA outputs, and XLR outputs. Input jacks are conveniently located on one side, while outputs are on the opposite side for organized cable management.
A notable omission is the lack of Topping PA7-style dual-mode XLR connectors, which would allow for both TRS and XLR connections. This was a slight disappointment, considering the potential compatibility benefits.
Functionality and Usability Issues
The DX5 II lacks the automatic switching to headphone mode when a headphone is plugged in, unlike my older MX3S. This requires manual selection via the menu or remapping the volume button, adding extra steps in the workflow. Similarly, the included remote lacks a battery, a cost-cutting measure that felt unnecessary.
The aluminum chassis is prone to fingerprints and smudges, a design flaw that detracts from the premium feel. The rubber feet are also inadequate, leading to instability on the desktop surface, requiring the purchase of aftermarket rubber feet for improved stability.
Sound Quality and Comparisons
In comparison to the Luxman X9 (used in conjunction with the Topping PA7 power amplifier), the DX5 II presented a different sound signature. While both the X9 and PA7 offer a wide soundstage with detailed imaging, the DX5 II exhibited a slight emphasis on the upper midrange.
This emphasis resulted in a perception of thinness in the overall sound, especially when compared to the X9 and other devices like the Fire K11 R2I and Fire K7. This characteristic, while distinct, may not be appealing to all listeners.
Parametric EQ and Firmware Issues
The DX5 II features a parametric EQ, intended to allow for customization. However, ongoing issues with the PEQ functionality, as discussed on audio forums like Audio Science Review and HeadFi, highlight the need for further firmware updates from Topping.
The reviewer indicates that two firmware updates were released within 24 hours, demonstrating Topping's efforts to address the issues. However, the ultimate impact on sound quality and overall user experience remains uncertain pending a full resolution.
Menu Navigation and Display Quirks
The menu system on the DX5 II is generally responsive and intuitive. The “Menu” button functions as a “Back” button, streamlining navigation. Moreover, the device includes menu position memory, allowing users to easily return to previously accessed settings.
However, the display stutters and animations slow down when adjusting the volume, indicating a potential bug affecting the smoothness of the user interface. While the display itself is sharp and legible, this issue detracts from the overall experience.
Output Settings and Volume Control
The DX5 II offers various output options, including line out (single-ended and balanced) and headphone output. While it does not automatically switch between outputs upon connecting headphones, the reviewer suggests utilizing the mode dial to cycle through options efficiently.
DAC mode, which provides fixed-volume line outputs, should be avoided due to potential issues with volume memory across outputs. The reviewer recommends leaving the unit in preamp mode for more reliable volume control and memory functionality.
Overall Conclusion and Recommendation
The Topping DX5 II, while offering several features and a good overall package, has a few significant drawbacks. The upper midrange emphasis might be a preference for some but could be perceived as harshness by others. The numerous ongoing firmware issues concerning the parametric EQ also remain a significant concern.
Considering the price point, it’s a decent option but might be surpassed by other DACs in terms of pure sound quality. The build quality and user interface quirks also present some frustrations. Whether or not this is a good choice for any individual will highly depend on their specific needs and preferences.
