TOPPING DX5 II Hi-Res DAC & Headphone Amp Combo, Dual ES9039Q2M, LDAC Bluetooth 5.1 Review (2026)

Who the DX5 II is built for

This suits someone assembling a serious desktop headphone rig who wants a single unit handling digital-to-analog conversion, headphone amplification, and Bluetooth input without stacking three separate boxes. The balanced 4.4mm and 4-pin XLR outputs alongside a standard 6.35mm jack mean it can drive a wide range of headphones, from efficient IEMs to power-hungry planar models, without needing a separate amp. Its preamp mode, which lets you adjust output volume and feed a power amp or active speakers directly, also makes it useful in a modest turntable-adjacent system built around digital sources and streaming rather than phono playback. It is overkill for someone who just wants basic USB DAC functionality for a laptop and a pair of cheap headphones.

What is under the hood

The DX5 II uses dual ES9039Q2M DAC chips supporting PCM up to 768kHz/32-bit and DSD512, paired with an X-Hybrid headphone amplifier built on a triple-stage hybrid design that TOPPING rates at 133dB SNR and dynamic range. Balanced headphone output reaches 7600mW per channel into 16 ohms, scaling down through higher-impedance loads, with a claimed noise floor of about 1.8 microvolts RMS. Bluetooth 5.1 runs through a QCC5125 chip supporting LDAC, aptX Adaptive, aptX HD, AAC, and SBC, and a 10-band parametric EQ with desktop software lets you reshape the sound signature. A 2.0 inch color screen with a pressable knob controls preamp, headphone amp, and Bluetooth DAC modes, and the unit supports 12V trigger in and out for integration with other gear.

Setting it up and living with it

Setup is plug-and-play across Windows, Mac, Linux, iOS, and Android over USB, with coaxial and optical SPDIF inputs available for other digital sources. An independent review of the unit described the stock tuning as clean, balanced, and neutral with improved dynamics over the earlier DX5, though the bass was called clinical and a bit lean out of the box, a gap the 10-band PEQ can help close for listeners who want more warmth. The same review praised the compact aluminum chassis but noted a small seam between the top and front panels that tends to collect dust. Day to day, the preamp mode with volume memory makes it easy to leave connected directly to active speakers or a power amp without a separate preamplifier in the chain.

How it compares with other headphone amps

In the headphone-amps ranking here, the DX5 II sits at the top of an eight-unit field, ahead of the FiiO K7 and K5 Pro and well ahead of budget options like the AIYIMA DAC-A2 and Fosi Audio Q4. Its dual DAC chip design and balanced 4-pin XLR output give it an edge in raw specifications over the FiiO models, which stick to single DAC chips and 4.4mm balanced output without a full XLR option. Against the Fosi Audio K7, which shares similar power output, the DX5 II's 10-band PEQ and Aurora color screen add a level of tuning and control that simpler competitors in this list do not offer.

Bottom line

Choose the TOPPING DX5 II if you want a single balanced DAC and headphone amp that also handles high-quality Bluetooth streaming and lets you reshape the sound with onboard PEQ. It earns a strong score here for its feature set and build, with the main trade-off being a naturally lean bass response that some listeners will want to correct through the EQ rather than accept as-is. The premium price and deep menu system make it more than a casual listener needs; if you just want a simple DAC and amp without balanced outputs or PEQ tuning, a simpler unit will save money without losing much day-to-day usability.
