KGUSS Topping D10s Mini USB DAC ES9038Q2M - High Resolution Desktop

In this review the KGUSS Topping D10s Mini USB DAC is assessed as a compact desktop DAC/decoder aimed at listeners who want clear, low-noise playback from a PC source. The single biggest reason to consider it is its support for very high resolution formats up to PCM 384kHz and DSD256 combined with an ESS ES9038Q2M DAC chip and XMOS XU208 USB interface, which together deliver noticeably cleaner detail and lower distortion than most basic USB audio adapters.

Key Features

• High resolution playback: Supports PCM 16-32bit and sample rates to 384kHz plus DSD64 to DSD256 for native or DoP playback, letting users play studio-quality files without downsampling.
• XMOS USB interface with custom driver: Uses XMOS XU208 and a Thesycon-based customized driver for reliable high-resolution and DSD native compatibility on PC systems.
• ESS DAC core: Employs the ESS ES9038Q2M to achieve very low THD+N and clearer, more refined audio reproduction compared with typical budget DACs.
• Replaceable op amp: Features an OP amp socket so DIY users can swap the OPA2134 for tonal changes and personalization of the analog output stage.
• Automatic power handling: Powers on and off synchronously with the host PC even if the USB port retains standby power, simplifying everyday use.
• Compact form factor: Small desktop footprint makes it easy to add high resolution decoding to a computer audio setup without taking much space.

Who It's For

The D10s is best for desktop audiophiles, music producers and serious listeners who want a straightforward external DAC to extract clearer detail from high-resolution PCM and DSD files. The unit is especially useful for people who play back native DSD or very high sample-rate PCM from a computer and want a low-noise, accurate front end for headphones or a small amplifier.

It is less suitable for users who need an integrated headphone amplifier with very high output power, or those who require wireless streaming or a battery-powered portable DAC. Also, casual listeners who only stream standard-resolution tracks will see less benefit versus a good integrated USB audio interface.

Pros & Cons

Pros

• Very good high-resolution support including DSD256 and PCM up to 384kHz for future-proof playback.
• Low distortion and clean output thanks to the ESS ES9038Q2M DAC core.
• XMOS XU208 and a customized Thesycon driver provide stable PC compatibility for DSD native streams.
• Replaceable OP amp socket allows tonal tweaks for DIYers who want to modify the sound.

Cons

• Does not include a built-in headphone amp with high output power, so very demanding headphones may need a separate amplifier.
• Advanced DSD setup may require driver installation and a configuration guide to enable native playback for some systems.
