Our take on the brand
Product Strengths
- Fully balanced technology, with balanced inputs and outputs.
- Delivers powerful amplification, with up to 7.5 watts of power, capable of driving a wide range of headphones, including hard-to-drive models.
- Features a linear power supply with a large transformer and capacitor bank, providing a stable and powerful power source.
- Provides two current modes (50mA and 100mA) to tailor the sound tonality, allowing users to choose between a more forward/analytical sound and a warmer/fuller sound.
- Employs an R2R network for volume control, ensuring channel balance even at low volumes.
Product Considerations
- Runs quite hot due to its Class A amplification, requiring adequate ventilation, with chassis temperatures potentially reaching up to 50 degrees Celsius, and the unit may switch from 100mA to 50mA mode if it overheats.
- High power output might not be ideal for very sensitive IEMs, potentially limiting volume control flexibility.
- The preamplifier output is always active, meaning it doesn't mute when headphones are plugged in, requiring caution to prevent damage.
- The LCD display cannot be dimmed or switched off, and the red color of the 100mA mode may appear washed out.
- Some report volume slots are not regular or have large jumps, and/or that the remote control can be buggy.
Comparisons (according to reviewers)
- Vs. Topping A90 Discrete: The S17 has a richer sound, wider soundstage, and easier dynamics, especially in 100mA mode, placing it in a higher tier.
- Vs. Topping A90D: The S17 Pro is capable of even stronger dynamic swings, with a slightly cleaner and less cluttered soundstage.
- Vs. Violectric V222: The Aune S17 Pro is more 'tubey' and warmer sounding than the V222.
- Vs. HIFIMAN EF600: The Aune S17 has better volume control, higher dynamic range, better driving power, and better resolution.
Takeaway: The Aune S17 Pro is a powerful and versatile headphone amplifier that delivers rich, detailed sound, allowing listeners to experience music in new ways. With its balanced design and flexible current modes, it can enhance a wide range of headphones and audio setups.

Our take on the brand
Our Summary
Product Strengths
- Phenomenal sound quality.
- Very usable and enjoyable interaction due to a physical volume knob.
- Plenty of power for almost everything and can drive just about anything.
- Versatile; it can be used as a desktop all-in-one, a Bluetooth portable DAC/amp, a portable amplifier, and even a DAC for speakers.
Product Considerations
- Susceptible to EMI noises, which can be a deal breaker; static noises, pops, and crackle sounds can occur when a phone is placed directly on top of it.
- Not a completely balanced architecture; the 3.5mm & 4.4mm headphone outputs sound the same.
- Charging port may not indicate charging on anything higher than an 18W charging block, and some chargers may not work.
Comparisons (according to reviewers)
- Vs FIIO BTR-7: Sounds more refined and has more detail and resolution.
- Vs SMSL C200: The C200 sounds significantly warmer with a fuller, juicier bass line and a little bit more airy, while the G5 is more focused on clean and clear edges, tidy, well-focused—and clean.
- Vs SMSL M500 MK2: The M500 MK2 sounds overall better with dynamics at the same level as the G5 and fuller, warmer tonality—and a bigger, more spacious soundstage.
- Vs Moondrop Moonriver 2: The treble is more refined, better details up top, and a sharp edge without being overboard like the Moonriver 2 can.
Takeaway: The G5 is a well-built and versatile portable DAC/amp with a neutral, clean, and dynamic sound. It is great for those looking for an all-in-one solution that can drive almost any headphone or IEM.

- The DO400's case cover is steel, and the rotary knob wobbles
- Some may find its sound signature a bit too linear for some genres
- The remote control is plastic-y
- The speedy nature of the ESC by Silicon might result in a less impressive initial kick in the eardrums via headphones, compared to the XLR and RCA outputs
Comparisons (according to reviewers)
- Compared to the Topping DX7 Pro Plus, the DO400 is more organic and dynamic sounding
- Compared to the Topping DX5, the DO400 offers noticeably better line output
- Compared to the Chord Mojo 2, the Chord Mojo 2 sounds better when used as a DAC, offering better detail retrieval and a richer tone timbre, but the DO400 has more power
