What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Reviews
Aune Audio is a hifi brand known for its unique approach to DAC design, using custom-built clock generators and dual DAC chips to achieve exceptional transparency and natural sound. Their products, from the Yuki DAC to the S17 PRO headphone amplifier with its symmetrical Class A design and Twin JFET, deliver a tube-like sound signature that's easy to drive without high-end amplification.
Expand Details
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.

Released
2022
Topping Audio is a measurement-focused hifi brand that developed its own proprietary PSRM DAC architecture and NFCA amplifier topology to achieve exceptionally low distortion levels. Their products, from the flagship D90 III Discrete DAC to entry-level interfaces like the E2x2, use advanced technologies like custom I/V conversion stages and high-feedback Class B designs to deliver clean, accurate sound reproduction.
Expand Details
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.

- 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
- Compared to the SMSL SU-9, the DO400 sounds slightly brighter and less-smoothed over—there's an analytical quality to the treble end
