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.

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 Audiolab M-DAC Nano, the Go Blu offers a wider soundstage, better separation, and dynamic sensitivity, though the M-DAC Nano is fractionally punchier in the bass
- Compared to the AudioQuest DragonFly Cobalt, the Go Blu is a wireless proposition, unlike the DragonFly Cobalt, which is a USB plug-in DAC
- Compared to the FiiO Q3, the iFi GO blu highs are a bit too brilliant, but everything else sounded quite impressive
- Compared to the NuPrime Hi-mDAC, the iFi GO Blu mids sound a lot like it, even if voices are slightly less natural
- Compared to the Hidizs S9 Pro and Aune BU2, the GO Blu provides a relaxed sound and has better build and functionality compared to the Hidizs S9 Pro, but is better when using bluetooth compared to Aune BU2, however when competing on wired terms, the Aune is clearer
Takeaway: The iFi GO blu is a tiny but mighty device that delivers impressive sound and versatility—improving the wireless music experience. It is easy to use and has some cool features, making it a good pick for anyone looking for a portable upgrade for their headphones.

- Vs Schiit Hel, the Schiit Gunner has more power output, portability, audio shaping controls, negative gain mode for IEMs, and a more muted aesthetic
- Vs Schiit Magni Unity, the Schiit Gunner is not quite up to the Magni Unity for music listening, which puts out more power and has a thicker sound
- Vs Schiit Fula, the Fula is more portable, has a 3.5mm out, optical in, mic in, and a headphone out with a knob
Takeaway: The Schiit Gunner is a good amp/DAC that is great for gaming and listening to music, especially if a microphone input is needed. The portability and extra controls make it a versatile choice.
