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
- Compared to the SMSL SU-9, the DO400 sounds slightly brighter and less-smoothed over—there's an analytical quality to the treble end
Takeaway: The SMSL DO400 is a great-sounding all-in-one unit that offers a lot of features for the price. Its noiseless performance with IEMs and ability to drive most headphones make it a worthwhile purchase.

- May not be suitable for larger spaces or for those who prefer listening at higher volumes, especially with speakers that are hard to drive
- Some users might hear a faint whine from the chassis or speaker tweeters, as the amplifier is not completely silent
Comparisons (according to reviewers)
- Vs Arylic B50: The WiiM Amp has a more complete chassis design with an internal power supply, a slicker app, and better overall industrial design, even if they use similar chipsets
- Vs Bluesound PowerNode/Audiolab 6000A Play/7000A: The Bluesound and Audiolab products are better options for larger spaces or higher listening volumes
- Vs Denon AV receiver: The Denon AV receiver does not have the streaming comprehensiveness of the WiiM Amp
- Vs Sonos Amp: The Sonos Amp may sound better, but the WiiM Amp combined with a subwoofer can provide a more complete sound experience for less money
