What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
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.

Our summary
Product Strengths
- Equipped with a desktop-grade ES9038Pro DAC chip
- Balanced sound with good high-frequency extension and sufficient low-frequency response, voices are quite natural, orchestras sound full yet detailed, and spatial information is excellent with a rather deep and wide stereo image and excellent focusing
- Can be used as a network player, DAC, or headphone amplifier, offering flexibility in different setups
- Versatile connectivity with digital outputs (TOSlink, SPDIF, I²S, AES-EBU) and inputs (USB B), as well as analog outputs (RCA, XLR), microSD card slot, and network capabilities (Wifi, Ethernet)
Product Considerations
- Input options are limited as a DAC, restricted to USB B
- The display's dimming feature might be inconvenient, requiring a power cycle to revert to 'always on'
- Standard letters with special marks from some European languages are not reproduced, replaced with Chinese glyphs instead
- Streaming service integration is limited (no direct Spotify, Qobuz, Tidal), requiring workarounds via Airplay or Bluetooth
- Navigating playback modes like repeat/random can be cumbersome, requiring multiple menu layers via remote
Comparisons (according to reviewers)
- Vs Soundaware D100Pro—the DP5 has a bigger display
Takeaway: The SMSL DP5 is a feature-rich device that combines network playback and DAC capabilities, delivering good sound quality and versatility for various audio setups. It is a well-built unit that offers upgrade options for those looking to improve their DAC in the future.

Reviews
Audiolab is a hifi brand known for its unique streaming platform from Pixel Magic, which enables over-the-air updates and wide audio format compatibility including DSD. Their amplifiers and components feature distinctive capabilities like HDMI ARC inputs, user-selectable digital filters for sound customization, and advanced filtering technology in their pre/power amps.
Expand Details
Our summary
Product Strengths
- Very musical with good bass and rhythm, it sounds sweet and immersive
- Delivers wonderful sound with high-res tracks from Amazon Music HD and Qobuz
- Offers great value for money, delivering in pretty much every important area at its price point
Product Considerations
- The DTS Play-Fi app can be frustrating to work with, and is not intuitive
- Lacks gapless playback which means it will not play any album from a music library without unwanted pauses
- Using the DTS Play-Fi app is a chore
- Performance is affected by data rate and transmission conditions through the phone and its wi-fi link—a source of both complexity and variability
Comparisons (according to reviewers)
- Vs Bluesound Node 2i: The Audiolab 6000N Play proves the more insightful and involving listen with greater clarity, openness and a down-the-middle tonal balance, though the Node 2i knits music strands together more tightly and has more warmth
Takeaway: The Audiolab 6000N Play is a great affordable way to add streaming to any hifi system without losing sound quality. It has a neutral look and is a competent sounding streamer for the money.

Comparisons (according to reviewers)
- Vs Cambridge Audio MX-N10—the NP5 has more mature, defined, transparent, and natural sounds, while the MX-N10 delivers more punch to the sound
- Vs Bluesound Node—the NP5 offers better levels of clarity, soundstage, and definition, but the Bluesound Node is more feature-rich
- Vs WiiM Pro—the NP5 has a bigger, more open, and more dynamic soundstage

Reviews
Holo Audio has established itself as a leader in the modern mid-level R-2R DAC movement, focusing on creating DACs with a natural, rich sound that emphasizes musicality over pure detail. Like Denafrips, Holo Audio is known for precise engineering, low noise levels, and exceptional value, offering performance that rivals far more expensive competitors. With a similar approach and price range, Holo Audio is frequently mentioned alongside Denafrips as a top choice for audiophiles seeking high-quality sound without the high-end price tag.
Expand Details
Product Strengths
- High-quality build, feels substantial and well-made due to the aluminum casing and hefty weight
- Offers versatility by functioning as both a streamer and a DDC (digital-to-digital converter)
- Delivers very low jitter and noise
- Improves the sound quality, details, and soundstage compared to using a computer directly as a source
- Provides various connectivity options, including I2S, AES, SPDIF (BNC, Coax, Optical), and USB
Product Considerations
- Switching between DDC and streamer modes requires physically disconnecting the USB-B cable and power cycling the device, which is not ideal
- Initial setup and software flashing might be necessary for some users to ensure optimal performance
- Only connects via Ethernet, as it does not have Wi-Fi
- Some users have found that a power conditioner is necessary to get the best sound
Comparisons (according to reviewers)
- The Red provides a wider and deeper soundstage, as well as a lower noise floor, compared to the Raspberry Pi
- Favored for its performance as a DDC and streamer combo, as well as for build quality, the Red is better than the iFi Zen Stream and iFi Neo Stream, the latter of which is considered a good all-in-one solution with a built-in DAC
- Sounds night and day better, the Metrum Amber sounds more distant, fuzzy, and not as crisp
Takeaway: The Hello Audio Red is a versatile device that can function as a streamer and DDC. It offers a clean and detailed sound, making it a worthwhile addition to a high-quality audio setup.
