Product Strengths
- Tidal, Roon, Deezer, Spotify, TuneIn, and Qobuz compatibility via the AIO App
- Clean Optical Signal, and even a 3.5mm output
- Excellent build quality, as it is an all-around metallic device

Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Triangle leverages its Esprit Ez series paper cone technology in its more affordable Borea line, allowing for stunning realism and tonality in the midrange at an accessible price point.
- Triangle speakers leverage their Efficient Flow System (EFS) tweeter design, pairing a silk dome with a phase plug to provide a wide sound dispersion and airy, delicate high frequencies.
- Triangle's Borea line incorporates their Driver Vibration Absorption System (DVAS), which braces the drive units and uses high-density foam to minimize cabinet vibrations and enhance clarity, contributing to the overall sound quality.

- 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
- Vs Naim ND5XS—the NP5 is more detailed, tighter defined, and more precise in terms of placement in the stereo image
- Vs Argon Audio Solo—the NP5 has more resolution and separation, and it projects vocals and soundstage a little bit more viscerally

Our take on the brand
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.

Our take on the brand
This ability to make music more alive, less aggressive and really "warmer". We sought to obtain this sound from current dematerialized sources. After various prototypes, it turned out that using 5703 subminiature tubes was the ideal solution, so we designed a class A tube output stage that brought the "magic" of vinyl.
Achieving this result seemed possible to us by combining several technologies and design. That's what we did! The WTX-StreamTubes is a WiFi or Ethernet network player, it integrates many streaming services like Spotify, Qobuz, Tidal, Deezer, Amazon Music, etc., several thousand local, national and global radio stations via TuneIn or vTuner, playback of your music library stored locally on your computer, smartphones, tablets or network drive (NAS).
The WTX-StreamTubes has a complete connectivity. You can connect our Bluetooth Direct Digital X-FTB01 or X-FTB02 HD dongle to it via its proprietary port.
The Advance PlayStream application for controlling the WTX-StreamTubes is available for free download on the AppStore (iOS) and GooglePlay store (Android). DLNA compatible. With this application, you can control multiple Advance Paris products that have network functionality. You can play the same music in all rooms or different music in each room.
Our summary
Product Strengths
- Unique tube-based output stage using 5703 subminiature tubes delivers analogue warmth
- Comprehensive streaming service support includes Spotify, Qobuz, Tidal, Deezer, Amazon Music, TuneIn, and vTuner radio services
- Robust multiroom capabilities allow streaming different audio sources to multiple rooms simultaneously
- The app is responsive, controls well, and connects directly with Spotify output
- Sound staging seems to open up a little more—expansive sound staging width, which is very common of tube stage preamps or amplifiers
- Bluetooth connectivity requires optional dongles
Product Considerations
- The app structure is the same for the WiiM streamer app, suggesting shared software programming
Comparisons (according to reviewers)
- Compared to the Topping DAC, the WTX-StreamTubes has a higher voltage output
Takeaway: The WTX-StreamTubes offers a unique way to experience digital music with the warmth of tubes and is easy to use with its responsive app and comprehensive streaming support. Its multiroom capabilities and tube sound make it a good option for those wanting to upgrade their streaming setup

Our take on the brand
Product Strengths
- Designed with a focus on playback quality, using a custom computer platform instead of existing solutions
- Has a rich selection of digital outputs, including S/PDIF, AES/EBU, and I²S, and offers clock sync with Denafrips DACs
- Features a powerful quad-core ARM Cortex processor for fast music streaming
Product Considerations
- DLNA streaming is limited to a resolution of 16-bit/44kHz
- The interface and initial installation can be confusing without instructions
- Roon certification is ongoing and not yet completed
Comparisons (according to reviewers)
- Compared to the Eversolo A6 Master Edition, the Arce offers a more analog sound with richer bass, while the Eversolo is more punchy, dynamic, and in-your-face
- Arce seemed equally musical and detailed as the Metrum Ambre, with a high dose of transparency
- Compared to the Meitner MA3 DAC (internal streamer), Arce sounded similar, losing only a little transparency and space after extremely careful listening
- Arce is slightly faster, more open, more detailed, and has a nicer exterior design than the AlloUSBridge
Takeaway: The Arce streamer is an excellent choice if one wants great sound, a nice look, and useful features, especially if Roon is already being used and there is a good DAC with I²S or AES/EBU. It does a great job streaming music and lets one enjoy the sounds hidden in the digital files.

- Some user's found Airplay implementation issues
Comparisons (according to reviewers)
- vs AURALiC Altair G2: The AURALiC sounded more subtly delineated, but the improvement in no way reflected the price difference, showing what fine value the iFi is
- vs Raspberry Pi: Far easier to set up, more user-friendly, and sonically indistinguishable
- vs SOtM SMS200 Neo: The Stream makes the SOtM look decidedly limited in terms of functionality
- vs Bluesound Node: The Bluesound Node offers the addition of a solidly designed and road-tested, closed operating system, analog outputs, and Bluetooth inputs
- vs Pi2Design Pi2AES: A slight advantage to the Zen Stream
Takeaway: The iFi ZEN Stream is a versatile and affordable device for streaming music from various sources to a DAC. It is easy to set up and offers great sound quality, making it a worthwhile addition to any hifi system.
