What reviewers think

Magazine reviewers and YouTubers have tried this product—so we've summarized their strongest opinions below.

How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we  discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

Compared to their other products

Advance Paris

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.

Advance Paris is known for integrating tube preamps with solid-state amplification, delivering a warm and dynamic sound that rivals more expensive brands like McIntosh, while offering rare features like HDMI ARC connectivity in their stereo amplifiers. Their products stand out with illuminated VU meters and dual-mono designs using separate toroidal transformers for each channel, while providing high-end features like built-in DACs and phono stages at mid-range prices.

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 Summary

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.
