Over the last couple of weeks we have been stunned by some of the sound qualities coming out of the Advance Paris catalogue. Today, we are reviewing a network streamer in quite a competitive market within the £500 price bracket. With the likes of Bluesound, WiiM or Sonos, amongst others, all fighting for a similar spot…

Whilst many of the functionalities overlap, each streamer has their own unique characteristics and we feel the WTX StreamTubes has a couple of fun tricks up its sleeves. What really sets it apart immediately is its unique implementation of valve technology. In a sea of digital components, this little detail adds a touch of analogue warmth and musicality that’s often missing from other streamers, which often rely purely on solid-state components.

WTX-StreamTubes key features:

The streamer supports a variety of high-resolution formats, including FLAC, WAV, and AAC, amongst others, ensuring that it can handle most demanding digital audio files with ease. It allows for Wifi and Ethernet connections, as well as Bluetooth aptX HD, with the latter requiring the purchase of the optional X-FT Bluetooth receiver.

The WTX-StreamTubes is also equipped with a USB port, allowing for direct playback from external drives, and it integrates smoothly with popular streaming services like Tidal, Qobuz, Spotify, Apple Music, Apple Airplay and TuneIn, amongst many others. Its UPnP compatibility means it can easily slot into an existing home network, allowing you to stream from a NAS or other DLNA-compliant devices without a problem.

Finally, the design feels very solid. Despite it's very small size, it feels well built. The valves are illuminated upon powering up on the front panel, with only a power button plus a source switch between Bluetooth and WiFi streaming. The inclusion of both analogue and digital outputs ensures that it can be paired with a wide range of audio systems, giving you the flexibility to bypass the DAC.

Upon warming up the valves…

When it comes to sound quality, the valves are what make the difference compared to the competition. The implementation of 5703 subminiature valves in the output stage delivers a sound that is both smooth and engaging, with a natural warmth that complements a wide range of musical genres. Whether you're streaming classical, jazz, or modern electronic tracks, this WTX translates the sound with a sense of depth and richness that solid-state streamers sometimes can’t replicate.

The tonality is well-balanced, with a slightly pronounced midrange that brings vocals and instruments to life without overshadowing the other frequencies. The bass is tight and controlled, offering enough punch to satisfy most listeners, while the treble is detailed but not harsh, maintaining a smoothness that is easy on the ears even during extended listening sessions. It’s worth mentioning that the unit needs good running in, as it did not sound this neat right out of the box, so a little patience is needed for the components to really click, with the bass tightening up after several listening sessions.

This streamer also has a nice way of handling dynamics. Quiet passages are rendered with delicacy, while louder sections are delivered with a good sense of authority. The soundstage is impressively wide for a streamer in this price range, creating an immersive listening experience that allows you to pinpoint the placement of instruments and voices within the mix. Overall it is a sound that prioritises the emotion and engaging aspects of music over analytical precision.

User Interface

With the sound quality being on par, if not better in some aspects, compared with the top rated streamers in this range, it is equally important to discuss the user interface and the functionality and intuitiveness of the app.

The Advance PlayStream app, available for both iOS and Android, utilises the same interface as WiiM Home, so those familiar with the layout will have no trouble navigating around it. In fact, the StreamTubes can be controlled with the WiiM App without any noticeable drawbacks.

As you can see above, the Advanced PlayStream interface is clean and easy to navigate, whereas some third party control apps don’t have this intuitive and appealing layout.

Advance Paris Vs…

In comparison to its rivals, the Advance Paris WTX-StreamTubes carves out a unique niche. The Bluesound Node, for instance, is widely praised for its excellent DAC and robust ecosystem, but it lacks the distinctive warmth provided by the WTX-StreamTubes’ valve output stage. The Bluesound Node might offer a more clinical, accurate sound, which some might prefer, but for those who enjoy a touch of analogue warmth, the WTX-StreamTubes holds a clear advantage.

When compared to the WiiM Ultra or Pro+, the WTX-StreamTubes offers a more refined listening experience. While the WiiM models are excellent for those who want a straightforward, no-frills streamer with decent support and wide format compatibility, they don’t quite match the musicality and tonal richness of the WTX-StreamTubes. The WiiM Pro+ does offer a great value proposition with its extensive feature set, whereas the WTX-StreamTubes feels like a musical instrument in its own right.

In conclusion, the Advance Paris WTX-StreamTubes is a standout option in the crowded £500 streamer market, especially for those who value sound quality and a touch of audiophile nostalgia. Its use of valve technology offers a unique, warm, and rich sound that is rare to find in streamers at this price point. It delivers an engaging and musical performance that is sure to please those who prioritise audio quality above all else.
