Advance Paris WTX-700 EVO Bluetooth Receiver

The Advance Paris WTX-700 EVO is a compact Bluetooth receiver with aptX HD and its own D/A converter that plugs directly into an amplifier's RCA inputs.

This makes any existing system wireless – no rewiring, no cable run across the living room. The module measures less than six centimeters, weighs 24 grams, and disappears behind the device instead of taking up space in front of it.

Why the WTX-700 EVO?

Most Bluetooth adapters sound like an afterthought from the bargain bin. Not the WTX-700 EVO: Advance Paris gives it a dedicated converter from Texas Instruments (PCM5102) and aptX HD. Music from your smartphone arrives at the amplifier converted with high resolution and cleanly, not as a compressed makeshift. Bluetooth 5.0 keeps the connection stable, with roughly ten meters of range covering the sofa, the kitchen counter, and everything in between.

What you get

A plug-in module measuring 6 × 1.4 × 5.5 centimeters that goes into a free RCA line input – AUX, CD or Tape, whichever's available. It's powered by a small plug-in power supply that Advance Paris includes – so it's not entirely without an outlet, but it needs no installation at all. Plug in, pair your phone, music plays: internet radio, podcasts, local files, or a streaming service if you use one. A subscription is explicitly not a requirement. And because the connection is simply RCA, the WTX-700 EVO works on any amplifier, not just Advance Paris devices.

Who is the WTX-700 EVO right for?

Plain talk: if you want multiroom, Wi-Fi streaming or app control, you need a real network streamer – the WTX-700 EVO can only do Bluetooth. If you want to control the level at the module itself, you're also out of luck: the output delivers a fixed line level, and your amplifier handles the volume. But for anyone who wants to give their trusted system easy smartphone access, it's the most elegant solution around.

Our verdict

Smallest form factor, biggest gain in convenience: the WTX-700 EVO is the missing link between smartphone and system – and the only Bluetooth receiver you'll never see again once it's installed.

Frequently asked questions

Does the WTX-700 EVO work with any amplifier?

Yes, with any device that has a free RCA line input – regardless of brand. You plug the module into AUX, CD or Tape, connect the included power supply, select the input, and pair your smartphone. An Advance Paris system is explicitly not required. Even amplifiers from the nineties work perfectly fine with it.

Does the WTX-700 EVO need a power supply?

Yes. The WTX-700 EVO is powered by an external plug-in power supply that Advance Paris includes – the RCA plug alone carries no power. So plan for a free outlet near the device. Nothing else needs to be installed or configured, though: plug in, pair, done. The module then stays plugged in permanently.

How good is the sound quality over Bluetooth?

Noticeably better than typical Bluetooth adapters. aptX HD transmits at up to 24 bits and 48 kilohertz, and the dedicated PCM5102 converter handles the analog conversion. Android devices mostly use aptX or aptX HD, iPhones use AAC – both sound clean, though AAC doesn't quite exploit the full resolution.

Can I connect headphones directly to the WTX-700 EVO?

No, the WTX-700 EVO has no headphone output. It passes the signal exclusively via the RCA stereo output at a fixed line level – volume and headphones are handled by the amplifier behind it. If you want to listen wirelessly on headphones, you'll need a Bluetooth transmitter or an amplifier with transmit capability instead.

Why buy the WTX-700 EVO at HD Zürisee?
