WiiM VibeLink Amp Integrated Amplifier, Space Gray

The WiiM VibeLink Amp is an integrated amplifier with an ESS Sabre DAC and three inputs, deliberately built without a network section. This is WiiM's first device with just one job: amplify. Streaming is left to whoever does it better – a WiiM Ultra in front of it, for instance.

Why the WiiM VibeLink Amp?

Because it keeps the jobs cleanly separated. In an all-in-one device, the sensitive network section sits in the same housing as the power stage. The VibeLink skips that and puts the budget into amplification instead: a TPA3255 with PFFB feedback, six OPA1612 op-amps, and an ES9039Q2M converter for the two digital inputs.

Operation is classic – a volume knob, input selection between RCA, optical and coaxial, done. No menu, no app requirement, no firmware roulette before you can listen to music. You can tell from the first turn of the knob that someone thought this through.

What you hear

Through the digital inputs, the VibeLink delivers 100 W at 8 ohms and 200 W at 4 ohms per channel – with dry, controlled bass and a very quiet background. A THD of -105 dB and a 120 dB signal-to-noise ratio are figures you rarely see at this price point.

Important to know: the analog RCA input passes the signal through entirely in the analog domain, without conversion – but power there is 60 W at 8 ohms or 120 W at 4 ohms. If you want the full reserves, go in digitally.

Who is the WiiM VibeLink Amp for?

For anyone who already has a streamer – WiiM, Bluesound or something else – and wants powerful, clean amplification behind it. And for anyone who'd rather build their system in two parts, so each half can be upgraded on its own later.

Straight talk: The VibeLink has no Wi-Fi, no Ethernet and no Bluetooth audio – without a source feeding it, it stays silent. So it needs a streamer, a CD player or another source in front of it. It also lacks a remote, a subwoofer output and a headphone output. And ecoustics found in testing that it runs out of headroom with very demanding speakers – if you own such speakers, talk to us first.

Our verdict

The VibeLink Amp is the most honest device in the WiiM lineup: no feature list to show off, just a power stage that plays well above its price class. Paired with a WiiM Ultra, that adds up to a two-box setup that delivers more sound than any all-in-one at the same price. At HD Zürisee in Wädenswil, this has become one of our favourite recommendations for small budgets with big expectations.

What the press says: "With highly dynamic, low-distortion sound, the Vibelink brings any music to life. The sonic value it delivers for its price is simply sensational." – HIFI.DE, August 2025 (rating 7.9/10)

Frequently asked questions

Can the WiiM VibeLink Amp stream?

No. The VibeLink Amp has neither Wi-Fi nor a network jack, and it doesn't receive Bluetooth audio either. It needs a source in front of it – for example a WiiM Pro Plus or WiiM Ultra via RCA, optical or coaxial. The Bluetooth LE connection to the app is only for setup and firmware updates.

Is the VibeLink Amp a pure power amp?

No. It has a real volume knob and input selection for three sources, so it works as a full integrated amplifier. You don't need a preamp in front of it – just a signal source. That's exactly what makes it the ideal partner for a network player with a fixed output level.

Why does the VibeLink deliver less power at the RCA input?

Because the analog input passes the signal through without conversion, and uses a different gain stage for it: 60 W at 8 ohms instead of 100 W. If you want the full reserves, connect your source optically or coaxially. The analog path still has its fans, though – it stays entirely in the analog domain.

Can I connect headphones or a subwoofer to the VibeLink Amp?

No, neither is provided for: there's no headphone output and no subwoofer output. For a 2.1 system, use a subwoofer with a high-level input or choose a WiiM Amp Ultra, which comes with a sub output. We're happy to show you both routes.

Why buy the WiiM VibeLink Amp at HD Zürisee?

Because an amplifier without streaming only makes sense if the source matches it. We look at what you already have and tell you honestly whether the VibeLink is the right path or whether an all-in-one suits you better. Advice, delivery and support all come from the same place.
