WiiM left the streaming out of this amplifier on purpose. The Vibelink Amp is a pure two-channel power amplifier, made to sit under a WiiM streamer and turn its output into proper speaker drive. Nothing inside runs an app or needs an account; it takes a signal and powers the speakers.
It slots in as the matching half of a WiiM stack. An Ultra or a Pro Plus feeds it over RCA or optical, the two components stack cleanly on a shelf or in a cabinet, and the system gains genuine amplifier headroom without a second streaming platform appearing in the signal chain.
That separation suits a serious listening room. Upgrades and firmware live in the streamer while the amplifier simply keeps doing its job, and a CD player or a turntable with its own phono stage can join over the line input without ever touching the digital side.

| ITEM | DESCRIPTION |
| Main Features | |
| Load-tolerant output stage | Feedback taken after the output filter keeps distortion low and the sound consistent from one pair of speakers to the next. |
| Digital and analogue sources | Optical and coaxial feeds are converted internally, while the RCA input stays analogue the whole way through. |
| Silent by construction | A copper heat pipe and the unibody aluminium case cool the amplifier passively; there is no fan to hear. |
| Trigger-linked power | A connected streamer can wake the amplifier automatically, and it stands down on its own when the system goes quiet. |
