The WiiM Ultra is a network streamer and preamplifier built to sit at the centre of a hi-fi system, with a touchscreen front panel that shows what is playing at a glance.
Its range of connections is the real draw. A phono input welcomes a turntable, HDMI ARC brings in the television, and line, optical and USB sources all share one point of control for the whole system.
An ESS converter handles digital conversion, and RoomFit adjusts the sound to the room, so the amplifier and speakers downstream receive a clean, considered signal whether the source is a stream, a record or the television.
Line, subwoofer and digital outputs keep the streamer open to whichever amplifier it partners, while a trigger output lets connected components follow it on and off.

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. |
