WiiM Vibelink Amp Stereo Power Amplifier
The WiiM Vibelink Amp is a compact two-channel Class-D power amplifier designed to partner with streaming sources or existing WiiM streamers, making it well suited to both modern multi-room systems and more traditional hi-fi setups. With analogue and digital inputs on board, it suits listeners who want a dedicated, high-performance amplification stage without the complexity of a built-in streamer.
Why we like it
- 100W per channel into 8 ohms, rising to 200W per channel into 4 ohms, for confident, room-filling sound
- Built-in ESS ES9039Q2M DAC paired with a TI TPA3255 amplifier chip for clean, detailed reproduction
- Supports high-resolution 192kHz/24-bit playback via optical and coaxial digital inputs
- Anti-pop noise design prevents audible clicks or pops when switching inputs or changing sample rates
- 12V trigger input and auto standby mode allow convenient, energy-efficient integration into a wider system
Installation notes
This is a pure power amplifier rather than a streamer, so it requires a separate source such as a WiiM streamer, a digital transport, or an analogue component connected via RCA. It pairs effortlessly with WiiM streamers including the Ultra, Pro Plus, Pro, and Mini, and shares a compact footprint with the Ultra for easy stacking. Speaker outputs are via stereo banana plugs, with a terminating impedance range of 2.67 to 8 ohms, so most 4 to 8 ohm ceiling, in-wall, or standmount speakers can be driven. The 12V trigger input allows the amplifier to power on and off automatically alongside compatible source equipment, while auto standby conserves power after a period of inactivity.
