One is a streaming all-in-one and the other is an amplifier. Judge them on how many boxes you want and what you already own, not on the spec sheet alone.
| Area | Better | Why |
|---|
| Power | B | WiiM Vibelink has more power - 100W against 60W into 8 ohms. That is about 2.2dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Room size | depends | We rate WiiM Amp the better fit for desk or near-field listening and a small room, and WiiM Vibelink for a mid-size room, a large room and a very large room. Match the amplifier to the room you actually have, not the one you want. |
| Grip on hard loads | evenly matched | Both behave much the same into 4 ohms - output nearly doubles (120W and 200W). |
| Noise floor | B | WiiM Vibelink is the quieter design on paper - 110dB against 98dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | evenly matched | Both have a DAC on board with much the same capability. |
| Streaming | A | Only WiiM Amp has AirPlay 2, Chromecast, Roon, Spotify and Tidal. |
| Use with a TV | depends | Only WiiM Amp has HDMI ARC, so the television can drive it directly and one remote controls the volume. If the system is for music only, this changes nothing. |
| Room to grow | A | Only WiiM Amp offers preamp outputs and a subwoofer output - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Room correction | A | WiiM Amp has room correction. In an awkward room that does more for the sound than any other difference on this page. |
| Price | evenly matched | Priced within a few per cent of each other. |
| Watts per dollar | B | WiiM Vibelink is the cheaper watt - about $3 per watt against $5. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A WiiM Amp B WiiM Vibelink
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Neither runs away with it - they trade advantages. Let the "depends" rows and the speakers you already own settle it. Start with the room. In a large or open-plan room, or with speakers that are hard to drive - low sensitivity, or an impedance that dips - WiiM Vibelink has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 60 watts is already more than most people ever use, and the extra 40 watts would be headroom you pay for and never hear - we rate WiiM Vibelink poorly for near-field use for exactly that reason. If this sits under a television, WiiM Amp is the one to buy - HDMI ARC means the TV remote controls the volume and there is no second box in the way.
What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
