The WiiM AMP Ultra is the flagship of the WiiM streaming amplifier range, a compact box that turns a pair of passive speakers into a complete stereo system with music, television and control in one place.
Day to day, a touchscreen on the front shows what is playing and handles playback without reaching for a phone. HDMI ARC brings television sound through the same speakers, so films and music share one familiar setup.
Behind that sits a Class-D output stage with post-filter feedback, giving bookshelf and floorstanding speakers properly controlled power. RoomFit then adjusts the sound to suit the room it actually lives in.
A subwoofer output and support for the major streaming platforms leave space for the system to grow over time without replacing the amplifier at its centre or the speakers it already drives.

In a living room, study or dedicated listening room, the 606 S3 has the presence to make an evening album feel like an event without asking for floorstanding space. It is the larger stand-mount design in the 600 Series and balances room-friendly proportions with confident musical scale.
A Titanium Dome tweeter opens up fine detail in strings, cymbals and ambience, while the Continuum bass and midrange cone keeps voices natural and rhythmically sure. The more acoustically transparent tweeter grille was developed from Signature work, helping the new high-frequency unit communicate cleanly.
Pair it with suitably rigid stands for focused stereo listening, or use it across the front of a compact home cinema. Black, Oak and White choices give the cabinet a calm visual presence, and the revised terminals simplify a neat, reliable amplifier connection.

| ITEM | DESCRIPTION |
| Main Features | |
| Titanium Dome tweeter | The new decoupled driver is voiced for revealing detail without turning bright or tiring over a long listening session. |
| Continuum bass and midrange driver | The composite cone avoids abrupt changes in behaviour, helping voices and instruments sound open and tonally even. |
| Transparent tweeter grille | The fine mesh, derived from Bowers & Wilkins Signature models, allows the tweeter to work with less acoustic obstruction. |
| Flowport cabinet and revised terminals | The vented enclosure supports controlled bass, while the cleaner terminal layout improves the signal path from the amplifier. |
