Streamer, DAC, television input, and 100-watt power amplifier: the WiiM Amp Ultra does four jobs in a case the size of a hardback, and that is why it is the integrated amplifier we recommend first. Feed it a pair of passive speakers and it plays from Spotify, from a phone over Bluetooth 5.3, and from the TV over HDMI ARC without another box in the chain. For anyone stepping up from a soundbar, that single-box simplicity is worth more than any one specification on the sheet.
The power rating is the one we trust most. WiiM quotes 100 watts per channel into 8 ohms from a pair of TI TPA3255 chips with post-filter feedback, which keeps the output consistent across different speaker loads — the practical result being that 4-ohm bookshelf speakers don't make it sound thin the way cheaper Class D amps do. The whole unit weighs 5.4 pounds and measures roughly 8 by 8 by 3 inches, small enough to sit beside the speakers instead of in a rack.
RoomFit, the built-in calibration, is what justifies buying a streaming amplifier rather than a plain one. It adjusts the output to your room and speakers, which is the difference between a bass boom in a corner and a system you can listen to all evening without fatigue. The 3.5-inch touchscreen handles volume and input switching without a phone, and the app goes deeper when you want it to.
The gaps are Apple-shaped. There is no AirPlay here, so an iPhone streams through the WiiM app or Bluetooth instead, and in a house full of Apple gear that becomes a daily annoyance rather than a footnote. The supplied remote is the least reliable piece in the box. Neither changes how it sounds, and the app covers most of what the handset misses.

The integrated amp we recommend first for most people: 100 watts, HDMI ARC, streaming, and room correction in one small box that makes passive speakers the center of the room.
