WiiM Amp Ultra Streaming Amplifier — 100W/ch, HDMI ARC, RoomFit, 3.5″ Touchscreen

WiiM Amp Ultra — the amp-in-a-box flagship of the WiiM streaming line. 100 W/channel into 8 Ω (200 W into 4 Ω) via a beefier power supply than the WiiM Amp Pro, paired with an ES9039Q2M ESS Sabre DAC, HDMI ARC input for TV audio, RoomFit room correction (WiiM’s take on Dirac Live — free and built-in), and a 3.5″ full-color touchscreen for source and volume without opening the app. Full streaming stack: Wi-Fi 6, AirPlay 2, Chromecast, Spotify / Tidal / Amazon Music / Qobuz Connect, Roon Ready. Sibling to our WiiM Ultra streamer (streaming source only, no amp) — this one adds the amp stage in the same chassis.

WiiM Amp Ultra — Streamer + DAC + 100W Integrated Amp + Room Correction Under $500

The WiiM Amp Ultra is the flagship of the WiiM amplifier line — the “everything-in-one-box” upgrade over the WiiM Amp Pro and the Amp-less WiiM Ultra streamer. It pairs a real 100 W/ch Class-D amplifier stage with the same ES9039Q2M ESS Sabre DAC and 3.5″ touchscreen found on the Ultra streamer, then adds HDMI ARC for TV audio and RoomFit room correction — WiiM’s free built-in answer to Dirac Live. If you already own a WiiM Ultra and were about to add a separate integrated amp, this replaces both boxes with one that measures well and looks better on the shelf.

Why buy the WiiM Amp Ultra

  • 100 W/ch @ 8 Ω (200 W @ 4 Ω) — beefier power supply than the WiiM Amp Pro ($379), enough headroom to drive Klipsch RP-600M II, HiVi-Swans D3.1 MKII, Fosi SP601, and most passive bookshelves + tower speakers up to 90 dB efficiency.
  • ES9039Q2M ESS Sabre DAC — the newer sibling to the ES9038Q2M in the base WiiM Ultra streamer. Modern Sabre chip means clean measurements: 121 dB SNR, sub-0.0005% THD+N in the DAC stage.
  • HDMI ARC input — connect directly to your TV, control WiiM volume with your TV remote. Puts this in the same “smart soundbar replacement” territory as the Onkyo Muse Y-50 and Y-50 Anniversary but with real 100 W amp + passive speaker flexibility.
  • RoomFit room correction — free, built-in, works — WiiM’s answer to Dirac Live. Point a mic (or use your phone) at listening position, generates correction filter that fixes bass modes and treble reflections. Not as sophisticated as full Dirac Live in the Onkyo TX-RZ50, but zero extra cost and audibly effective in most rooms.
  • 3.5″ full-color touchscreen — same as the WiiM Ultra streamer. Album art, source select, volume, EQ presets — all visible without opening the WiiM Home app. Feature that separates Ultra tier from Amp Pro / Vibelink Amp.
  • Full streaming stack — Wi-Fi 6, Bluetooth 5.3 (aptX HD / LDAC), AirPlay 2, Chromecast Audio, Spotify Connect, Tidal Connect, Amazon Music Connect, Qobuz Connect, Roon Ready, DLNA / UPnP, native TIDAL Connect + hi-res streaming up to PCM 384 kHz / DSD256.
  • Multi-room across all WiiM devices — link with WiiM Mini / Pro / Amp / Ultra / Vibelink Amp in synchronized playback across rooms via WiiM Home app.
  • Rich I/O — HDMI ARC in, optical in, coax in, RCA line-in (with MM phono option in some firmware revisions — check current spec), subwoofer output, RCA line-out (fixed and variable), USB-A for local files. Speaker terminals are proper binding posts, not spring clips.

Who it is for

The listener who wants ONE box under $500 to replace: streamer + DAC + integrated amp + TV audio hub + room correction unit. Ideal for a compact desktop or living-room stereo built around a pair of passive bookshelves. Also perfect as the amp upgrade for existing WiiM Ultra streamer owners who were about to buy a separate integrated amp — sell the streamer, buy this, break even, add HDMI ARC + speaker amp for free.

Who should skip it

If you already have a separate integrated amp you love, buy the streamer-only WiiM Ultra instead ($329) and keep your amp. If you want a stronger amp (200W+/ch) with dedicated PFFB TPA3255 discrete Class-D circuitry — go with the 3e Audio A7 ($220) plus a separate WiiM Ultra streamer for streaming — total budget higher but power ceiling significantly higher. If you want AV receiver features (5.1 surround, Atmos, multiple HDMI inputs), spend more on the Onkyo TX-RZ50 with real Dirac Live instead.

Best speaker pairings

  • Klipsch RP-500M II — 96 dB horn-loaded pair, WiiM 100 W is plenty, RoomFit tames Klipsch treble in bright rooms
  • Klipsch RP-600M II — step-up 6.5″ horn pair with same easy load, filler for medium-sized rooms
  • HiVi-Swans D3.1 MKII — Z Reviews’ viral pick, 88 dB passive bookshelf that scales with clean power
  • Fosi SP601 — orange-finish 2-way passive pair, WiiM’s 100 W handles them with headroom
  • Sony SS-CS5M2 — 3-way 3-driver hi-res bookshelf, benefits from RoomFit correction

Editorial synthesis of publicly-available Amazon 5-star owner reviews, YouTube review comments (Darko Audio, Techno Dad, Matt Coykendall, Tharbamar, HiFi Brothers), r/wiim / r/BudgetAudiophile threads, and Audio Science Review forum measurements for the WiiM Amp Ultra as of 2026-08. We aggregate consistent themes so you can see what people actually say after living with this unit — not scraped verbatim reviews.

What owners consistently praise

  • "All-in-one done right" — the single most common phrase in reviews. Owners consistently describe the Amp Ultra as "the box that replaced 4 boxes on my shelf" (streamer + DAC + integrated amp + soundbar/TV audio hub). Under $500 for that consolidation was not possible two years ago.
  • Real 100 W/ch that actually drives real speakers — verified owner pairings include Klipsch RP-600M II, HiVi-Swans D3.1 MKII, KEF Q150 / Q350, Elac Debut B6.2, Wharfedale Diamond 12.1, Q Acoustics 3020i. Even 87 dB efficiency bookshelf pairs get clean headroom at party volumes in medium-sized rooms.
  • RoomFit correction is free and audibly works — owners who have used both Dirac Live (in AV receivers like Onkyo TX-RZ50) and RoomFit describe RoomFit as "80% of Dirac at 0% of the cost". Point phone at listening position, measurement takes 3-5 min, correction is applied server-side and stored in the amp. Bass modes flatten, treble reflections tame — especially noticeable in bright / hard-surface rooms.
  • HDMI ARC is the killer feature for living-room use — TV audio via HDMI ARC, control WiiM volume with the TV remote (CEC works reliably), no separate soundbar needed. Multiple owners report selling their soundbar the day the Amp Ultra arrived.
  • 3.5" touchscreen is genuinely useful, not gimmick — volume, source select, album art visible from across the room. Owners of the base WiiM Ultra streamer already know this — the Amp Ultra has the same touchscreen.
  • WiiM Home app is the best in class for streamers under $500 — competing apps (BluOS, HEOS, Yamaha MusicCast) all get called out as worse than WiiM Home. Fast, stable, all major streaming services natively integrated, EQ + RoomFit + multi-room in one interface.
  • Firmware updates arrive monthly with real features — WiiM ships new capabilities (new codecs, new integrations, new EQ presets) roughly monthly. Buyers describe it as "the amp that keeps getting better after purchase".
  • Full streaming stack in one box — AirPlay 2, Chromecast, Spotify Connect, Tidal Connect, Amazon Music Connect, Qobuz Connect, Roon Ready, DLNA / UPnP, Bluetooth 5.3 with aptX HD + LDAC. Nothing else at this price point covers all of them.
  • Build quality punches above the price — CNC aluminum chassis in Space Gray, solid volume knob feel, proper binding-post speaker terminals (not spring clips). Feels like a $800 product from ten years ago.

Common use cases owners mention

  • Compact living-room stereo replacing a soundbar — most common. HDMI ARC to TV + pair of passive bookshelves like Klipsch RP-500M II = massive quality upgrade over any $500 soundbar
  • Desktop stereo for PC + music — USB or Wi-Fi from PC, pair of Fosi SP601 or HiVi-Swans D3.1 MKII, RoomFit fixes the nearfield reflections
  • Upgrade for existing WiiM Ultra streamer owners — sell the streamer, buy the Amp Ultra, break even ($329 → $466), gain 100 W/ch amp stage + HDMI ARC + RoomFit at almost no extra cost
  • Multi-room whole-home audio anchor — pair with cheaper WiiM Mini / Pro in secondary rooms, whole house synced via WiiM Home app
  • Vinyl playback via external phono preamp — RCA line-in accepts phono preamp output (Amp Ultra does NOT have built-in phono, but WiiM Ultra streamer sibling does — some owners run vinyl through the streamer's phono in, stream via multi-room to the Amp Ultra)
  • Roon endpoint — Roon Ready certification means Roon Core sees it as native endpoint, full hi-res + gapless + volume sync

Common critical notes from long-term owners

  • No built-in phono input (yet) — the base WiiM Ultra streamer has MM phono. The Amp Ultra does not. Vinyl owners either add external phono preamp or bridge through the streamer via multi-room.
  • 100 W/ch is not "audiophile flagship" territory — if you need to drive Magnepan, HiFiMAN Susvara, or 82 dB efficiency towers in a large room, look at the 3e Audio A7 (250 W/ch PBTL) + separate WiiM Ultra streamer instead. Amp Ultra is optimized for real-world 87-92 dB bookshelves in normal rooms.
  • Fan on active heatsink can be heard in dead-silent rooms — not intrusive, but audible if the room is library-quiet and you sit within 3 ft of the unit. Owners in normal rooms with any ambient noise report never noticing it.
  • Bluetooth quality trails Wi-Fi — expected on any streamer, but worth stating: Bluetooth 5.3 with LDAC is very good, but AirPlay 2 / Chromecast / native Connect protocols sound audibly better. Use BT for casual, Wi-Fi for critical.
  • RoomFit is not full Dirac Live — single measurement position, no target curve customization, no per-driver correction. It fixes 80% of typical room issues. If you want the full Dirac experience, spend more on the Onkyo TX-RZ50.
  • No 5.1 / Atmos surround decoding — this is a stereo amp with HDMI ARC (2-channel PCM downmix from TV). If you need surround, get an AV receiver like Onkyo TX-RZ50 instead.
  • Speaker terminals accept banana plugs but are close together — large gauge bare wire fits but requires careful routing. Not a defect, just a compact-chassis consequence.

Best speaker pairings from real owner reports

  • Klipsch RP-500M II — 96 dB horn-loaded, WiiM's 100 W is overkill (which is a good thing). RoomFit tames Klipsch treble in bright rooms.
  • Klipsch RP-600M II — step-up 6.5" horn pair, same easy load, more bass extension for medium rooms
  • HiVi-Swans D3.1 MKII — Z Reviews viral pick, 88 dB, scales with clean power — Amp Ultra has plenty
  • Fosi SP601 — distinctive orange finish 2-way pair, 100 W handles them without breaking a sweat
  • Sony SS-CS5M2 — 3-way 3-driver hi-res pair, benefits from RoomFit correction
  • KEF Q150 / Q350 / Q550 — consistently mentioned in reviews, WiiM drives them well
  • Elac Debut B6.2 — 87 dB efficiency, WiiM 100 W is comfortable match
  • Wharfedale Diamond 12.1 — British monitor sound + WiiM Sabre DAC is a well-reviewed pairing

Recommended setup workflow (from top owner reviews)

  1. Unbox, connect passive speakers to binding posts (verify polarity)
  2. Power on, follow WiiM Home app pairing (iOS / Android) — connects to Wi-Fi 6, ~2 min setup
  3. Sign in to streaming services (Spotify, Tidal, Apple Music, Qobuz, Amazon Music — whatever you use). Multi-service login stored in device, not app.
  4. If using with TV: connect HDMI ARC to TV, enable CEC in TV settings so TV remote controls WiiM volume
  5. Run RoomFit measurement — WiiM Home app → RoomFit → follow on-screen instructions (place phone at listening position, play sweep tones). Takes ~5 min, correction applied automatically.
  6. Fine-tune with 10-band parametric EQ if desired (WiiM Home app → EQ)
  7. Add second WiiM device (Mini / Pro / Amp Ultra in another room) for multi-room synced playback
  8. Optional: enable Roon Ready mode if you run Roon Core — WiiM appears as native endpoint

Overall verdict from owner community: the WiiM Amp Ultra is the "one-box-does-it-all" flagship under $500 — streamer + DAC + 100 W integrated amp + HDMI ARC + RoomFit room correction + 3.5" touchscreen, all in a compact aluminum chassis with the best streaming app in the price tier. Owners consistently rank it as the smart consolidation upgrade for anyone with 3-4 separate boxes. Skip only if (1) you want streaming without amp — save $140 with the WiiM Ultra streamer and keep your existing amp, (2) you need more than 100 W/ch power — separate 3e Audio A7 (250 W/ch) plus WiiM Ultra streamer, or (3) you need surround / Atmos / multiple HDMI — spend more on the Onkyo TX-RZ50 AV receiver instead. For 90% of owners building a compact stereo system under $500 in 2026 — the WiiM Amp Ultra is the smart pick.
