WiiM Amp Ultra Wireless Audio Streaming Amplifier – Space Grey

WiiM Amp Ultra Streaming Amplifier Delivers Precision Audio Performance

WiiM Amp Ultra Wireless Audio Streaming Amplifier is a space-saving, high-performance amplifier engineered for immersive listening in premium home audio and theatre environments. This compact powerhouse drives 100W per channel at 8Ω and doubles to 200W at 4Ω, empowering bookshelf, floorstanding, and in-wall speakers with startling clarity and dynamic range.

Every design choice in the WiiM Amp Ultra (SKU: WiiM-AMPULTRA-SG) supports high-fidelity reproduction. A next-gen ESS ES9039Q2M SABRE DAC and dual Texas Instruments TPA3255 Class-D amplifiers deliver ultra-low distortion and high headroom. Six TI OPA1612 op-amps further stabilise and refine the output. Integrated PFFB (Post-Filter Feedback) technology ensures sound integrity across all impedance loads, maintaining accurate reproduction even during complex passages.

WiiM Amp Ultra Features Flagship Internal Architecture

WiiM Amp Ultra Wireless Amplifier is built around reference-grade audio components that support 32-bit/384kHz decoding and transparent, bit-perfect playback up to 192kHz/24-bit. These advanced internals include:

• ESS ES9039Q2M DAC for pristine digital-to-analogue conversion
  
• Dual TI TPA3255 high-efficiency Class-D power stages
  
• Six TI OPA1612 op-amps for detailed signal amplification
  

The amplifier maintains a remarkable THD+N of -106dB with a signal-to-noise ratio of 120dB, delivering audiophile-level sound reproduction with near-zero background noise. These specifications allow the WiiM Amp Ultra streaming amplifier to meet the demands of lossless streaming, vinyl replay, and cinematic surround with equal fidelity.

WiiM Amp Ultra Excels with Advanced Thermal Management

WiiM Amp Ultra streaming amplifier uses intelligent thermal architecture to guarantee reliable operation under continuous, high-power loads. A combination of conductive and passive cooling methods ensures the unit stays within optimal temperature parameters without introducing fan noise:

• A copper heat pipe draws thermal energy directly away from the most heat-sensitive components
  
• A large aluminium heatsink disperses heat across a broad surface for maximum efficiency
  
• Precision PID (Proportional-Integral-Derivative) control continuously monitors and adjusts thermal output in real time
  

This fully passive cooling strategy allows the WiiM Amp Ultra amplifier to remain silent and thermally stable—ideal for high-resolution listening rooms or studio-style monitoring environments.

WiiM Amp Ultra Supports Next-Generation Wireless Streaming

WiiM Amp Ultra amplifier delivers seamless connectivity with Wi-Fi 6E and Bluetooth 5.3 technologies for fast, lossless transmission. Whether you're streaming locally stored FLAC files or listening via a major cloud platform, it ensures ultra-low latency and consistent playback quality.

• Tri-band Wi-Fi 6E allows interference-free multi-room audio
  
• Bluetooth 5.3 with SBC and AAC supports high-quality connections to wireless headphones or source devices
  

Compatible streaming platforms include Spotify, TIDAL, Amazon Music, Qobuz, Deezer, Pandora, TuneIn, and iHeartRadio. The amplifier supports Spotify Connect, Chromecast, TIDAL Connect, Qobuz Connect, and is Roon Ready (certification pending), making it interoperable with virtually every modern streaming ecosystem.

WiiM Amp Ultra Touchscreen Display Enables Effortless Control

WiiM Amp Ultra space grey amplifier features a high-resolution 3.5-inch capacitive touchscreen, glass-covered for durability and elegance. Users can browse albums, control playback, access VU meters, toggle sources, and view queue data—all without needing a phone or tablet.
