WiiM Vibelink Amp High-Power Stereo Integrated Amplifier Pure Power. Zero Distractions. The WiiM Vibelink Amp is a dedicated high-performance amplifier designed for audiophiles who already own a streamer. Stripping away the wireless modules, it focuses 100% of its resources on audio quality and amplification. With 100W per channel (8Ω) and a pure analog circuit, it is the ultimate power upgrade for your WiiM Ultra or legacy audio sources. Audiophile-Grade Amplification TI TPA3255 with PFFB Technology At its core, the Vibelink Amp utilizes the premium TI TPA3255 Class-D amplifier chip, enhanced with Post-Filter Feedback (PFFB) technology. This load-independent architecture ensures consistent, ultra-low distortion sound regardless of your speaker's impedance, delivering 100W x2 @ 8Ω or a massive 200W x2 @ 4Ω. Pure Analog Path (No ADC) Unlike the standard WiiM Amp which digitizes analog inputs, the Vibelink Amp features a pure analog RCA signal path. Your vinyl turntable or high-end CD player's signal remains analog from input to amplification, preserving the original warmth and texture without unnecessary conversion. Flagship Digital Decoding ESS Sabre ES9039Q2M DAC For digital sources (TVs, Transports), the Vibelink Amp employs the latest generation ESS ES9039Q2M flagship DAC. It supports up to 24-bit/192kHz decoding via its Optical and Coaxial inputs, delivering industry-leading dynamic range (120dB) and transparency. Smart System Integration Built to work in harmony. The Vibelink Amp features a 12V Trigger Input and Auto-Standby. When you turn on your connected WiiM streamer (like the WiiM Ultra), the Vibelink Amp wakes up instantly. When the music stops, it goes to sleep, saving energy without you lifting a finger.

The "Ultra" Partner: Designed aesthetically and functionally to stack with the WiiM Ultra. Use the Ultra for streaming, HDMI ARC, and Subwoofer control, and let the Vibelink provide the raw muscle. Vinyl Purist Friendly: The only WiiM amp that doesn't convert your record player's sound to digital. It keeps it analog all the way to the speaker terminals. More Power, Less Noise: With 200W @ 4Ω, it drives demanding floor-standing speakers that the standard WiiM Amp (60W) struggles with. Premium Build: Features the same anodized aluminum unibody as the WiiM Ultra, with an upgraded internal copper heat pipe cooling system for silent operation. Frequently Asked Questions Does it have Wi-Fi or Bluetooth? No. The Vibelink Amp is a pure integrated amplifier. It does not stream music on its own. It is designed to be connected to a streamer (like WiiM Ultra, Mini, or Pro Plus) or other audio sources. Can I connect a subwoofer? The Vibelink Amp itself does not have a subwoofer output. However, if you use it with a WiiM Ultra or WiiM Pro Plus, you can connect your subwoofer to the streamer's sub-out, and the Vibelink Amp will handle the main speakers. Is it better than the WiiM Amp Pro? It is different. The WiiM Amp Pro is an "All-in-One" (Streamer + Amp). The Vibelink Amp is just an Amp, but it has more power (100W vs 60W) and a pure analog path. Choose Vibelink if you already have a streamer or need more power. Complete the Flagship Stack: Pair the Vibelink Amp with the WiiM Ultra Streamer for a complete system with touchscreen control and subwoofer management. The Audiophile Value Combo: Connect the WiiM Pro Plus to the Vibelink's RCA inputs to utilize its pure analog signal path
