Other features

WiiM Vibelink Amp, a powerful integrated amplifier with an ultra-compact design, designed to offer high-fidelity sound quality for any audio system.

Vibelink Amp delivers 67% more power than the WiiM Amp Pro, already in the catalog since last year, and is equipped with a high-resolution ESS ES9038Q2M DAC that supports audio up to 24-bit/192kHz. The Class D amplifier promises to deliver 100W per channel (8Ω) or 200W per channel (4Ω) and integrates several quality components, including four TI OPA1612 operational amplifiers and a TI TPA3255 amplifier chip, in order to guarantee high-fidelity sound with minimal distortion.

It adopts interesting solutions to avoid overheating, including copper heat pipes, a large aluminum heatsink and thermal management software that ensures optimal temperature regulation.

The amplifier is equipped with RCA analog input, digital, optical and coaxial inputs, as well as trigger in for custom applications.

It is an amplifier that integrates a lot of technology starting from the Post-Filter Feedback (PFFB), which minimizes distortion, improves clarity and ensures consistent sound quality on different speaker impedances. Unlike traditional amplifiers that suffer from variations in performance due to load dependence, PFFB dynamically compensates for these inconsistencies, offering according to WiiM a more precise, balanced and natural sound.

An interesting and quality feature is that of the RCA analog input signal, which does not undergo any ADC conversion, unlike many amplifiers that digitize analog signals. This benefits from a direct and unprocessed audio signal path, for a pure and authentic analog experience.

The manufacturer claims a signal-to-noise ratio (SNR) of 120 dB and a THD+N value of -105 dB (0.0005%), while its compact size (200x200x63mm) allows it to be paired perfectly with WiiM streamers, allowing for multi-room audio and a perfect integration for users who want to expand their audio setups.
