WiiM Vibelink is a new integrated stereo amplifier developed by Linkplay Technology Inc. This device stands out from other WiiM products in that it does not include built-in streaming, but focuses solely on high-quality audio amplification. Its compact size, powerful Class D circuit with PFFB technology, and support for digital and analog sources make it a versatile solution for various audio systems.
The amplifier is based on a Class D circuit with Advanced Post-Filter Feedback (PFFB) technology, which reduces distortion and provides natural sound. The design uses Texas Instruments components, including TI TPA3255 amplifiers and TI OPA1612 operational amplifiers. Heat dissipation is provided by a copper heat pipe, a massive aluminum radiator, and a Precision PID Control system, which monitors the operating parameters of the device in real time.
The WiiM Vibelink Amp output power is 2 x 100 W at 8 ohms and 2 x 200 W at 4 ohms, making it suitable for use with a variety of speaker systems. An RCA analog input and two digital inputs – coaxial and optical S/PDIF – are provided for connecting sources. The built-in ESS 9038Q2M digital-to-analog converter supports resolutions up to 24 bits / 192 kHz and uses the Adaptive Sample Rate & Bit Depth system for optimal signal processing.
The amplifier’s body is made of aluminum and is available in silver and space gray colors. The dimensions of the device are 200 × 212.5 × 63 mm, and the weight is 2.05 kg. Gold-plated terminals are used to connect the speakers, and an additional 12V trigger allows you to integrate the device into complex audio systems.
