WiiM, a name synonymous with high-quality, affordable streaming audio solutions, has unveiled its latest offering: the Vibelink Amp. This isn't your typical all-in-one streamer-amplifier hybrid. Instead, WiiM has focused on delivering a pure, unadulterated amplification experience, packing a punch with 100W per channel into 8 ohms, all within a sleek, compact chassis. At a mere $299 (available on Amazon), the Vibelink Amp challenges the established audio landscape, promising audiophile-grade performance without the exorbitant price tag.

A Departure from the Norm: Pure Amplification Focus

In a market saturated with feature-laden streaming amplifiers, WiiM's decision to release a dedicated, standalone amplifier is a bold move. The Vibelink Amp strips away the streaming functionalities found in its siblings, such as the WiiM Amp and WiiM Amp Pro, focusing solely on delivering exceptional power and sonic clarity. This approach caters to audiophiles who prefer to curate their audio sources and prioritize pure amplification.

Unleashing Power: Class-D Efficiency and Robust Output

At the heart of the Vibelink Amp lies a Class-D amplifier module powered by the Texas Instruments TPA3255 chipset. This technology offers remarkable efficiency, translating to a powerful 100W per channel into 8 ohms and a staggering 200W per channel into 4 ohms. This robust output ensures the Vibelink Amp can drive a wide range of passive speakers, from bookshelf monitors to floor-standing behemoths, with ease.

The DAC and Op-Amp Symphony: Audiophile-Grade Components

WiiM hasn't skimped on the internal components. The Vibelink Amp boasts an ESS ES9038Q2M DAC, a highly regarded chip known for its exceptional dynamic range and low distortion. This DAC supports high-resolution audio up to 192kHz/24-bit, ensuring pristine digital-to-analog conversion. Complementing the DAC are six Texas Instruments OPA1612 op-amps, renowned for their low noise and high bandwidth, contributing to the amp's clean and detailed sound signature. A Texas Instruments PCM9211 digital and analog front end is also present.

Connectivity: Streamlined for Simplicity

The Vibelink Amp's connectivity is straightforward and focused. It features:

• Analog Input: 1 x RCA stereo input for connecting analog sources like turntables or CD players.
• Digital Inputs: 1 x Optical Toslink and 1 x Coaxial input for connecting digital sources like CD transports or network streamers.
• Speaker Outputs: Standard banana plug outputs for secure and reliable speaker connections.

Notably absent are USB inputs, Bluetooth, and Wi-Fi connectivity, reinforcing the amp's focus on pure amplification.

Design and Build: Compact Elegance

The Vibelink Amp's design is minimalist and elegant. It features a compact, unibody aluminum chassis that exudes a premium feel. The brushed aluminum finish and clean lines contribute to a modern aesthetic that complements any audio setup. The amp's dimensions (7.9 x 7.9 x 2.58 inches) make it ideal for tight spaces, fitting seamlessly on shelves or desktops.

Thermal Management: Keeping Things Cool

Given its powerful output, efficient thermal management is crucial. The Vibelink Amp incorporates a sophisticated cooling system, featuring copper heat pipes, a large aluminum heatsink, and a heat-spreading case. This design effectively dissipates heat, ensuring stable performance even during extended listening sessions. A PID-based thermal management software also aids in optimal temperature regulation and prevents overheating.

Anti-Pop Noise Design: Seamless Transitions

WiiM has addressed a common issue with many powered amplifiers: pop noise during input switching or setting adjustments. The Vibelink Amp features an anti-pop noise design, achieved through hardware optimizations like ramping circuits and software sequencing. This ensures seamless transitions between inputs and settings, providing a smooth and uninterrupted listening experience.

Target Audience: The Audiophile Purist

The Vibelink Amp is designed for audiophiles who prioritize sound quality and prefer to curate their audio sources. It's an ideal solution for those who already own a high-quality streamer, such as the WiiM Ultra, or who prefer to use analog sources like turntables or CD players.

Comparisons and Context:

At $299, the Vibelink Amp competes with a range of integrated amplifiers in the entry-level to mid-range market. However, its focus on pure amplification, combined with its high-quality components, sets it apart.

• Compared to the WiiM Amp Pro, the Vibelink foregoes the streaming capabilities for a pure amplifier design, and offers similar high quality components at a lower price.
• Compared to cheaper amplifiers with many inputs, the Vibelink focuses on high quality components and sound reproduction, rather than a plethora of features.
• Compared to other amplifiers in the same price range from other brands, the Vibelink offers a very high power output, and high quality internal components.

The Future of WiiM and the Vibelink's Role

The Vibelink Amp marks a new direction for WiiM, demonstrating its commitment to catering to a wider range of audiophiles. Its focus on pure amplification and high-quality components positions it as a serious contender in the integrated amplifier market. It also hints at future products, such as the teased subwoofer, that will complement the Vibelink and further expand the WiiM ecosystem.

Conclusion: A Game-Changer in Entry-Level Audiophile Amplification

The WiiM Vibelink Amp is a remarkable achievement, delivering exceptional power and sonic clarity at an unprecedented price point. Its focus on pure amplification, combined with its high-quality components and elegant design, makes it a compelling choice for audiophiles seeking a high-performance amplifier without breaking the bank. The Vibelink Amp is a testament to WiiM's commitment to delivering accessible, high-quality audio solutions.
