BEL CANTO EVO 2i

An integrated amplifier that seamlessly combines aesthetic refinement and technological innovation, embodying the design philosophy of the American manufacturer. Delivering 120 watts per channel into 8 ohms and 200 watts into 4 ohms, this amplifier utilizes Tripath’s Class-T digital amplification technology, a solution that ensures over 90% efficiency while significantly reducing thermal dissipation compared to traditional amplifiers.

The eVo2i’s amplification module employs two N-channel MOSFET switches between the power rails, a hallmark of switching amplifiers. However, unlike conventional Class-D implementations, Bel Canto’s technology eliminates common drawbacks such as high switching noise and frequency response variations depending on the load. This is achieved through advanced noise modeling algorithms that effectively minimize these trade-offs.

The preamplifier section has been meticulously designed to ensure low noise and signal integrity. For volume control, Bel Canto has opted for a combination of a stepped analog attenuator and a digital microcontroller, providing a broad 100 dB adjustment range in precise 0.5 dB increments while keeping the signal path as short as possible.

The rear panel offers comprehensive connectivity, featuring five line inputs, including a pair of balanced XLR inputs, three RCA inputs, and a Tape input. Additionally, there is a Tape output and a line output, ideal for connecting a subwoofer, a second amplifier, or a signal processor. A phono input is not included. Power management is controlled via a main switch on the rear panel, while the unit can be placed in standby mode from the front panel or remote control, with a minimal idle consumption of just 29 watts.

The rear panel layout is designed for logical organization: the removable IEC power cable is positioned on the right side, the inputs are centrally located, and the speaker outputs are on the left. The five-way binding posts feature compact, transparent plastic nuts and are compatible with both spade connectors and banana plugs. Despite their small size, these connectors ensure a firm and secure connection.

One of the eVo2i’s most distinctive features is its advanced management and configuration system. Through an intuitive interface, users can customize source names, set initial volume levels for each input, and even activate an automatic volume attenuation function when switching sources, preventing sudden level changes. This level of customization, rarely found in integrated amplifiers, reflects a design philosophy that blends performance, practicality, and innovation with timeless elegance.
