    e.One e.volution

    Bel Canto has created cutting edge audio products for over 20 years, designed specifically to convey the subtle details in the original recording. Our e.One products achieve this goal by developing efficient new technologies and superior designs.

    All of our e.One products are designed and hand-built with pride in Minneapolis, MN USA.

  • Design


    DAC 2.8, CD3t, and REF501S amplifier

    Deceptively but Respectfully Simple

    Each product in the e.One line conforms to this elegant approach.


    Strong, Compact Steel Chassis

    Our choice of material and structural design minimizes environmental interference and preserves signal quality. The feet consist of a special anti-resonance polymer specifically designed and manufactured for minimal vibration transference.

    Pride of Ownership Begins with Refined Details

    Each faceplate is precisely cut from high quality aluminum, designed to reflect the overall refinement and attention to detail of each e.One product. The faceted edges and curved lines catch the light beautifully. Available in either clear or black anodization.

    Elegant Display and Control

    The e.One interface design is intentionally minimal, useful, and efficient. The focused dual-function knob gives you full control of volume, channel selection, and mute within a few turns or presses. The green multifunction display is easily read from a distance. Our 4 digit display is simple and efficient, and the programmable 8 digit alphanumeric displays provides customized operation and naming of inputs. Either display can be turned off for unobtrusive operation. The included 36 button remote allows instant fingertip access to every function.

  • Technology



    Preserving and conveying the original nuance of a recording drives our choices in technology and circuit design. Though not the easiest path, we have found that it leads to true musical expression. Not just a new or different ‘sound’ quality, this approach results in true advancement of the audio art and your listening experience.


    Bel Canto’s High-Dynamic Resolution (HDR) Core is fundamental to the integrity of our Digital to Analog Converter design. HDR Core is the result of over 20 years of R&D into optimum DAC architecture. The HDR Core incorporates refinements in power supply architecture, asynchronous retiming of all digital inputs, ultra low noise (ULN) master clocks, full ClassA I/V and voltage amplifier stages and carefully selected passive devices to ensure that all of our DAC products provide market leading transparency from any musical source.


    Our Asynchronous technology used in the Ethernet, USB and SPdif interfaces removes the source clock and creates an isolated, free running ultra-low phase noise (ULN) Master Clock that precisely retimes the incoming data, eliminating the timing errors that cause the loss of subtle detail in a recording. We use the highest accuracy crystal oscillators (ULN Master clocks) to generate a low noise reference at a single frequency, these clocks achieve extremely low phase noise measured in Femtoseconds. This is 100 – 1000 times lower than typical clocks. Only our asynchronous design with a free running ULN Master Clock can achieve the high performance levels that retain the accuracy and detail of the original recording.


    All e.One amplifiers are designed with Bel Canto's Impedance Optimized Input to ensure optimum balanced signal drive to the amplifier module and optimal impedance balanced signal loading from the controller output stage. The input stage ensures low noise and low interference operation in a real world environment, preserving signal integrity. Many e.One amplifiers also take advantage of our custom AC/DC input filter and energy storage stage to allow the amp module to operate in a better controlled environment, providing lower noise operation and better dynamic signal handling, making the amplifier sound ‘bigger’ and conveying dynamic nuance more accurately.


    Analog switching amplification goes beyond traditional class D amplification, using self-contained feedback loops that ensure stable high audio quality over a wide range speaker loads and a Controlled Oscillating Modulator that suppresses non-linearity in the output stage. Multiple feedback systems produce very low amplifier output impedance resulting in very precise bass control that is superior to class A/B. The fully regulated SMPS switch mode power supply is fast (recovers from massive bass impulses quickly), efficient (creates little heat maintaining linearity) and clean (will not pollute the power line). Our advanced amplification and power technology provides the most transparent sonic path to the loudspeaker.

  • System


    bel canto amplification system

    Design Synergy

    e.One products are designed to work as a complete audio system from source to amplification, delivering maximum performance and transparently pristine audio reproduction in a compact, efficient footprint. While each component is designed robustly to enhance any audio system, a system assembled with all e.One components will provide the most transparent path from source to loudspeaker.

    Digital Evolution

    As Bel Canto digital audio technology has evolved over the past 20 years the realization of our truly transparent HDR core has naturally lead us to see the DAC as the core and control center of a modern, transparent to the source, audio system. e.One DACs offer the perfect high performance centerpiece for all audio inputs with 24 bit volume control all digital switching and a host of input options including analog RCAs. The analog signal path is optimized and minimized ensuring that the musical message remains intact at the amplifier inputs.
