Bel Canto Black

Black is like no other audio system in the world. It communicates the musical experience completely, staying true to the recorded event and conveying the passion the artist intended. "2019 Stereophile Class A Rated"



Achieving this level of detailed playback required rethinking the way signal travels through the many stages of the electronics system. This was the challenge behind Black and the reason we took a different approach, designing a 3 chassis integrated hybrid system.

Beautifully constructed from solid high grade billet aluminum, the modern look and feel of Black connects to all sources offering the highest level of flexibility and ease of use. Black creates an authentically present and naturally dimensional musical experience that will captivate you.

The Ingenuity of Black by Bel Canto

Black is a highly-optimized audio system that communicates the most subtle detail in a recording. Black has the synergy of integration and the optimization of separates, creating one system to bring out the clarity and naturalness in music. Designed and manufactured by Bel Canto in Minneapolis Minnesota, the Black system delivers an unparalleled level of sonic realism. We invite you to take a look inside.

The Technology of Black

The Black system architecture incorporates the most advanced digital and analog audio technologies and a series of unique electronic and mechanical design solutions aimed at preserving the delicate audio signals. Black’s bold design isolates source and DSP processing in the ASC1, creating an ideal signal transfer to the MPS1 monoblocks where digital conversion and amplification takes place in an optimized environment. Each innovation in Black adds up to create an audible experience that is simply remarkable.

Bel Canto's Ultra-Low Noise (ULN) Masterclock Circuitry

The mission of Black’s ULN Masterclock circuitry is to flawlessly re-time the digital audio signal, removing any jitter related digital noise before being sent to the MPS1s for final conversion to analog. In order to take full advantage of 35 Femtosecond clocks great care is taken in the physical layout of each technology that plays a critical role in overall signal performance. Each input is extremely close in proximity to the DSP core, Masterclock and power devices creating very short signal paths to the output, and maintaining the ultimate signal integrity.

Bel Canto’s ULN Masterclocks circuit push the limits of low phase noise and jitter. Our research has shown that lowering the noise levels well beyond previous limits provides the absolute transparency and musicality that defines the true potential of digital audio. The phase noise levels of our ULN Clocks are below 35 Femtoseconds from 100Hz to 1MHz, with a clock noise floor of -170dB we are virtually equivalent to the noise floor of 24 bit PCM audio limit. While difficult to measure, the sonic superiority of our ULN Master Clocks is easily heard.
