Bel Canto Black ASC1 Asynchronous Stream Controller

Bel Canto Black ASC 1 Asynchronous Stream Controller

You are looking at something very deceptive. An almost invisible, slim profile chassis. Its lone display lets you know what you’re playing and its digital details. Subtlety and discreetly. Almost in a whisper. Pick up Black’s solid metal remote. This simple yet elegant interface allows for intuitive control. Black also allows you to interact with it using a smart phone or a tablet. Beneath its aircraft grade solid billet aluminum chassis lies multiple proprietary technologies. The result of this unique topography will stop your breath when listening to your favorite music. Black’s ASC1 controller unit is like nothing else available today. It contains Proprietary Asynchronous Interfaces along with Bel Canto ULN Master Clocks that are within centimeters of critical output and ADC stages. This prevents noise and interference from affecting the signal purity within the ASC1.

Black’s proprietary StreamLink ST fiber cable links the ASC1 to Black’s PowerStream Mono Blocks. This means perfect signal distribution: complete Galvanic Isolation, Zero Interference from ambient noise and zero noise radiation. This proprietary interface also means Black’s controller can be located anywhere you like: from a few inches to meters away from the Mono Blocks with no loss in signal purity.

Conclusions: “Black by Bel Canto Design is a breakthrough product and, because of its sound quality , the most intriguing one I’ve reviewed—and by now, that’s a lot of products. Its operating flexibility, system integration, and ease of use alone make it a must-experience product for audio enthusiasts looking for a unique, 21st-century listening adventure. If you’re a digital-only audiophile, particularly a 16-bit/44.1kHz “Red Book” one, you might find the Black’s the most compelling digital sound yet. I did, and I don’t like CDs at all. Yet I found some respite with the Black, and not because it obscured the problems many of us have with CDs—in fact, the opposite. The Black’s reproduction of hi-rez files produced the expected sonic benefits. Live digitized vinyl playback sounded more similar to than different from hi-rez digital files, but through the Black, all of these formats sounded very different from how they sounded through my reference non–class-D system: CDs for the better, the others less so. Class-D amplification sounds fundamentally different. In the case of the Bel Canto Black, it can be credibly argued that it can sound better. If you’re a committed analog listener, you’re probably going to want to listen to vinyl in the analog domain. (But if you have an opportunity to hear an LP through this system, do it.) Otherwise, here, finally, is a class-D product that, though sounding definitely different from the older technologies, makes a strong case for equality. That’s saying a lot.”Michael Fremer

“This is not a cheap pleasure, but I want it once formulated as follows: Very rarely have I encountered a high-priced combination, the latest technology, functionality, processing, sound and absolutely independent ideas together so confidently consistently.
Conclusion: Madness. Bel Cantos Black system is a completely new approach and seek out sound experience that is unique.”

Bel Canto Black System ($50,000): Known as the Black System, these components represent a reimagining of Bel Canto Design’s overall approach and are a significant step forward along its journey for designing and implementing new technologies in its product line.  Specifically, the Black System is a highly sophisticated set of electronics incorporating a unique system architecture.  According to John Stronczer, CEO and Chief Architect at Bel Canto Design, the goal of this integrated system approach is to preserve and maintain the pure integrity of the source signal through the entire system all the way to the loudspeakers regardless of the input source.

The Black System configuration includes the ASC1 Asynchronous Stream Controller, a pair of MPS1 Mono PowerStream units and High Speed Optical Interconnect (Streamlink). Over the past year or so, I’ve had opportunities to hear early preproduction versions as well as the final production units of the Black System.  For my ears – the final result is nothing short of striking.  The Black System is a truly state of the art design and provides a level of sonic purity and musical authenticity that is undeniable. Listening to reproduced music through the Black System provides an experience that is highly engaging, totally entertaining with a feeling as though you are in the presence of the artists on the recording. (Bill Wells) – STEREOTIMES Review
