Bel Canto’s new generation of e.One analog switching audio power amplifiers emerge…These amplifiers incorporate performance enhancing technology resulting from our on-going research in analog switching amplifier technology.
High common mode rejection, wide dynamic range custom input stages are added. This input stages improved the drive to the amplifier, resulting in lower noise and distortion and wider dynamic range in real-world operation.
The input stage uses the latest advanced amplifiers and passive components including: Caddock resistors, Solid Electrolytic ultra-low ESR decoupling capacitors and low noise regulated power supplies. These devices ensure that the input section is utterly transparent, enhancing the performance of the core amplifier.
The REF1000M and REF500M Mono amplifiers also include custom power supply rectification and filters that substantially increase the energy storage of the power supply. This stage results in lower noise in operation, reduced sensitivity to power line effects and better perceived power delivery and dynamics. Incorporating high speed, low noise rectifiers, high voltage film filter capacitors and high energy storage this filter allows the regulated power supply to perform at its best.
Both the REF500M and REF500S use 3rd generation switching amplifiers for lower High Frequency distortion, increased clarity and better high frequency extension.
All Bel Canto e.One amplifiers are gain matched for easy mixing in system building, multi-channel and vertical bi-amplification applications.

Efforts at Bel Canto to improve the third-generation ICEpower module seem to have succeeded. The REF500M monoblocks delivered on the promise of low noise, as evidenced by good detail retrieval and heft amidst notable dynamic drive and power. They were subject to burn-in and cabling issues, as most amps are. I enjoyed my time with them and suggest a personal audition - just be sure they are fully burned-in before you reach any decision. They are a step forward in the march of class-D amplification into the world of organic high-end audio.

Passion for musical expression and technical virtuosity have been the guiding principals of the founder and head designer of Bel Canto, John Stronczer. Dissatisfaction with the status quo of ‘High End Audio’ created the desire to go beyond the mundane by designing audio systems to satisfy his deep need to experience of the power and expression of music.
At Bel Canto, an audio system must be able to clearly recreate the artistic intent of the artist, producer and engineer. Music, above all, is communication and a great audio system will allow the greater part of the musical communication to come through clearly, without editorialising, distorting or confusing the message.
All Bel Canto products make use of compact and efficient design principles, Bel Canto products use less resources per unit to produce better performance than ever before. Everything from reduced packaging volume to less weight in transport helps to reduce the overall environmental impact of bringing our products to market.
The development of Bel Canto Design’s compact e.One line represents a synthesis of the knowledge gained over the past 15 years in defining and perfecting high performance audio equipment, delivering remarkable levels of audio realistic performance.
