The REF500M drives your loudspeakers with an unprecedented level of sonic accuracy and power. The REF500M delivers 121dB dynamic range and 250 watts into 8 ohms, doubling to 500 watts into 4 ohms. The combination of fullyregulated switch-mode power supplies and analog control circuitry brings incredible dynamic expression to your music.
Bel Canto’s e.One switching amplification imparts many advantages including low noise, low heat and low power consumption. It’s also the most direct way to convert electrical power into music. The entire music signal is delivered to the loudspeaker efficiently without excess energy wasted as heat. The compact, heavy gauge, all-steel chassis prevents micro-phonic noise from corrupting the audio signal and brings music to life with extraordinary nuance and power.
The REF500M custom power input stage includes high speed, low noise rectifiers and large storage and filter capacitors that substantially increase energy storage, significantly lowering noise while reducing sensitivity to power line fluctuations. The custom 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. The combination of Bel Canto’s input and power circuitry ensures the full dynamic expression in your music is experienced.
The Mono-Bloc design of a pair of REF500M amplifiers allows great flexibility in placement, either near your source components or your loudspeakers. The total isolation of each channel also results in the holographic stereo imaging and separation. The elegant switching output stage eliminates thermal distortion mechanisms caused by changes in operating temperature. You’ll experience breathtaking truth in signal amplification that is life-like in its dynamic, detail and resolution.
Bel Canto music products are fine instruments that deliver music’s subtle detail, impact and beauty. Green, low-heat, ultra-efficient heavily regulated switch-mode power supplies and switching output stage make possible Bel Canto’s eco-friendly compact designs that are sleek enough to flatter any room; place two Bel Canto e.One products in the space formerly occupied by a large, hot-running, inefficient class-A design!

|“While you may come for the power of the REF500M monoblocks, you will stay for the musicality … Considerably sweeter than their predecessors … more open and transparent, with greater clarity and control (particularly of the bass) … A more relaxed presentation (particularly on the top end), and really remarkable rhythm and pacing. … I experienced all audio events as occurring in real time; in the here and now … ample power reserves track the leading edge of transients, as well as the rise and fall of dynamics with incredible accuracy, timing and presence … with a focused, convincing soundstage. Musically, you want for so little, it’s hard to imagine wanting anything more.” Full Review|
|“My extended time with the Bel Canto e.One REF500Ms put to rest all doubts or misconceptions I’d had about class-D switching amplifiers — they could play with the big amps of any class. The REF500Ms displayed excellent transients and dynamics, legitimate high-end microdynamics, and good depth and soundstaging, among their other attributes. And for Manhattan apartment dwellers and others with limited space, their small size is a huge asset. The e.One REF500M represents good value for what, these days, is a reasonable price in highend audio. It’s hard to go wrong with these beauties; they prove that small can be beautiful, even in the high end.” Full Review|
|“The Bel Canto REF500Ms are far from being mere raw 125ASX2 modules hidden inside handsome boxes. Like the power conversion components imbedded in so many advanced amplifiers based on other underlying technologies, the ICEpower 125ASX2s are but central building blocks of a comprehensive design, optimized to yield astonishingly high musical performance. … Harmonic exposure, development, and congruence is wholly convincing … Give the Bel Canto REF500Ms a long audition: you will be amazed by their surprising authority, seduced by their agility, and will fall in love with their superior musicality.” Full Review|
|“Green has become the new buzzword for socially-conscious living. In this area, audiophiles have been woefully behind the curve with cabinets full of energy-sucking electronics. Bel Canto REF500M amplifiers give you great sound AND sips lightly from the energy stream. My last class A power amplifier regularly pulled an extra $30 per month from my wallet. By contrast even when left on 24/7 the REF500Ms drew less than $30 of juice in an entire year! You can hear all the wonders of Miles Davis’ ‘Kind of Blue’ while staying completely green. In short, welcome to the new electronic millennium!” Full Review|
