Descrizione

(dal sito del produttore)

The REF150S brings remarkable sonic qualities to lower power amplification. The REF150S delivers 117dB dynamic range, 75 watts into 8 ohms and 150 watts into 4 ohms with power to drive a wide range of speakers. The combination of fully-regulated 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 REF150S 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 compact REF150S stereo is the start of a compelling audio system. When combined with one of our DAC models a complete electronics package will use less than 15 watts and take up no more space than a standard integrated amplifier while delivering performance expected from only the best separates. 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 extremely dynamic, detailed and resolved.

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 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!

“Minneapolis-based Bel Canto Design introduced a new superefficient dual-mono (stereo) 150-watt amplifier, the e.One REF150s. I really love the sound of Bel Canto amps, and I love that they draw very little power, usually less than 30 watts from your wall outlet.”

“During my time with Bel Canto’s entry-level REF-series stereo amplifier, I quickly grew to appreciate its sound. The almost tube-like refinement with which it passes along whatever signal its amplifying has proven very seductive. The Bel Canto e.One REF150S is the most musical amplifier I have heard south of $5000, with the exceptions of its bigger brothers, the REF500S and REF500M. If you’re in the market for a wonderfully musical two-channel amplifier that offers tremendous value and performance, rock-solid build quality, and uses a minimal amount of power, you owe it to yourself to audition Bel Canto’s e.One REF150S.”
