Keep It Cool: Highly Efficient, Ultra-Low-Noise Bel Canto e.One REF601M Monoblock Amplifier Drives Speakers with 300Wpc Authority

Preserve space, enjoy the freedom that comes with placement flexbility, and know that everything will always keep cool with the wide-bandwidth Bel Canto e.One REF601M monoblock amplifier. This U.S.A.-made component outputs serious power (300Wpc into eight ohms, 600Wpc into four ohms) and operates with a quiet that seemingly belies its ability to drive even the most sensitive speakers without issue.

Combining the purity of Class A designs with the feel-it-in-your bones impact of Class D types, REF601M plays with a sit-up-and-take-notice presence that will likely have you wondering how a 15-pound, 3.5 x 8.5 x 12-inch (HWD) box can manage to be so musical, authoritative, and engaging.The simple explanation owes to Bel Canto's use of NCore technology – which employs fully discrete, self-oscillating Class D architecture with a fifth-order control loop to attain vanishingly low levels of noise and distortion – and proprietary amplifiers based on Hypex NC500 module and SMPS 1200 power supply.

The DC-coupled REF601M also utilizes high-performance stages with local feedback and a first stage that supplies a majority of the gain with a high input impedance and low output impedance to drive the output power stage. Its trademarked Impedance Optimized Input Stage is a balanced high common mode rejection, low-output impedance driver that proves crucial to the overall performance and refined dynamics.

Bolstered by a 27A peak output current and selectable gain option (27dB or 33dB), REF601M aces the spatiality, dimensionality, accuracy, richness, and naturalism characteristics that allow reproduced music to come alive in your home. On the back panel, WBT NextGen five-way binding posts impart no detectable sonic signature to your speaker cables and maintain an open, grain-free nature. A balanced and RCA input, trigger switch, and simple on/off switch complete the simple layout. Setup couldn't be easier. Neither could enjoying the improvements a pair of REF601Ms will make to your system.
