Bel Canto e.One S125 Dual Mono Power Amplifier

The Bel Canto e.One S125 amplifier is a dual-mono audio power amplifier that delivers 130 watts into 4 ohm loads per channel. Each amplifier contains its own dedicated regulated power supply for all amplifier stages, including the output section.

• The S125 amplifier incorporates performance enhancing technology resulting from our on-going research in analogue switching amplifier technology
• High common mode rejection, wide dynamic range custom input stages are added. This input stage improved the drive to that 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: Audio grade metal film resistors. Solid Electrolytic ultra-low ESR decoupling capacitors and low noise regulated power supplies. These devices ensure that the input section is utterly transparent
• The S125 uses 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

The S125 brings amazing accuracy and detail to high performance entry level audio amplification. With 65 watts into 8 ohms and 130 into 4 ohms, and a remarkable 117 dB dynamic range, the S125 redefines expectations. Our custom input circuitry and care given to all aspects of the design ensure that the S125 is an amplifier that everyone can enjoy.

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 ensuring you experience the most accurate sound that brings music to life.

The input stage uses quality amplifiers and passive components including: Custom Precision 0.1% resistors, Solid Electrolytic ultra-low ESR decoupling capacitors and low noise regulated power supplies. The elegant switching output stage eliminates thermal distortion mechanisms caused by changes in operating temperature. The combination of Bel Canto’s input and output circuitry ensures you’ll experience breathtaking truth in signal amplification that is life-like in its dynamic detail and resolution.

The compact stereo design of the S125 allows versatile system building. When combined with one of our new DAC products a complete electronics package 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. Bel Canto music products are fine instruments, discrete and sleek enough to flatter any room while delivering music with subtle impact and beauty.
