Bel Canto e.One REF500S Stereo Amplifier

Bel Canto e.One REF500S Stereo Amplifier

The REF500S stereo amplifier has incredible power per square inch with two independent mono boards in a single chassis. Independent power supplies and isolated input signal filter technology reduces high power amplifier energy for a cleaner, transparent power.

• Max Power Output: 500W 4 ohms, 250W 8 ohms per Channel
• Minimum Load: 2 ohms per Channel
• Peak Output Current: 35 Amps per Channel
• Balanced Input Impedance: 200 Kohms

Features

Impedance Optimized Input Stage

The Bel Canto Impedance Optimized Input Stage is a balanced high Common Mode Rejection, low output impedance driver that is critical to the amplifier's performance, ensuring that the refined dynamic qualities of the recording are preserved.

WBT NextGen Speaker Connectors

The WBT NextGen connectors provide the best possible connection from the amplifier to the speaker cables. We choose them because they impart minimal sonic signature to the sound, remaining open and grain-free up throughout the audio frequency band.
