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. Impedance Optimized Input
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. Bel Canto chose them because they impart minimal sonic signature to the sound, remaining open and grain-free up throughout the audio frequency band.
