The Bel Canto REF501S is an outstanding entry point to Bel Canto standalone power amps. It has plenty of power to drive a wide variety of speakers, but has seen a significant upgrade in the quality of power over the former REF500S with Bel Canto’s custom NCore implementation. It’s an ideal match to Bel Canto’s Pre5 preamplifier, or driven directly by the Bel Canto DAC2.8 DAC control preamp.
The sound is hallmark Bel Canto which is well-balanced, detailed and highly musical due to its smooth delivery.
Features
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.
