bel canto ref500s power amplifier

The Bel Canto REF500S stereo power amplifier is capable of a genuine 250wpc into 8ohms (500wpc into 4ohms), with an extremely low distortion rate of 0.003% and high damping factor of over 1000. It's capabilities and quality are helped by its HDR Core technology - comprising of ultra-low-noise master clocks, advanced asynchronous interfaces, and dual-mode low-noise high efficiency power supplies.

Another amazing aspect of its technology is its flat frequency response, which is +/-3dB from 1.5Hz all the way up to 70kHz.

Because the Ref500S stereo power amplifier runs cool, thanks to its advanced Class D technology, it is ideal for tight or enclosed spaces, or even stacking. The REF500S shares the same compact casing and brushed aluminium fascia of the rest of the e-One range.

A pair of analogue RCA inputs provides a connection for most amplifiers or pre-amplifiers, with the addition of balanced XLR inputs for higher quality hi-fi components.


A set of high quality WBT Nextgen 5-way binding posts provide a firm connection for spade or banana plugs for the best possible connection for your cable/loudspeakers.

And all this in a smaller box than a Cyrus Stereo 200 amplifier.
