I am the original owner of these Bel Canto REF1000M monoblocks. The REF1000M is successor to REF 1000 mkII. They are in virtually new condition (less than 100 hours), and have RCA inputs upgraded by the manufacturer. The amplifiers were recently inspected and bench tested by Bel Canto to confirm that they conform to its specifications, and have not been used since. Each amplifier is manufacturer rated at 500 watts into 8 ohms and 1,000 watts into 4 ohms, but Stereophile test results were higher. They have fully balanced and unbalanced inputs.
The REF1000M has been favorably reviewed by everyone: Stereophile Class A, TAS Editors' Choice Award, three Blue Moon Awards and others. A number of reviewers have kept them for their personal audio systems, including Kal Robinson (Stereophile) and Russell Lechter (Stereo Times).
The REF1000Ms are compact, run cool and have great musicality and dynamic range, as well as other sonic benefits attributable to their high, clean power.
