Concero 65 Signature

About the Concero 65 Signature

The Aries Cerat Concero 65 Signature is a high-end 65 W single-ended triode (SET) monoblock power amplifier and the mid-tier model in the Concero 65 series, sitting above the Reference and below the Limited Edition versions. It is a two-chassis design per channel with the audio chassis separated from an external power supply, representing an improved, higher-performance evolution of the single-chassis Concero 65 Reference. The Signature shares the core Exsequor-derived circuit topology of the series, using 1 x 814 driver tube and 2 x RCA 813 output tubes per channel in a parallel single-ended triode output stage, delivering high power for a SET design, wide bandwidth, and low noise. The amplifier operates in pure Class A, employs transformer-coupled stages, features adjustable bias on the fly, user-selectable output impedance matching, and offers RCA plus proprietary AC Link inputs. As with the rest of the Concero 65 line, it is noted by dealers and enthusiasts for unusually strong bass control, dynamic drive, and low noise floor relative to typical low-power SET amplifiers. The Signature version commands a higher price than the Reference and is listed by dealers around US$75,000 per pair, though Aries Cerat's own product page does not publish a formal MSRP.
