Classé has announced the expansion of its popular Sigma series to include a new monaural amplifier. The first three Sigma series models, launched earlier this year, were designed to deliver a compelling performance and feature set at prices below the entry level of other high-end brands but within easy reach for anyone considering the top-of-the-line offerings of more mainstream companies. The Sigma MONO broadens the appeal of the Sigma range with a powerful amplifier, conservatively rated at 350W into 8 ohms and 700W into 4 ohms.SigmaMono_front

“In the short time they’ve been available, our proprietary Sigma series amplifier designs have been showered with praise from numerous audio critics and consumers worldwide, “said Dave Nauber, President of Classé. “The Sigma MONO builds on this innovative platform, pushing the performance to heights that surprised even us – and we’re pretty hard to surprise!  SigmaMono_gut_white

The pure, effortless sound that is the hallmark of the Sigma MONO derives from an unlikely source: a massive switch mode power supply,” . “Critical portions of the amplifier’s circuitry surpass what is available in the two- and five-channel Sigma models. A new analogue input stage, modifications to the operation of the output stage, and new output filters are employed to optimize the performance of this high-powered monaural amplifier.”SigmaMono-back_white

A special pass-thru feature allows the input signal to be forwarded to a second amplifier for bi-amplifying or to drive a subwoofer amplifier. This allows the amplifiers to be located closer to each speaker: a single long interconnect can be used to connect the preamp to the first amp, followed by a short interconnect to the second Sigma MONO – or even a third and a fourth.

The US retail price for the Sigma MONO is $4,000, with availability in October.
