The Sigma MONO is the reference design for the proprietary Classé amplifier platform introduced in the Delta series CA-D200 and Sigma AMP2 and AMP5 models. With completely separate chassis for each channel, the monaural amplifier architecture eliminates the possibility of crosstalk between channels and allows speaker cable lengths to be held to a minimum to minimize losses. It efficiently delivers a prodigious 350W into 8Ω and 700W into 4Ω, suitable for the most difficult speaker loads and critical listening applications.
