Consonance Cyber Signature integrated amplifiers.

CS10 Signature 10 "Anniversary" version
2A3 P/P version 11wpc
As known single ended triode (SET) based amplifiers have a unique sound and so do push pull directly heated triode (DHT) amplifiers like the Cyber-10 signature. In some applications 8 watts of DHT will sound more powerful and controlled than 8 watts of SET. The heaters use AC throughout the design due to the sonic advantages over DC and at 2.5V on the power tubes hum is not a problem. The unit is build with point-to-point wiring, featuring a ready made thick-trace PCB for the choke filtered power supply. This configuration allows Cyber-10 signature sounding more close with well designed SET amps and with much dynamic bass performance as well.
As a push-pull 2A3 valve integrated, Cyber-10 Signature can't deliver a lot of raw power but it makes up for this in myriad ways. With suitable speakers, the Cyber-10 Signature is a gutsy integrated amplifier with huge dynamics. It sounds muscular, detailed, and smooth. The Cyber-10 Signature handled vocals with noteworthy clarity and intelligibility. If you need even more power, Opera Audio offers the Cyber-100S Signature integrated amp, which uses 300B triodes to produce 22Wpc.
