About the Cyber 800

The Opera Audio Consonance Cyber 800 is a dual mono vacuum tube power amplifier designed with a classic push-pull amplifier circuit. It uses two 6922 double triodes for amplification and inversion, a 5687 double triode to drive four Russian 6CA7 EH power tubes in parallel. The final stage operates under low distortion and self-bias conditions. The amplifier delivers 78 watts RMS per channel at 1kHz in ultra-linear mode, with total harmonic distortion less than 1% at 50 watts. It features selectable output impedance (4 or 8 ohms), an input sensitivity of 700mV, and a frequency response from 6Hz to 100kHz (-3dB points at 50 watts). The amplifier uses premium Electro Harmonix tubes and high-quality components, including hand-soldered parts and exclusive capacitors. It weighs 30kg per unit and measures 420mm (L) x 185mm (W) x 330mm (H). The Cyber 800 is known for its solid build, musical clarity, and flexibility with triode or ultra-linear operation modes. It is often paired with the Cyber 222 preamplifier for a complete system. The product is still available new with a one-year warranty.
