The Consonance Cyber 800 are a 'no compromise' Reference version of the already excellent M800SE Monoblocks. The circuitry is basically the same although the input stage of the Cyber Series is used and the output stages uses 6CA7 tubes instead of the EL34 in the M800. Although these two tubes are basically the same, the 6CA7 gives a better controlled and deeper bass performance when used in this configuration.

The more advanced and heavier duty Cyber power supplies are also used. These improvements added to the absolutely awesome build quality of the Cyber cases result in an especially impressive amplifier, both sonically and visually.
