The Consonance Reference 150 Linear Opera Audio is a new integrated amplifier hybrid based on the technology called A Class "cold", first adopted only on our integrated amplifier Calaf, and that, in the case of the Reference R150, is combined with a vacuum tube preamplifier stage based on the valve 6H30.
Combining the advantages of Class AB and Class, the so-called Class A "cold" is a technology that allows you to achieve the same linearity and the same performance Class, but without the great need for current consumption required by the pure Class-A.
