Combines all the advantages of a tube circuit in the high-end with the virtues of a phono signal optimum.
The powerful power supply is protected from interference by EMI and RFI.
The entire section of the preamp for MC is realized with a transformer with the craft selected, characterized by a high bandwidth.
The RIAA equalization is designed to passively, and is free of any interference in the radio frequency or of the electromagnetic type.
The winding of the transformer is made entirely by hand, and the welds in the inside are made, point-to-point.
The result? To listen absolutely!!!
A timbre rich, great dynamics and extension in the frequency do prephono valve Opera Audio Consonance Reference R40 an absolute reference point in the panorama of the HiFi.
