Impera II Ref Preamplifier
The Impera II preamplifier is a showcase of our unique Inverted Triode Technology, a vacuum tube technology innovation developed by our company and utilized in the Impera II series of audio designs.
The Inverted Triode is a unique active element, widely different to any kind of vacuum tube used in audio and tube electronics in general. Three electrodes, a cathode, grid and plate are combined to give an amplification device completely different in operation than the classic vacuum tube.
Inside a typical vacuum tube an electron stream emitted from a heated cathode is accelerated toward a positively charged anode, which has a flat plate structure. The electron flow is impeded by the grid, a negatively charged wire-grid structure, placed between the cathode and anode. This operation resembles a typical fluid control valve, hence the name valve tube.
