Audio Research VT80 SE

The VT80SE is the upgraded version of the VT80 model, one of the most popular Audio Research amplifiers among absolute sound enthusiasts around the world. The most relevant change provided by the VT80SE is the improvement of the output valves, with the imposing KT150 replacing the KT120 of the original model.

Audio Research 's “love story,” so to speak, with the KT150 is reflected in the fact that it is used in four other models of the brand, from the VSi75 stereo integrated amplifier to the enormous REF monophonic power amplifier. 750SE, as a result of its incomparable performance and a useful life of 3,000 hours that provides years of uninterrupted listening.

As far as circuit topology is concerned, the VT80SE uses a one hundred percent balanced architecture that allows it to deliver a power of 75 continuous watts per channel. On the other hand, the open structure of its extruded chassis simultaneously provides beauty - with a perfect integration with the rest of the models in the series to which it belongs, that is, the Foundation - and a rigid foundation for the two 6H30 attack valves and the four KT150 output valves used.
