The power amplifier is the final component in the signal chain before the loudspeakers. It is the workhorse of a hi-fi system. It takes the low-level signal from the pre-amplifier and converts it to a powerful signal to drive the loudspeakers. It has a low-level input to receive the signal from the preamplifier, and terminals for connecting loudspeaker cables.
Because of the power amplifier's unique function, it differs from other components in size, weight and use. High-quality power amplifiers are usually large and heavy. Moreover, the power amplifier is the component you don't need to touch and adjust. Consequently, power amplifiers are often placed on the floor near the loudspeakers rather than in an equipment rack.

Audio Research Foundation VT80-SE Power Amplifier
|
|
Introducing the VT80SE, the Audio Research amplifier with the widest appeal to the greatest number of music lovers worldwide. By combining world-class performance with flexibility and features like auto-bias, the VT80 has been an amp that is easy to take home and just forget as you enjoy your music collection again for the first time.
The big change from the VT80 to the new VT80SE is upgrading the KT120 tubes to the higher performance KT150 output tubes. Everyone should know that we have been deeply enamored with the KT150 as we feature it in all of our other amplifiers, from the VSi75 to the REF 750SE. Its performance is unparalleled and its 3,000 hour average life allows years of uninterrupted listening. The VT80 was originally designed with the KT120, the predecessor to the KT150, but these two tubes are electrically interchangeable and the demand for delivering the VT80 with the KT150 could be ignored no longer.
