Audio Research are pleased to introduce the VT80SE, the 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 VT80SE 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 they have been deeply enamored with the KT150 as Audio Research feature it in all of their 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.

It is important to mention that the KT150 tubes supplied by Audio Research, for all of theirr products, are tested and measured for quality control and assurance, and are burned in for 48 hours. Then using the “Certified Matched” process, they are hand matched in sets with tolerances 10x tighter than standard off-the-shelf tubes, thus ensuring the finest audio quality possible.

With its auto-bias design, the VT80SE can also be used with KT120 or KT150 output tubes and the circuit will adjust immediately when a new tube is installed. Protective fuses are installed for each output tube and can be replaced if the need ever arises. What sonic improvements will you hear with the VT80SE? As their Warren Gehl said, “More music!” Tonal color, detail, dynamic swing and purity are all improved, along with a bigger and more robust presentation. The music gets better, in every way.

Aside from the beautiful curves of the KT150 tubes, the only other way to distinguish the SE from the original VT80 is by a small sticker on the rear panel. Nothing else needed to change. The existing (optional) ventilated tube cover can be used with the taller KT150 tube set, there is still sufficient space to breathe. Hear for yourself how good your system can sound with the new VT80SE, it will make a tube-lover out of anyone who loves music.
