Audio Research VT80 SE
The VT80SE was created as a flexible, great-sounding amplifier that is easy to enjoy and easy to live with, every day. A direct descendant of our Reference amplifiers that borrows from their acclaimed designs and using many of their parts, the VT80SE sounds like a much larger amplifier with impressive dynamics, control, and resolution.
A fully-balanced design
A fully-balanced design that uses only two pairs of KT150 output tubes, it can be connected via balanced or single-ended inputs. Operation is carefree; simply drop in the tubes and the VT80SE’s proprietary circuit automatically adjusts for tube wear or powerline fluctuations in real time, making the occasional bias adjustment a thing of the past.
It also works with other common output tubes like the 6550, KT88 or the KT120. Each output tube is fused, so there are no worries, all you have to do is turn it on and enjoy the music.
The VT80SE will be a revelation in your system. Its natural clarity, coupled to its intoxicating tonal palette and sheer dynamic swing, will bring your music to life.
After more than 50 years, our focus remains the advancement of the state-of-the-art in music reproduction. Every component is meticulously hand-crafted and personally auditioned before it leaves our Minnesota facility.
Our attention to detail, customer service, and product support create unprecedented value. An Audio Research component is more than a purchase, it is an investment.
