Audio Research is pleased to introduce the latest component to the Foundation Series; the VT80 Power Amplifier. From the same engineering and design team responsible for the award-winning Reference Series, the Foundation family of vacuum tube components has been created to provide incredible musical experiences. Spatial definition, dynamics and detail abound while providing the most natural musical experience.Foundation familyIntroduced earlier this year, the first three Foundation components include the LS28 line stage preamplifier, the PH9 phono stage, and the DAC9 digital-to-analog converter. The new VT80 is the much-anticipated amplifier that allows the Foundation series to be shown as a complete system. Combining an enticing new aesthetic with worry-free operation and great audio performance, the VT80 is a vacuum-tube amplifier that will open doors to a new listening experience.Since 1970, High Definition has been more than Audio Researchs trademark; it has been the guiding principle for all products. The Foundation Series continues this passion and philosophy, offering the listener stunning playback, great value, and unparalleled long-term support.The new Audio Research VT80The new VT80 is the much-anticipated amplifier that finally allows the Foundation series to be shown as a complete system. Combining an enticing new esthetic with worry-free operation and great audio performance, the VT80 is a vacuum-tube amplifier that will open doors to a new customer base.At the heart of the VT80 are two important new features that have never been offered before by Audio Research. The first is a proprietary auto-bias circuit developed entirely in-house by the engineering department. Simply drop in the tubes and the VT80 will adjust bias for each output tube. The circuit automatically adjusts for tube wear or fluctuations in the power in real time. It will also work for different types of output tubes, including 6550, KT88, KT90, KT120 or KT150. The adjustment range is wide, but matched tubes from Audio Research still provide the highest performance. Finally, an auto-bias circuit that works in real time and does not compromise performance!The second new feature includes fusing of each output tube. In case of a fault condition in a tube, an easily replaceable fuse will blow, not a resistor. This is what we mean by worry-free operation.Reference DNAWith the beautiful new look, the flexible connection options, and the great new features, thrilling audio performance remains the primary goal and the foundation upon which the products were built. Designed as part of the Foundation series, the core of the VT80 is adapted from the Reference 75, including the same power and output transformers, similar circuit topology, and many of the same parts. The 75 watt-per-channel VT80 offers striking dynamics, powerful bass, and natural clarity combined with a very holographic presentation. The result is sonically breathtaking and provides a new reference in its price range.Visit the Audio Research website.
