Audio Research VT80/ LS28 ULTIMATE COMBO DEAL, opened but pristine set...

We're super excited to be able to offer a once off deal on the very special Audio Research VT80 power amplifier and LS28 preamplifier. Capable of delivering power and control to even the biggest of speakers, the VT80 is a real stallion in the Audio Research stable. But this isn't an ordinary stallion - it's a dressage stallion that can perform intricate, balletic movements on cue...a glorious synthesis of power and refinement.

This unit is equiped with the KT120 Tubes however these can be swapped out for the KT150 tubes if you so desire. That'll turn this unit into the VT80SE. 

The LS28 is similarly that kind of preamplifier that is an end of the line, no more upgrades necessary kind of preamplifier. Equipped with four 6H30 tubees, the precision, quality and thought that has gone into the circuitry means the noise floor on the LS28 is extraordinarily low. The biggest gain to be had to my ear because of that is ooooooodles of bass extension as well as more fine detail. 

This pair has been opened but is essentially untouched and that's why we can offer it to one lucky person at this price. Both units are Silver (Natural).

Product Description



The LS28 line stage is a flexible and intuitive preamplifier. Four balanced and four single-ended inputs, and two sets of both balanced and single-ended outputs, allow maximum connectivity. The straightforward menu allows control of numerous parameters, including input naming, tube hours, auto shutdown, and home theater passthrough. Phase invert and mono are also standard functions. At the heart of the LS28 are four 6H30 vacuum tubes in the analog circuit. While the LS28 is the perfect match for any Audio Research amplifier, it has been designed to work with nearly any amplifier on the market today.

Since 1970, High Definition has been more than our trademark; it has been our 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 VT80 is the much-anticipated amplifier that finally 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 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 our 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.

With the beautiful new look, the flexible connection options, and the great new features, thrilling audio performance remains our primary goal and the foundation upon which we 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 VT80SE 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.
