The LP1 is a departure for us in both size and series designation. The chassis is a compact 13” wide, by 8.6” deep, by 4.5” high. The front panel has the inset Audio Research logo with an engraved line completing the panel, but no handles.  There are simply two switches for Power/Off and Mute/Operate. The entire chassis is silver, and the front panel is only available in Nat...[more]

The LP1 has 47dB of gain, perfect for higher output (>1.0mV) phono cartridges. It is a hybrid design utilizing one 6H30 tube, special low noise JFETs, custom Audio Research designed power transformer (made in the U.S.), and multiple stages of regulation. There is no overall feedback, and it is non-inverting.  Inputs and outputs are single-ended. Controls are as simple with switches for Pow...[more]

Building on our thirty year tradition of designing electronics of the highest quality and value, Audio Research is pleased and very excited to introduce the LS12 stereo preamplifier, which bridges the usual gulf between solid-state and vacuum-tube sound, sonically outperforming the competition anywhere near its retail price.   The LS12 represents a major advance in solid-state circuit design ...[more]

Since its introduction in 1999, the LS16 has been a best-seller, combining a relaxed, engaging musicality with good flexibility and connection options. So why change a good thing? Well, the enhancements introduced in the Mark II versions of both the Reference 2 and LS25 have proven so popular that we feel it is time to incorporate many of the same technological improvements into the LS16MKII.Funct...[more]

On the front panel, the changes are more obvious. A new linear LED display provides a 20-lamp display for the 104-step volume control, as well as indicators for selected input and muting. One rotary control is provided for volume adjustment, while a second controls input select. Pushbuttons are provided for power, monitor, processor (unity gain) and mute. All functions are also accessible via the ...[more]

The LS17 SE maintains the same physical size as its predecessor.  The only cosmetic difference is the updated front panel which replaces the black plastic buttons with round metal buttons, complementing the symmetry of the two control knobs flanking the LED display.  The display shows volume as well as which input is selected.  Front panel controls include power, monitor, mute and p...[more]

The LS25 MKII vacuum tube stereo line preamplifier offers sonic performance, functional flexibility and value second only to the world-renowned Reference One preamplifier. Chassis construction is like the REF1, with finished slab sides and heavy top and bottom covers; chassis height and depth are slightly reduced, however. Front-panel control layout is also familiar: microprocessor-controlled r...[more]

The LS27 not only offers remarkable resolution, musicality and dynamic impact, it is Audio Research's most flexible line-stage and able to adapt to most any situation. In terms of control options, the LS27 has selectable High / Medium / Low gain settings for each input, BAL / SE input selection, Left-Right Balance control, Invert (phase), and Stereo / Mono selection. Tube hours can be monitored, t...[more]

LS28 Line Stage Preamplifier 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 a...[more]

The new LS8 MKII is a pure Class-A circuit design with a large, fully-regulated power supply and is hand-assembled to the same critical standards as other Audio Research products. MKII component improvements include new regulator FET devices, higher-quality resistors, new Infinicap(r) coupling capacitors and our latest selected 6922 twin triode vacuum tubes. Mechanically, the MKII incorporates new...[more]
