The Definition Series of amplifiers represents an unusual type of "solid-state hybrid" design in which a massive, highly regulated, linear analog power supply is combined with a truly "green" discrete analog switching-MOSFET output stage for highly efficient power conversion and low power consumption. The analog power supply and all-discrete MOSFET output stage are pure Audio Research expressions ...[more]

Like the DAC8, the DSPre offers the following:• Five digital inputs, including USB 2.0HS, AES/EBU, RCA, BNC, andToslink®, all of which are capable of decoding 24 bit/192k files.• Asynchronous USB.• Utilizes quad “monoblock DAC” architecture with dual low jitter mastercrystal oscillators to eliminate decoding and quantization errors, increasethe dynamic range, and ...[more]

GS150 POWER AMPLIFIER An amplifier is the workhorse of any system – it is responsible for receiving small signals from a preamplifier or source component, and developing them into larger currents to control a loudspeaker. To that end, the GS150 has been designed to seamlessly integrate into any system and steadfastly perform its task. Challenging source material and difficult sp...[more]

A preamplifier, amplifier, phono stage, and digital to analog converter all in one chassis, the GSi75 combines with your favorite speaker to deliver a singular and simple solution to control your listening system. Unlike other integrated designs that make performance - sacrificing compromises to fulfill a price point or form factor, the GSi75 harnesses the power and technologies developed by...[more]

GSPre PREAMPLIFIER The GSPre is the nerve center of a system – not only directing signals and providing attenuation, but also interpreting and deciphering complex signals to create a musical story with the drama and intrigue befitting your favorite songs. The job of a preamplifier is to do its work discretely, leaving the musical signal with as little signature as possible ...[more]

We call it "Hybrid Drive" because that’s how it works.  As in the REF110, a JFET input (for low noise) feeds a 6922 dual triode gain stage, which in turn feeds a 6H30 dual triode cathode follower which drives the outputs through our proprietary coupling capacitors (first used in our REF3 preamp).  This vacuum-tube input/driver arrangement sets the stage for superbly musical perform...[more]

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]
