Audio Research was founded in 1970 in Minneapolis with one goal in mind: to advance the state-of-the-art in music reproduction. Today, Audio Research remains a performance-oriented company by philosophy and design. New product introductions are driven only by genuine advances in technology and performance -- the HIGH DEFINITION that is the hallmark of the company's products.
Audio Research Reference 5 SE
With a new larger power supply and technology from the now famous Ref 40 Anniversary Preamp, the new REF 5 SE is the latest model in a series of the finest and most successful line-stage preamplifiers ever made. From the REF1 to the REF2 to the REF3 to the REF5, each one has built upon the legacy of its predecessor as the most sought-after reference level line-stage preamplifier. The REF5 SE clearly redefines the state of the art at a price that is not inexpensive but represents extraordinary value.

Audio Research DSI-200
The DSi200 delivers 200 WPC continuously into an 8-ohm load, 400+ WPC dynamically into 8 ohms, and 800+ dynamically into 4 ohms. This allows the it to control large, power-hungry speakers with remarkable ease. All this is generated with almost no heat. The DSi200 is a fully balanced design offering two sets of balanced inputs and three sets of single-ended inputs. One set of single-ended inputs can be used as a normal line-level input or it can be converted into a home-theater passthrough. The heavy front panel features Volume and Input selectors flanking a vacuum-flourescent display.

Audio Research DAC-8
This reference quality 24-192khz DAC has a USB input for accessing stored music on your computer, also RCA, BNC, XLR and optical digital inputs. Audio Research has maximized the USB capability of the DAC8 by incorporating USB 2.0 HS (High Speed) which runs at 480Mbps. USB 2.0 HS has a lower jitter specification than USB 2.0 FS (Full Speed 12mbps), consequently the DAC8 is capable of reproducing music at higher definition/resolution (up to 24/192) than products communicating at USB 2.0 FS speeds (24/96). The remote control allows you to track skip using Windows Media player or iTunes. XLR or RCA analog outputs. Black or silver faceplate.

Audio Research DS-225
Audio Research’s proprietary Class D all-discrete analog switching mosfet output technology combined with a large, linear analog power supply, yielding tremendous speed and power delivery, but doing so with cool-running efficiency, idling at only 38 watts. The DS225 is a global feedback-free, fully-balanced design with both XLR balanced and RCA single-ended inputs. It has an uncanny ability to resolve information and place musicians firmly within a large soundstage even at low levels. You’ll hear none of the “dead zone” effect at low volume that is common to other conventional switching designs. Bass control, reach and impact are all superb, while musical dynamics are instantaneous. In addition, the amplifier has an extremely low noise floor, allowing instruments to emerge from a black background. Tonal balance is neutral, fine grained and relaxed. Like all Audio Research products, the DS225 is made by hand in Plymouth.

Audio Research Reference 75
The REF75 is a great looking amplifier, slightly reminiscent of our older classic designs. The front panel has two illuminated analog power/bias meters, one for each channel. Under each meter is a knob to switch from power output to bias monitoring for each output tube. The outer dimensions of the REF75 are identical to the REF150. The front panel, handles, and top cover are available in Natural or Black. Power output is 75 WPC continuous, based upon a push-pull, fully-balanced circuit (like the REF150), with only one matched pair of KT120 output tubes per channel. The input stage utilizes direct-coupled JFETs with a single 6H30 driver tube per channel. Like the REF150, output stage coupling is a combination of “Ultralinear” andAudio Research's patented “partially cathode coupled” topology, yielding better sound than conventional pentode or triode operation. Because of its modest heat output, cooling fans are not necessary. The REF75 is a wonderfully refined amplifier with stunning transparency, resolving power, and tonal color. Its effortless dynamics and bass impact allow it to be paired with the finest full-range speakers. The REF75 plays big and with great finesse.

Audio Research LP-1
With the enthusiasm for high quality analog music playback remaining undiminished in today’s digital world, we are pleased to introduce a new phono stage designed primarily for higher output cartridges. The LP1 will offer high value and truly great performance. 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 Natural. The LP1 has 47dB of gain, perfect for higher output (>1.0mV) MM and MC 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 noninverting. Inputs and outputs are single-ended. The LP1 simply sounds wonderful, with great transparency and a lovely tonal balance. Typically Audio Research, the LP1 has dynamic life, passing gobs of information and sorting out the most complex musical passage. Airy on top, resolute on the bottom, the LP1 is fun to listen to and distances itself from the competition. Put it in any system at hand and have a great time with some vinyl.

Audio Research Reference CD-9
The REF CD9 incorporates four digital inputs: Asynchronous USB 2.0HS, AES/EBU, RCA, and Toslink. All inputs handle 24 bit / 192k resolution. As you would expect, the REF CD9 retains the Philips PRO2R transport, still the best dedicated CD mechanism available. It is simply unsurpassed for compact disc playback. Like the REF5SE, REF PH2SE and REF DAC, the analog section is vacuum-tube, with four 6H30 dual-triodes, and there is vacuum-tube power-supply regulation featuring a6550WE with a 6H30. Sonically, the REF CD9 is in a new class, combining the magical musicality of tubes with new levels of transparency and aliveness. The REF CD9 sounds “faster” with greater transient speed, improved dynamics from top to bottom, much greater resolution of inner detail, with a focus and purity that is captivating. Rhythm, pace and timing are better than ever, something you must hear to appreciate.
