REF 750 SEL Mono Amplifier

REF 750 SEL Mono Amplifier

The Reference 750 SEL monoblock amplifier continues the story begun 25 years ago with the introduction of the Reference 600; that is, to create the ultimate, vacuum-tube amplifier with enough power to drive any speaker, and to provide a musical experience unlike any before it. The Reference 750 SEL redefines all expectations of what is possible from an amplifier in a music playback system. It is the culmination of everything Audio Research knows about amplifier design and manufacture – High Definition in its purest, most dynamic form.

REFERENCE 250 SE Mono Amplifier

REFERENCE 250 SE Mono Amplifier

The concept of a large monoblock amplifier is to provide control to a speaker. The difficult part of the job is maintaining finesse and musicality while doing it. Audio Research has produced some of the most critically acclaimed products during its 42-year history and the new Reference 250 SE aims to break new ground.

REF 160 M Mono Amplifier

REF 160 M Mono Amplifier

After two years in development, the new Reference 160M (REF160M) Monoblock Power Amplifier is built like no other, looks like no other, and sounds like no other amplifier that you have ever heard, but it is unmistakably Audio Research. It features a refined audio topology with fewer and better components in the signal-path than in previous designs, switchable Ultralinear/Triode operation, proprietary auto-bias, output tube monitoring and protection, an advanced power meter, and much more. This array of features has never been offered before in an Audio Research amplifier.

REF 160 S Stereo Amplifier

We are pleased to introduce the VT80SE, the Audio Research amplifier with the widest appeal to the greatest number of music lovers worldwide. By combining world-class performance with flexibility and features like auto-bias, the VT80SE has been an amp that is easy to take home and just forget as you enjoy your music collection again for the first time.

VSi75

VSi75

The VSi75 integrated amplifier breaks new ground in an ʽall in oneʼ product design, and sets a new benchmark in the lifelike reproduction of music. The VSi75 continues the design series of ʽopen chassisʼ products from Audio Research such as the VSi60 and VS115, yet incorporates new developments from the Reference series product to combine in a visually striking and sonically astonishing product. The VSi75 springboards from the award-winning VSi60 and takes the listener to new plateaus of musical enjoyment. While similar in form to the ʼ60, the chassis has been reworked and refined to reflect the industrial design for which Audio Research is known: the front panel reflects those on full-size components, the perforated cover hearkens back to earlier Audio Research products, and the chassis is a sealed, monochromatic silver to match with the rest of the components. The front panel sports a new LCD display which clearly displays input, volume and other functional information.

GS150

GS150

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 speaker loads are met with control and finesse to present a musical landscape of breathtaking proportions. Three meters across the front panel provide a window into the operation of the amplifier and give the amplifier a striking façade. The selection of premium parts internally is reflected in the beautiful metalwork of the chassis and exquisite finishes. The circuit is design features the new KT150 power output tubes for 150 watts of effortless power delivery. A reflection of the past yet clearly a guiding light into the future of music reproduction, the GS150 is poised to deliver years of musical enjoyment.

DS225 STEREO POWER AMPLIFIER

DS225 STEREO POWER AMPLIFIER

The DS225 adds another chapter to the Definition Series amplifier story, taking the proven format of the DS450 and scaling it down slightly in size and power, producing an ample 225 WPC into an 8-ohm load.

REFERENCE 150 SE Stereo Amplifier

REFERENCE 150 SE Stereo Amplifier

Simply put, the REF150 SE is a breakthrough in stereo power amplification. Replacing the REF150—which was one of the most respected modern stereo amplifiers—was a daunting task, but it has been accomplished. The REF150 SE offers more power, greater dynamic thrust, a more vivid and resolved presentation, greater finesse, and quieter operation. It is the new benchmark. Having identical outer dimensions as its predecessor, the REF150 SE has much more packed into its chassis. Refined front-panel cosmetics reflect the updated look of current-generation models, with silver units having silver handles and silver top covers, while black units have black handles and black cover. (Colors may be mixed to match older models.)
