The Enterprise is a monaural 300 watt power amplifier based on the Citadel, Theta's most powerful amplifier, and the Dreadnaught II. It benefits from the knowledge, research and dedication that team Theta brought to those superlatives designs. Enterprise has been created to power superb two channel music reproduction systems, as well as delivering abundant power to home theater systems, to fai...[more]

Jadis has adopted the KT120 valve, which will increase the power, reliability, the dynamic range and every other parameter of this milestone amplifier.Jadis has recognised that the brand-new KT120 expands on all of the virtues of the much loved KT88/6550 workhorses that have powered so many top-flight amplifiers. With their acceptance by Jadis, the doyen of French high-end amplifier manufacturers,...[more]

JA 500  An aesthetic look of parallels and diagonals. The JA 500 amplifier reveals a perfection of lines and its two blocks per channel respond to an unusual symmetry of forms and colours. When the eye follows the opposite diagonal, it is caught first of all by the black shape of the output transformer, then by that of the capacitors at the rear end of the other block. Black on blac...[more]

Listening to Reference 750 SEL monoblocks in a high performance system is a transformative experience; under total control, speakers disappear from the listening room and the listener is transported into a three-dimensional realm where music takes on a palpable, tangible form. Details from source material are resolved against a black background, painting images in space with vivid reality. Bass...[more]

Reference 160M Vacuum tube Monaural power 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 pr...[more]

SE 300B:  " ... grain , precision and dynamics..." " It gives an inimitable 'material' character to timbers without, however, allowing sounds to lose their musical character".  It has a "...special gift of revealing the intimate relations that link music to silence" - Jean-Philippe Delalandre and Alexandre Geoffroy. It "develops a sense of pace and rhythmical movement of such...[more]

SE 845: "an immense crushing breadth, a grandiose sound image which extends way beyond the bounds of the speakers and even of the listening room..." - Alexandre Geoffroy. The SE 845 amplifier uses the legendary 845 triode in a pure class A monotriode configuration. In this sense it follows the path traced out by the SE300B,which is to say, the search for un paralleled mus...[more]

The big change from the VT80 to the new VT80SE is upgrading the KT120 tubes to the higher performance KT150 output tubes. Everyone should know that we have been deeply enamored with the KT150 as we feature it in all of our other amplifiers, from the VSi75 to the REF 750SE. Its performance is unparalleled and its 3,000 hour average life allows years of uninterrupted listening. The VT80 was origi...[more]

Incorporating the best electronic elements of the original ProLogue Six and Seven, plus selected ground-breaking features from the more advanced DiaLogue Series, the next generation ProLogue Premium Series is an engineering marvel — a single pair of monoblock amplifiers that sets a new benchmark in high-performance audio with the following features: *Innovative, new Adaptive AutoBias ...[more]

The Reference 210 presents a familiar yet distinctive appearance. The chassis is enclosed, with a thick front panel the same height and width as the VT100/VTM200, but with a vacuum-flourescent display screen like the one featured on the REF3 and REF610T. The chassis is 19.5" deep (plus handles) and has an internal frame like the 150M, with a one-piece ventilated cover that wraps around the top and...[more]

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. From the moment the music begins, the foundation of an ex...[more]

The REF300 monoblocks have created as much of a stir among audiophiles and music lovers as the larger REF600s did when first introduced in late 1995. Well, we're happy to announce that REF300 owners now have good reason to be excited all over again with the introduction of the new and improved REF300MKII First, the sonic improvements embodied in the MKII version are nothing short of monumental...[more]

Following upon the technical changes that have been so successfully received in the MKII version of the REF300 monoblocks, similar changes have now been made to the design of the REF600 model. The resulting improvement in sonic performance is, if anything, even more dramatic in the 600-watt flagship model. As in the REF300, the REF600MKIII has been refitted with new audio and power-supply circu...[more]

When the Reference 600 Power Amplifier was introduced in 1995 it set a new standard for High Definition® in music reproduction. In every meaningful category, the Reference 600 - 300 amplifier series remained at the pinnacle of audiophile performance. Now the REF600-300 legacy continues with a new flagship from Audio Research: the Reference 610T monoblock.     Like its pr...[more]

The Reference 750 SE monoblock amplifier continues the story begun 20 years ago with the introduction of the Reference 600; that is, to create the ultimate, tube-driven amplifier with enough power to drive any speaker load and to provide a musical experience unlike any before it. The Reference 750 SE redefines all expectations of what is possible from an amplifier in a music playback system....[more]

First, you will notice a more modern, monochromatic appearance, including a new front panel with a small aluminum power button: natural units include silver handles and top cover, while black units come with black panel, handles and top cover. A new analog meter replaces the vacuum-fluorescent digital display of its predecessor; this illuminated meter is capable of displaying power output, line...[more]

The appearance is more refined and attractive, but is clearly a statement piece from Audio Research. A new, optional 12V fan-cooled silver top cover is available at additional cost.   Using the now-standard KT120 output tubes (8 matched pairs, driven by another matched pair) in the classic Audio Research push-pull Class AB output stage, the input stage has been streamlined, using very low ...[more]

Its purpose is to provide the differential signal for true balanced operation, a first for this series. With both balanced and single-ended inputs (switch selected), the VM220 will be compatible with every Audio Research preamplifier. In addition, the VM220 uses a super-wide-bandwidth output transformer to provide better frequency extension, explosive musical dynamics, and more powerful bass ex...[more]

The Valve VTM200 vacuum tube stereo power amplifier is the most powerful of the three Valve-series models. Rated at 200 watts per channel into a wide range of speaker loads, the Valve VTM200 encompasses a "dual mono" circuit layout reaching back to the massive single power transformer. Eight matched pair of 6650C output tubes and 674 joules of distributed energy storage give the Valve VTM200 unwav...[more]
