TRIGON ENERGY – the new definition and consequent implementation of a classic concept. The result is an integrated amplifier which combines all the advantages and typical attributes you expect of Trigon preamplifier and amplifier combinations as well as sets new standards in its class. During an intensive period of development, a number of concepts, apparently promising but not entirely convincing, were tried and discarded since they did not have the cutting edge that was needed to design a Trigon integrated amplifier. 

The Unison S6 integrated amplifier offers personality, refinement and aesthetics...and a totally new amplifier design from a mechanical standpoint. The latest version of our S6 has been steadily updated and improved over the years to the point where it is easily one of the most respected integrated amplifiers in the world. The contrasting highlights of the wooden inlays on the front panel also reveal the technical sophistication of this amplifier, emphasizing the pride of ownership that comes with the term “Made in Italy.”

We’ve taken what we’ve learned from designing our largest amplifiers, and applied to this small yet brilliant gem. The Simply Italy integrated amplifier builds on the legendary strengths of the Unison Research Simply Two, one of the most successful integrated amplifier designs in the world. This new integrated amplifier, thanks to more efficient engineering, provides better sound quality as well as better reliability and tube life.

Bringing an evolved and expressive Class A sound to the peak of integrated amplifier

Class A 20W+20W, Class AB 250W+250W @ 8 Ohm

The attraction of the L-505uXII is its new level of refinement, approaching perfection as an authentically desirable product

Jeff Rowland Design Group is set to launch the 1500 WPC Daemon Super Integrated Amplifier at the Munich High End show May 12, 2015 - MOC A4 1.OG E114. Named after the ancient Greek word for the power of “creative genius” and the spirit of “scientific inspiration”, the Daemon represents a technological leap forward as Jeff Rowland’s fifth generation of integrated amplifiers.

A perfect example of Italian style and design, the innovations contained in the Unico integrated amplifier designs are universally appreciated and recognized.

The Primo is a stereo integrated amplifier that offers elegant lines and details, thanks to carefully considered surface finishes and proportions. Solid construction, careful selection of components and precise assembly are part of an almost artisan approach to amplifier design, reflecting our origins in Treviso. Unison Reasearch has concentrated all of our experience, knowledge and ambition into a small amplifier—one that includes all the technology and passion that one usually finds in the finest flagship products.

Like any self-respecting new heir to the throne of high quality integrated amplifiers, the Unico Secondo aims to collect and concentrate all of our experience gained in the design and production of its predecessors. A result in the endless quest for the highest standards of quality, the Secondo presents a new aesthetic without losing those characteristics that have been appreciated worldwide. Attractive and in line with current aesthetic trends, the Secondo is made with astounding attention to detail.

Part of our classic line of tube amplifiers that include the Sinfonia and the Performance, the Preludio integrated amplifier continues the technical approach, sound and aesthetics of its larger siblings. While the Preludio’s appearance is certainly gorgeous, it is also extremely reliable due to its unique design solutions, quality materials and adherence to the highest of standards.

Part of our classic line of tube amplifiers that include the Preludio and the Performance, the Sinfonia integrated amplifier retains the technical approach, sound and beautiful aesthetics found in the rest of the line. While the Sinfonia offers both stunning looks and equally stunning sound, it is also extremely reliable due to its unique design solutions, quality materials and the highest of build quality standards.

In the twenty years we have been designing and building audio products, we have always listened to the concerns and comments of our customers worldwide. We realized that over time, those customer needs have changed. In response, we have given a different look to many of our products, and we’ve updated some of our most classic and beloved designs. The latest version of the legendary Performance integrated amplifier offers increased power while staying true to the look of the original—an icon of rare elegance and musical pleasure.

The latest version of the classic S9 integrated amplifier offers more power and a new aesthetic form, all without sacrificing its impressive tonal characteristics or its strong performance to price ratio. The result of our extensive experience in the design and manufacture of integrated amplifiers, the S9 is the perfect symphony between these both of these elements. The output stages of the S9 are similar to its predecessor, but the functional aesthetics and the use of different tubes take the S9 to a new level of performance.

The popular American magazine The Absolute Sound first picked the Absolute 845 as the best product of 1994. After more than 20 years, the Absolute is still ranked first overall in tube amps with a score higher than any other amplifier. No other audio product has remained at the top of its class for so long. The Absolute 845 is not only the story of Unison Research, it is a significant piece of audio history in general, forever tied to the world of analog valves. In many ways, the Absolute is still unsurpassed.

This integrated amplifier sets a new benchmark in significantly narrowing any perceived performance gap between separate components and integrated amplifiers. Advanced technologies and real-world testing combine to create the INT-60 which presents 60 glorious watts per channel into 8 ohms, and doesn\'t leave class A until 30 watts thanks to its high-bias operation. This larger class A operating envelope brings lower distortion and greater loudspeaker control, delivering higher quality musical fidelity for your enjoyment.

Like the INT-60, the INT-250 utilizes the synergies developed in the .8 series power amplifiers. Unlike the INT-60, however, it brings 250 watts per channel of listening pleasure. With higher power MOSFETs and more of them, the INT-250 drives large, demanding and relatively inefficient loudspeakers at higher volumes without batting an eyelash, singing beautifully. Just incredible music from one component.

Marantz PM5005 Integrated Stereo Amplifier offers current feedback architecture for very fast and accurate signal handling and enhanced performance with an optimised discrete audio circuitry and fine-tuning components. The PM5005 offers 40 Watts at 8Ω or 55 Watts at 4Ω.
