After we completed the design of our flagship Reference monoblock power amplifiers, we created a need for a preamplifier with the same features and sound quality. We came up with a preamplifier design worthy of that series, the Reference PRE. Made with the care and attention detail that characterizes all products from Unison Research, the Reference PRE preamplifier is truly another milestone in audio reproduction.

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.

A speaker who focuses the technology and know-how of the top models in the range Opera.

The Malibran model is the first speaker designed by Opera and marketed under the trademarks Unison: a passive speaker of very high quality and acceptable size for the home, with unique qualities to the limits of the holographic reconstruction of the sound event.

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.

This new loudspeaker model from Unison Research model is designed to be matched, in particular, to the Unison Research valve amplifiers. For this purpose both the sensitivity ando the impedance were optimized. The Unison Research Max It is a two-way floorstanding reflex-loaded system, with substantial internal volume despite a compact footprint.  The two reflex ducts fire forward, making it easier to place the diffusers in the room. This speaker can also be used as front channel in home theater systems; with two pairs of diffusers (front and rear) you get an high-impact home theater presentation that does not require a center channel or sub-woofer.

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.

UnicoDM is a hybrid dual-mono power amplifier design that is the perfect mate for the Unico PRE preamplifier, although it will blend seamlessly into most high-quality audio systems. Compared to the previous model of the same name, the new Unico DM features more than just a facelift. We wanted to substantially improve the unit in its most important design parameters, and the current version is more robust and powerful than ever before.

Many of our loyal Unison Research customers requested that we create a tube amplifier capable of output power well above all our previous achievements. To address this need, the design team created our flagship Unison Research amplifier, the Reference monoblocks. This amplifier is truly the culmination of all of our experience derived from years and years of valve amplifier design.
