The original Phono One was one of the most popular Unison Research products in our history. Its production was discontinued a few years ago, but the requests to bring it back were overwhelming. That’s why we’ve introduced its return, with a new and improved design. The aesthetics of the Phono One is unchanged, however, maintaining the classic and timeless look of the original version. The Phono One, from its beginning, was designed for those who require a phono preamplifier that offers the highest possible sound quality.
Three amplifiers symbolize the success of Unison Research: the Simply Two, the Triode 20 and the legendary Absolute. On the occasion of the 25th anniversary of the birth of Unison Research, we pay homage to these historic devices by offering the Simply Two and the Absolute in a limited and numbered “Anniversary” edition. We’ve also decided to offer a completely new version of the Triode 20 and named it, quite appropriately, the Triode 25.
The Unico 150 amplifier has been designed to suit both high-end audiophile and highly scientific criteria. This dual-approach to development has led to the creation of a product that is different to anything Unison Research – or any other manufacturer – have developed before: a powerful, great-sounding amplifier with only three stages (two tube stages and one power MOSFET stage).
Unico 90 is a class AB hybrid integrated amplifier with zero feedback, as the most precious valve amplifiers uses only two stages. The heart of the Unico 90 circuit is found in its hybrid structure. All of the gain, and subsequently the "character" of the amp, is determined by the only tube stage made with ECC83 and ECC 81in particular multiple-parallel-totem-pole.
Unico Due is the latest amplifier from Unison Research. Unico Due benefits from Unison Research’s decades of experience in design and production technology. It maintains all the best qualities that made its predecessor a runaway success and introduces new and enhanced features.
The Unico CD Due brings Unison Research right into the popular and versatile digital audio world.
Not just a CD player, the Unico CD Due combines a high-level DAC with a top-end CD mechanism. It’s feature-rich, flexible and customizable to the listener’s preference. A variety of external sources can be connected to the Unico CD Due, including a laptop or computer for playing all known audio formats – including DSD – via USB.
The new Callas Diva model is a three-way floor standing speaker that replaces the previous model with the same name. It has been completely redesigned. The performance of the new Callas Diva is at the level of the Grand Callas model but with a significant reduction in volume to be use in smaller room.
The Rotel RSP-1576 has been custom designed and engineered for music and movie lovers alike. This Surround Sound Processor includes the latest in audio and video technology including HDMI 2.0 4K/UHD 60Hz HDR video, Audio Return Channel, aptX CD quality wireless streaming and dual Texas Instruments DSPs supporting Dolby Atmos and DTS:X.
RAP-1580MKII is the ideal home theater solution delivering uncompromised performance packaged in a size efficient chassis that rivals many separates theater component installations. It is an ultra-high-performance multichannel-integrated amplifier supporting DTS:X and Dolby Atmos 7.1.4 surround processing bringing music and movies to life in stunning clarity. The amplifier section is built upon a powerful Class AB design driving all 7 channels simultaneously at 140 watts per channel into 4 ohm speakers loads, anchored by a massive Rotel factory-made toroidal transformer.
The RA-1592 MKII 200 Watt Integrated Amplifier skilfully leverages the strengths of Rotel’s award winning preamplifiers and power amplifiers in a sleek single chassis design. With a new DAC section and upgraded components in key areas inspired by the acclaimed Rotel Michi series, the RA-1592 MKII has been engineered to provide high-resolution audio performance combined with enviable versatility.
The Rotel RA-1572 MKII 120 Watt Integrated Amplifier is an affordable ‘Super Integrated’ that cleverly leverages the strengths of Rotel’s award winning preamplifiers and power amplifiers in a sleek single chassis design. With a new DAC section and upgraded components in key areas inspired by the acclaimed Rotel Michi series, the RA-1572 MKII has been engineered to provide high-resolution audio performance, yet it is very affordable, as has been the tradition with Rotel electronics for over 50 years.
The Rotel A14 MKII integrated amplifier takes all the functionality of the original and adds a fully redesigned Digital to Analogue circuit topology utilizing a Texas Instruments 32-bit/384kHz DAC with exhaustive tuning and hand selection of all critical components delivering a fuller, richer and more balanced presentation of the music.
DS Audio’s E1 entry level optical cartridge, achieves a performance level well beyond expectation and price range. The sonic qualities and resolution far exceed what one normally associates with an elliptical stylus and aluminum cantilever.
The DS003 cartridge is a completely new design. The third generation of DS Audio’ s optical cartridge features a comprehensively re-designed optical system that provides the following improvements and benefits:
We have further developed the optical cartridge system by implementing independent LED’ s and photo-detectors (PD’ s) for the left and right channels. The result is that the cartridge output voltage is dramatically increased from 40mV to 70mV (a 75% increase) and channel separation is greatly improved
The DS-W2 is an ‘optical generator’ cartridge with a number of trickle-down technologies first implemented on the company’s flagship Master1 cartridge – “Emulating the Master” as DS Audio states. In the DS-W2 the optical ‘screen’ has been placed in close proximity to the stylus, a strategy that is said to provide better photo-electrical efficiency or conversion, and a higher level of information accuracy pulled from the vinyl’s grooves. Further groove-tracking improvements are via the DS-W2’s boron cantilever and re-engineered ‘Micro-Ridge’ stylus which is claimed to be an improvement over the DS-W1’s Shibata stylus, itself a highly-regarded stylus design. DS Audio has included an aesthetic feature in the handcrafted ‘Natural Rose Quartz’ LED indicator.
The flagship of the DS Audio product lines, the new DS Master1 optical cartridge features the improved optical-mechanical design, wire-suspen sion, Sapphire cantilever and the micro-ridge stylus. The Master1 preamp/equalizer has the fully independent dual-mono discrete circuits with the single-ended RCA and balanced XLR outputs, as well as three low frequency cutoff points.
