Unico Due

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 Due is a high-performance integrated amplifier that combines a valve pre-amplifier with a solid-state output stage for a class-leading performance that draws heavy inspiration from the flagship Unico 90 and Unico 150 models.

The electronic circuitry of the Unico Due has been completely redesigned from the ground-up. By working to the same brief as previous Unico models, Unison Research have introduced changes in the circuitry, the power supply method, the pre-amp stage, the power amp stage and with the variety of settings and inputs.

All based on generously sized 105µm tracks and using only the finest possible components, the circuit board is fed by a sophisticated power supply method that features a specially designed encapsulated transformer for increased efficiency and superlative sound. The heart of the preamplifier stage is based around two ECC83 double triodes (one per channel), which were purpose-chosen after hours of listening tests. Configured as a gain stage followed by a cathode-follower, the circuit’s low output impedance efficiently drives the power stage that follows for minimal electrical interference.

The power amplifier stage itself features a sophisticated implementation of MOSFET transistors resulting in 100W per-channel output (8Ω). The net result of which is a clean, powerful output with incredibly low levels of distortion. By reducing distortion so significantly in this stage, Unison Research have ensured that only the sonic character of the valves remain – staying true to the fundamental purpose of the Unico line.

The Unico Due stands out as a modern system hub not just thanks to its multiple line-level inputs, but also as a result of its built-in USB DAC and phono stage. The USB input features an ESS Sabre DAC ES9018K2M with jitter eliminator circuit, offering support for audio files up-to 32-bit/384kHz PCM and DSD256. Elsewhere, the integrated phono stage module is pre-set to accept Moving Magnet (MM) cartridges, but can be modified by a service engineer to cater for Moving Coil (MC) devices. Additionally, the Unico Due has settings for AV passthrough, subwoofer output, DAC output, a TAPE loop and to adjust channel balance.

The Unico Due is a powerful, easy to accommodate amplifier with a wide range of features and a sonic presentation that boasts all the benefits of valve technology with none of the shortcomings.

Key Features:

  • High-performance integrated amplifier
  • Hybrid technology combines a valve pre-amp with solid-state power stage
  • USB input for high-quality playback from a PC or laptop
  • Built-in phono stage for easy turntable integration
  • Powerful 100W output (8 Ohms)

Small hardcover: get the Kindle version instead
Format: Hardcover
This is a small format hardcover with 6.5 x 8.5 inch pages. As an armchair traveler I was hoping for more illustrations and I also found the small print, generally small photos and illustrations and the small captions on the illustrations quite frustrating. I would actually recommend the Kindle version instead since it is less expensive and allows you to better expand the illustrations to get a much better view. There’s a good description of eight of the more popular Caminos including the best known “French Way” which stretches almost 500 miles from the French border area to Santiago de Compostole in Western Spain. Learning about the history of the pilgrimage routes which stretches back more than 1000 years was interesting and the maps provide a good general sense of the different routes. The day by day accounts tend to be a bit boring without larger illustrations. This is a decent introduction for someone like me who only thought there was a single Camino de Santiago. Still I wish I had the Kindle version instead of the print version in this case.

Great Book for Choosing a Camino de Santiago Route with Distinctive Descriptions and Photos
Format: Hardcover
This DK travel guide is a little unusual in that it does not primarily focus on the things to see, places to eat, and places to stay, although brief suggestions are included. Instead, the book describes eight main routes of the Camino de Santiago in 2-to-3-day sections, plus some alternate routes and extensions, touching on the scenery and the history of the walk. Suggested cafes and albergues (pilgrim hostels) are relegated to small paragraphs that resemble captions. Arguably there are days when there won’t be much to see or do, just long meditative walks between farm fields or vinyards; also, the rigors of the walk may leave pilgrims too tired to explore much. As the guide says, “you’re not a vacationer, you’re a pilgrim.” Of course, there are helpful tips included, particularly in the back of the book where culture, etiquette, transportation, and training are discussed, but also some trail-specific advice throughout. For example, some routes like the Portuguese route allow for returning to the same hotel for several nights by utilizing trains to access different sections of the route. The distinctiveness of the various routes makes this a helpful book if you’re intrigued but not sure which of the routes would be right for you. You'll be left with a little more work to do to find contact information and seasonal operating hours for the listed places. The layout of the book features lots of pictures, as might be expected for a DK travel book, but the pages are not glossy and there are none of the cutaways and drawings which make DK books so recognizable. The book feels more like an engaging textbook than a typical travel guide. It seems to be an intentional decision not to carry paragraphs across pages, which gives the reader the opportunity to look at the pictures and captions before continuing. There are some artistic details like wavy-line swooshes that overlay the photos and unfortunately often make them look as though something is wrong with the print, but otherwise, the writing, design, and layout make the information very accessible.

Lovely book, tons of information and well organized
Format: Hardcover
This book has a cute retro feel to it, like something from the 70s or 80s that might have been lingering in the school library when I was a kid. Covers a number of different historical routes, broken down by starting point, with different lengths and duration. Each route is broken into managable chunks, with highlights on local foods and culture and sights to see along the way. Good information to help with planning- they do not recommend specific hotels/lodgings (such information could be quickly outdated) but do suggest which towns to stay in and whether or not you need to book there well in advance. They also call out some restaurants by name, well known for local specialties. In all, a very nice resource for anyone planning a pilgrimage and wanting to compare the different routes and learn more about the history.

Perfect size for me
Color: Light Color Series, Style: Waffle Pattern, Color: Light Color Series, Style: Waffle Pattern
Washed the cloths before use with just detergent. Pretty much stayed it shape and fluffy texture. It lathers well with any soap and drys fast. Love the texture size more than the exfoliating size. Texture side is great for sensitive face cleaning. The exfoliating side did soften after repeated use. I feel it is still little to rough for the face, but great for the body.
