Unison Research Secondo Integrated Amplifiers

Unison research secondo integrated amplifiers .

Outstanding integrated amp. Conseravatively rated at 100 wpc. Great build and aesthetics. Full, rich sound (tube preamp) without a touch of shrill notes. I thought it was cleaner sound than Rotel and NAD products at this level. Italian made and the beauty (including a solid wood remote) show the outstanding build quality. See http://www.tech.co.uk/home-entertainment/hi-fi-and-audio/hi-fi-amps-and-receivers/review/unison-unico-secondo for a fuller review.

USER REVIEWS

I have owned several good integrated amps I bought this based on reviews.The worst by far compared to any I have used in this price range.Very poor dynamics and really flat sounding.Very disappointed I bought an Audio analogue Maestro at a good price which kills this amp.If you are on a budget consider the Plinius 8200 vastly better.

Noisy lifeless and overpriced.Good build quality

After rolling tubes through it and settling on Telefunken 12ax7s, The soundstage on this monster widened and deepened. The balanced inputs are HUGE to the sound and the imporved transformer offers a more powerful and quieter alternative to the Unico (which I owned previously) and Uniso SE offerings. The wood remote is classy and just feels good in your hand. Con: they could have made a cage on the top for rolling tubes so that you wouldn't have to take the whole top of the cabinet off. Pros amazing air and detail. Excels at Vocals, but drove my speakers so well I often was asked where the sub was located . . .

Amazing power and sound quality. Absolutely brilliant sound.

Unison Research Seconda review

Not a true all-rounder, but its superb way with singers makes the seconda worth a second look tested at £1200.00.

unison research unico secondo

What Hi-Fi? Verdict

A must-listen proposition for anyone who revels in a vocal performance, but fractionally off the pace overall

Hefty build, nice remote

expansive and communicative sound quality

Some low-end ponderousness

‘Seconda': so much more evocative than ‘2' or ‘II', isn't it? And as Unison Research is Italian, such naming for its Unico integrated amp update isn't even pretentious.

The first thing you notice about the Seconda is that it's got taller: it's like an amp with a loft conversion. Also increased is the power – 120 watts per channel now lurks underneath that chunky casework.

In every other respect, it's as you were. There's a high-quality moving magnet or moving coil phono stage, and an eye-catching metal/wood remote, but no room for unnecessary fripperies such as a headphone socket or tone controls.

Let it get up to speed Once turned on (and after about 20 seconds to get the valves up to temperature), the Seconda offers a typically Unison sound. Clap Your Hands Say Yeah's Arm and Hammer is delivered in rich, full gobbets, the low frequencies slightly languorous but freighted with solid impact. It attacks manfully and deals with dynamic shifts with ease, while creating a credible soundstage.

Also in true Unison style, this amp's midrange is the real star – vocals, in particular, are beautifully detailed and utterly believable.

The Seconda's shortcomings are also familial: a slight lack of drive at the low end; not the cleanest entry into or exit from bass notes; and an inability to snap through hard-charging tunes like its best rivals.

So, it's not a true all-rounder, but its superb way with singers makes the Seconda worth a second look.

Hi-fi companies are a funny lot. As the Unico Secondo's maker demonstrates, they can produce a nice new amp... and forget to put it on their website, surely most people's first port of call for information these days.

Luckily, Unison Research's UK distributor is more alert, and from it we learn that this is the "second generation" of the Unico, a well-established valve/transistor hybrid design from Italy.

Not for the first time, we find ourselves wondering just how much 'valve character' one really gets from one double triode small-signal valve per channel, but, well, we've had good results from Unico models in the past...

It's a big amp and a well-filled case. The mains transformer actually looks quite small at first, but only because it's dwarfed by the case itself and the heat sink next to (and cunningly profiled around) it.

Moving across the case to the left, one finds a large rectifier and the usual reservoir capacitors, plus two pairs of MOSFET output devices per channel. Most of the audio amplification is done on a large board which carries the audio circuits (the valves and some ICs, a couple with their numbers intriguingly scratched off).

A daughterboard at the rear bears the selector switch, a mechanical type not accessible via the remote control, plus the input circuit for the single balanced input. The remaining five inputs are line-level unbalanced - one is upgradeable to phono operation.

Twin speaker terminals are fitted, plus phono outputs marked 'Monitor' (aka tape out) and 'Subwoofer' (pre out). We were particularly taken with the look of this model, with its extra-thick front panel - very aspirational!

It's a bit horses for courses, as ever, but this was clearly one of the hits of the day. One listener never quite found the levels of excitement he got elsewhere, for instance, but the others had little but good to say about it.

Most of all, they found in it the punch and immediacy thought lacking with some other contenders. Obviously, the Michael Jackson track benefited from this considerably, but it wasn't the only one to enjoy new-found life.

Some interesting direct comparisons were made with the RA combo (remember our panel were listening blind), the consensus being that this was probably the more neutral of the two contenders, but perhaps (as a consequence?) less upfront.

The Unico seemed to have more 'boogie factor' and perhaps slightly more impression of depth - and even, one listener suggested, height - in stereo images. It also seemed to have very impressive 'blackness' between notes, and some great dynamics too, not just in terms of swing from maximum to minimum, but also in the naturalness with which that was achieved.

Occasionally such qualities are achieved at the expense of analysis - not here. In fact, the Unico was superbly detailed, making clear the varied tones and directions of the instruments within the whole, but never separating them unnaturally.

If anything, sounds became more solid and real as they got more complex, with highly stable image placement and some very good depth too. And tonality? Well, given that not one listener mentioned the subject with any of the tracks, there can't be much wrong there!

Unison research unico secondo - £1,860.

unison research unico secondo

A large and imposing amp, this one is also pretty bare-bones, though unlike most it has the option of a phono stage. One of those was provided for review (the price given includes it, a very reasonable £125 on top of the basic model).

All kinds of amplifying devices are found inside the case, as the circuit uses bipolar transistors, FETs and valves. There’s very little use of surface-mount parts and most of the amplifying is done with discrete components, though there are a few op-amps dotted around and also some integrated circuits with part numbers intriguingly obliterated.

A substantial mains transformer is used and there is plenty of smoothing capacitance, plus quite extensive regulation of supply voltages for small-signal stages.

Uniquely in this group, input switching is done by a mechanical switch, mounted at the rear and operated by a long rod from the front panel – volume control also uses a regular mechanical potentiometer. The latter is motorised, but input selection is not remote controllable. That means you’ll have less cause to use the rather gorgeous remote, made of solid wood with a metal top plate – but also less cause to lament the ugly cheesehead screws which hold it together from the top. Please change to countersunk screws, at least!

Apart from the phono stage, input provision is basic and there are no modern frills like mini-jack sockets for portable players etc. There is a preamp output, which is also applicable to bi-amping and a record output marked ‘Monitor’. The phono stage handles MM and MC cartridges, though you have to get inside and fiddle with jumpers to change settings.

This turns out to be another amplifier that’s good at exciting, energetic music-making, though our listening panel did feel at times that it’s, perhaps, a bit too much of a good thing on the excitement front and could do with relaxing a bit. Specifically, it has a touch of brightness that affects voices, particularly the consonants and doesn’t always have quite a bass reach of the best in this group.

On the other hand, energetic rock and suchlike is great. Our Michael Jackson track went down well, helped by a big presentation and plenty of power and drive in the bass. The same qualities helped to some extent in our operatic excerpt, but in that case the excitement built at the start of one particularly long crescendo was rather undermined by the way the sound lost focus as more and more instruments and voices joined in.

Detail is better in less thickly textured music, but even in the unaccompanied choral track, which has only half a dozen or so voices, there was some lack of information about the acoustic of the recording venue, information that our listeners had heard through other amps. The voices themselves were very successful in this case, though, the rather more ambient recording making the Unico Secondo’s sibilance much less of an issue.

As the lone phono-compatible amp in this group it was hardly possible to make comparisons, but by the prevailing standards of decent integrated amps this one does a good job with LP sources, especially from moving magnet cartridges: moving coil is a little less clear. Bass is very clean and treble has a nice sense of cohesion to it.

WE SAY: A good phono stage adds value, but the sound could use a little more precision and less brightness. Good energy and lively, if not astoundingly extended, bass, while high treble has a pleasing sweetness too.

Ex Display Unison Research Unico Secondo Phono, Valve Hybrid Integrated Amplifier

Ex Display... Made in Italy... Unison Research Secondo Phono Valve Hybrid Integrated Amplifier in Silver.

The Unico Secondo draws on many years of knowledge and experience gained by Unison Research's technical team in the field of audiophile hybrid amplifiers. This new amplifier draws on the success of previous models, but also carves its own niche with the implementation of new advancements.  The power supply circuits have been improved with the addition of a secondary winding in the power supply transformer, effectively reducing power dissipation and increasing the overall reliability of the Secondo. The pre-amplifier and driver stages are based on the designs used in the coveted Unico SE and Unico 200 models, though they've been further refined through in-depth analysis, extensive technical measuring and long listening sessions. The use of two high-quality ECC83 (12AX7) valves brings the iconic Unison Research tube sound to the performance. While the Unico Secondo has undergone a careful and thorough restyling compared to previous models, it has not lost the distinctive elements of the Unico Series. The front panel has a greater height when compared to the Unico Nuovo and Primo, and the case-work is made from brushed anodized aluminum cover, which gives the amplifier a contemporary and more aesthetically pleasing look. The Unico Secondo can easily be integrated into a wide range of premium quality hi-fi systems. Together with the usual Line (RCA) inputs, the Secondo also boasts a balanced XLR input for higher-end sources. All models sold in the UK also benefit from a built-in MM/MC phono stage for easily connecting a turntable. The Tape Output and low-impedance Subwoofer Output (which attenuates with the volume control) means you can also integrate a dedicated headphone amplifier and expand your listening experience with a 2.1 channel speaker system.The supplied RC2 remote control adds convenience when controlling from your listening position. The aluminium front panels on all Unico series products are clean and stylish thanks to a new sandblasting and anodizing process. The sandblasting consists of hammering the the aluminium plate with microscopic ceramic balls at room temperature to give the surface a homogeneous and opaque finish. The anodizing process facilitates the growth of a thin film of aluminium oxide on the surface, which enhances the mechanical resistance and hardness of the surface. The end-result is truly stunning to help round off this prestigious piece of equipment.

  • Premium hybrid integrated amplifier
  • 2 x ECC83 (12AX7) valves
  • Easily becomes the centre of any high-end system

Unico due amplifier from unison research.

30th November 2018

unison research unico secondo

The Unico Due replaces the long-standing Unico Secondo in the line but brings new features to the range while also drawing inspiration from the Unico 90 design

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.  

Unico Due Amplifier From Unison Research

All based on 105μm tracks, the circuit board is fed by a power supply method that features a specially designed encapsulated transformer. The heart of the preamplifier stage is based around two ECC83 double triodes (one per channel). Configured as a gain stage followed by a cathode-follower, the circuit’s low output impedance drives the power stage.    The power amplifier stage itself features MOSFET transistors resulting in 100W per-channel output (8 Ohms).  

Unico Due Amplifier From Unison Research

Including a 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 32bit/384kHz PCM and DSD256. The integrated phono stage module is pre-set to accept Moving Magnet cartridges but can be modified by a service engineer to cater for Moving Coil devices. Additionally, the Unico Due has settings for AV passthrough, subwoofer output, DAC output, a Tape loop and to adjust channel balance. Price is £2,500.

For the first time Rosatom Fuel Division supplied fresh nuclear fuel to the world’s only floating nuclear cogeneration plant in the Arctic

The fuel was supplied to the northernmost town of Russia along the Northern Sea Route.

unison research unico secondo

The first in the history of the power plant refueling, that is, the replacement of spent nuclear fuel with fresh one, is planned to begin before 2024. The manufacturer of nuclear fuel for all Russian nuclear icebreakers, as well as the Akademik Lomonosov FNPP, is Machinery Manufacturing Plant, Joint-Stock Company (MSZ JSC), a company of Rosatom Fuel Company TVEL that is based in Elektrostal, Moscow Region.

The FNPP includes two KLT-40S reactors of the icebreaking type. Unlike convenient ground-based large reactors (that require partial replacement of fuel rods once every 12-18 months), in the case of these reactors, the refueling takes place once every few years and includes unloading of the entire reactor core and loading of fresh fuel into the reactor.

The cores of KLT-40 reactors of the Akademik Lomonosov floating power unit have a number of advantages compared to the reference ones: a cassette core was used for the first time in the history of the unit, which made it possible to increase the fuel energy resource to 3-3.5 years between refuelings, and also reduce the fuel component of the electricity cost by one and a half times. The FNPP operating experience formed the basis for the designs of reactors for nuclear icebreakers of the newest series 22220. Three such icebreakers have been launched by now.

For the first time the power units of the Akademik Lomonosov floating nuclear power plant were connected to the grid in December 2019, and put into commercial operation in May 2020. The supply of nuclear fuel from Elektrostal to Pevek and its loading into the second reactor is planned for 2024. The total power of the Akademik Lomonosov FNPP, supplied to the coastal grid of Pevek without thermal energy consumption on shore, is about 76 MW, being about 44 MW in the maximum thermal power supply mode. The FNPP generated 194 million kWh according to the results of 2023. The population of Pevek is just a little more than 4 thousand, while the FNPP has a potential for supplying electricity to a city with a population of up to 100 thousand people. After the FNPP commissioning two goals were achieved. These include first of all the replacement of the retiring capacities of the Bilibino NPP, which has been operating since 1974, as well as the Chaunskaya TPP, which has already been operating for more than 70 years. Secondly, energy is supplied to the main mining companies in western Chukotka in the Chaun-Bilibino energy hub a large ore and metal cluster, including gold mining companies and projects related to the development of the Baimsk ore zone. In September 2023, a 110 kilovolt power transmission line with a length of 490 kilometers was put into operation, connecting the towns of Pevek and Bilibino. The line increased the reliability of energy supply from the FNPP to both Bilibino consumers and mining companies, the largest of which is the Baimsky GOK. The comprehensive development of the Russian Arctic is a national strategic priority. To increase the NSR traffic is of paramount importance for accomplishment of the tasks set in the field of cargo shipping. This logistics corridor is being developed due regular freight voyages, construction of new nuclear-powered icebreakers and modernization of the relevant infrastructure. Rosatom companies are actively involved in this work. Rosatom Fuel Company TVEL (Rosatom Fuel Division) includes companies fabricating nuclear fuel, converting and enriching uranium, manufacturing gas centrifuges, conducting researches and producing designs. As the only nuclear fuel supplier to Russian NPPs, TVEL supplies fuel for a total of 75 power reactors in 15 countries, for research reactors in nine countries, as well as for propulsion reactors of the Russian nuclear fleet. Every sixth power reactor in the world runs on TVEL fuel. Rosatom Fuel Division is the world’s largest producer of enriched uranium and the leader on the global stable isotope market. The Fuel Division is actively developing new businesses in chemistry, metallurgy, energy storage technologies, 3D printing, digital products, and decommissioning of nuclear facilities. TVEL also includes Rosatom integrators for additive technologies and electricity storage systems. Rosenergoatom, Joint-Stock Company is part of Rosatom Electric Power Division and one of the largest companies in the industry acting as an operator of nuclear power plants. It includes, as its branches, 11 operating NPPs, including the FNPP, the Scientific and Technical Center for Emergency Operations at NPPs, Design and Engineering as well as Technological companies. In total, 37 power units with a total installed capacity of over 29.5 GW are in operation at 11 nuclear power plants in Russia. Machinery Manufacturing Plant, Joint-Stock Company (MSZ JSC, Elektrostal) is one of the world’s largest manufacturers of fuel for nuclear power plants. The company produces fuel assemblies for VVER-440, VVER-1000, RBMK-1000, BN-600,800, VK-50, EGP-6; powders and fuel pellets intended for supply to foreign customers. It also produces nuclear fuel for research reactors. The plant belongs to the TVEL Fuel Company of Rosatom.

Why were so many metro stations in Moscow renamed?

Okhotny Ryad station in Soviet times and today.

Okhotny Ryad station in Soviet times and today.

The Moscow metro system has 275 stations, and 28 of them have been renamed at some point or other—and several times in some cases. Most of these are the oldest stations, which opened in 1935.

The politics of place names

The first station to change its name was Ulitsa Kominterna (Comintern Street). The Comintern was an international communist organization that ceased to exist in 1943, and after the war Moscow authorities decided to call the street named after it something else. In 1946, the station was renamed Kalininskaya. Then for several days in 1990, the station was called Vozdvizhenka, before eventually settling on Aleksandrovsky Sad, which is what it is called today.

The banner on the entraince reads:

The banner on the entraince reads: "Kalininskaya station." Now it's Alexandrovsky Sad.

Until 1957, Kropotkinskaya station was called Dvorets Sovetov ( Palace of Soviets ). There were plans to build a monumental Stalinist high-rise on the site of the nearby Cathedral of Christ the Saviour , which had been demolished. However, the project never got off the ground, and after Stalin's death the station was named after Kropotkinskaya Street, which passes above it.

Dvorets Sovetov station, 1935. Letters on the entrance:

Dvorets Sovetov station, 1935. Letters on the entrance: "Metro after Kaganovich."

Of course, politics was the main reason for changing station names. Initially, the Moscow Metro itself was named after Lazar Kaganovich, Joseph Stalin’s right-hand man. Kaganovich supervised the construction of the first metro line and was in charge of drawing up a master plan for reconstructing Moscow as the "capital of the proletariat."

In 1955, under Nikita Khrushchev's rule and during the denunciation of Stalin's personality cult, the Moscow Metro was named in honor of Vladimir Lenin.

New Metro stations that have been opened since the collapse of the Soviet Union simply say "Moscow Metro," although the metro's affiliation with Vladimir Lenin has never officially been dropped.

Zyablikovo station. On the entrance, there are no more signs that the metro is named after Lenin.

Stations that bore the names of Stalin's associates were also renamed under Khrushchev. Additionally, some stations were named after a neighborhood or street and if these underwent name changes, the stations themselves had to be renamed as well.

Until 1961 the Moscow Metro had a Stalinskaya station that was adorned by a five-meter statue of the supreme leader. It is now called Semyonovskaya station.

Left: Stalinskaya station. Right: Now it's Semyonovskaya.

The biggest wholesale renaming of stations took place in 1990, when Moscow’s government decided to get rid of Soviet names. Overnight, 11 metro stations named after revolutionaries were given new names. Shcherbakovskaya became Alekseyevskaya, Gorkovskaya became Tverskaya, Ploshchad Nogina became Kitay-Gorod and Kirovskaya turned into Chistye Prudy. This seriously confused passengers, to put it mildly, and some older Muscovites still call Lubyanka station Dzerzhinskaya for old times' sake.

At the same time, certain stations have held onto their Soviet names. Marksistskaya and Kropotkinskaya, for instance, although there were plans to rename them too at one point.

"I still sometimes mix up Teatralnaya and Tverskaya stations,” one Moscow resident recalls .

 “Both have been renamed and both start with a ‘T.’ Vykhino still grates on the ear and, when in 1991 on the last day of my final year at school, we went to Kitay-Gorod to go on the river cruise boats, my classmates couldn’t believe that a station with that name existed."

The city government submitted a station name change for public discussion for the first time in 2015. The station in question was Voykovskaya, whose name derives from the revolutionary figure Pyotr Voykov. In the end, city residents voted against the name change, evidently not out of any affection for Voykov personally, but mainly because that was the name they were used to.

What stations changed their name most frequently?

Some stations have changed names three times. Apart from the above-mentioned Aleksandrovsky Sad (Ulitsa Kominterna->Kalininskaya->Vozdvizhenka->Aleksandrovsky Sad), a similar fate befell Partizanskaya station in the east of Moscow. Opened in 1944, it initially bore the ridiculously long name Izmaylovsky PKiO im. Stalina (Izmaylovsky Park of Culture and Rest Named After Stalin). In 1947, the station was renamed and simplified for convenience to Izmaylovskaya. Then in 1963 it was renamed yet again—this time to Izmaylovsky Park, having "donated" its previous name to the next station on the line. And in 2005 it was rechristened Partizanskaya to mark the 60th anniversary of victory in World War II.

Another interesting story involves Alekseyevskaya metro station. This name was originally proposed for the station, which opened in 1958, since a village with this name had been located here. It was then decided to call the station Shcherbakovskaya in honor of Aleksandr Shcherbakov, a politician who had been an associate of Stalin. Nikita Khrushchev had strained relations with Shcherbakov, however, and when he got word of it literally a few days before the station opening the builders had to hastily change all the signs. It ended up with the concise and politically correct name of Mir (Peace).

The name Shcherbakovskaya was restored in 1966 after Khrushchev's fall from power. It then became Alekseyevskaya in 1990.

But the station that holds the record for the most name changes is Okhotny Ryad, which opened in 1935 on the site of a cluster of market shops. When the metro system was renamed in honor of Lenin in 1955, this station was renamed after Kaganovich by way of compensation. The name lasted just two years though because in 1957 Kaganovich fell out of favor with Khrushchev, and the previous name was returned. But in 1961 it was rechristened yet again, this time in honor of Prospekt Marksa, which had just been built nearby.

Okhotny Ryad station in 1954 and Prospekt Marksa in 1986.

In 1990, two historical street names—Teatralny Proyezd and Mokhovaya Street—were revived to replace Prospekt Marksa, and the station once again became Okhotny Ryad.
