Unison Research Unico P

The Voodoo You Do!

Apr 12, 2009

Here are some of my thoughts on the Unico. Unison Research Unico P System used for audition: Rega R5 speakers Rega Apollo cd player Rega P3-24 turntable w/Dynavector 10x5 All van den Hul cables. I’ve been living in my usual state of audio dissatisfaction for quite sometime. I enjoyed my all Rega system but something has been lacking. It felt kind of gray or uninteresting to me. I’ve tried various speakers without enhancing my overall level of happiness…oh sure one speaker had better imaging or better bass response but in the end it wasn’t long before I was reaching for the old familiar R5’s. So now what…can’t afford any new gear and I really, really don’t want to make another lateral move….oh well, live with it. Then enters the Unico P. So I’m talking with a friend of mine who is familiar with my gear and he says “it ain’t gonna improve until you bid farewell to the Mira 3”….but I love my Mira 3, it matches my Apollo and has a fabulous phono stage…”so be it”. So I’m browsing a used HiFi store’s online inventory when I see this Unico P for less than I figure my Mira 3 is worth…hmm, I’ve heard good things about those…I wonder. I shoot ’em an email and his reply was; “Thanks for your email. We were listening to the Unico on Saturday and heard a distinctive hum in both channels so I am going to have my technician check it out this week. If it get's a clean bill of health, I'll email you right away. For now, I'll remove it from the website.” Thus began the saga of the great transaction…a couple of days later it was; The Unison is in the hands of our best surgeon right now. I think a tube simply went but we want to check the bias and make sure everything it okay. It will be 2 weeks until it's available again as he wants to test it under extreme hot and cold temperatures. Sorry for the delay. Hmm…so I waited 2 weeks and called….”I’m sorry but our tech has been out with personal issues…” oy vey! Finally and at long last I got the call, “we’re shipping it down for your audition” Yippie! Moments of disappointment quickly turn to excitement, followed by disappointment, followed by excitement and finally contentment. When I arrived home from work last Thursday (½ hour early…I was fortunate enough to have a power outage at work) there sat a box on the front porch…Unico Research clearly legible on the box. Excited as I was I had promised my wife and that we would go to dinner with her daughter and granddaughter. So I slipped the box into the house and split. Two long hrs later I was ready to start the listening. It took me all of 10 minutes to switch out the amps and prepare for listening. Disappointment First impression was that of a rather warm presentation but a bit dense with poor imaging but decent timbre. It had promise but that promise wasn’t realized yet…then I remembered a review I read while waiting for the unit to be repaired. The reviewer stated; “This amp scored a clear hit with all our listeners. It seems to have ticked all the boxes, and what's more the impression it made started well but got better. The praise began cautiously, with a warning note about slight veiling, but by the third track comments were uniformly positive.” http://www.techradar.com/reviews/audio-visual/hi-fi-and-audio/amplifiers/unison- unico-p-278302/review So I felt that some patience might be rewarded…but dadburnit patient I’m not! Excitement As the first evening wore on the amp sounded better and better. I was very impressed by now…however I had no idea what was to come. Night number 2..by Friday night the unit had been on 24 hrs and it was time to begin listening to music that has been giving my system a hard time. Music that I enjoy but that requires something special to really bring it out. What I was expecting to do is listen for sibilance, brightness, timbre, soundstage, imaging and all of those other audiophile goodies….what caught me by surprise was something altogether unexpected. Remember this if nothing else about this amp…it communicates music and it flat boogies. This reminds me of what Frank Abela said long ago about the Mira 3, it has pace and timing but lacks Rhythm when compared to Naim…uh yeah and now compared to the Unico P. The sense of rhythm that I experienced with the Unico is part of another phenomenon with this amp that blew my mind…it’s ability to articulate every line in a piece of music and weave it together where it all makes sense both individually as expressions of an artists ability and together as a coherent piece of art. Music that I liked before I now love as I can hear and more importantly feel all of it. I can now follow all of the lines in a piece of music while still tapping my toe to the overall piece…what a joy! A great cd to listen to to feel what I’m talking about is the Luciana Souza’s Brazilian Duos disc. When it’s right she sounds dynamic with an incredible ability to communicate, her voice like the body of a gymnast moves with speed and cat like precision and her timbre is rich. Lucinda Williams often sounds sibilant and her lyrics brilliant but a bit difficult to understand…not with the Unico P. Late night listening Friday to Lucinda’s World Without Tears cd revealed and amp that is able to convey the difficult emotions that are always a part of Lucinda’s music. Her lyrics were easy to hear and better yet to feel and the music made sense as part of the whole I didn’t leave vinyl out….I tried one of my favorites..don’t laugh…The Ozark Mountain Daredevil’s It’ll Shine When It Shines. I turned the volume up so that it was like one of my summer late night listening sessions and it sounded fabulous. Rich and warm with plenty of detail. In this area alone it was not a lot better than the Mira 3 but was at least as good. Oh yeah and I guess I forgot to mention bass extension and hi end and all of that, so what. It’s excellent but that is so much not the point with this amp. It’s all about musical communication…that’s what’s important isn’t it?! Diasppointment Hum…oh no, I HATE HUM!!! Wait a second…don’t panic.. So how much hum? In a quiet room you have to put your ear within’ 18 inches or so to hear it. But is it just mine, is there something wrong? No. I emailed other owners and they stated that they too have the hum and that it bothers them not a bit. OK…keep in mind that I’m trading my 2 year old amp that has the same retail value as this amp…and did ya read other comments here, ya I’m keeping’ it! Excitement The next day I start to play my favorite music and…no you’re kidding…it sounds better yet. Holy smokes how long can this continue? Honestly I don’t know. Everyday it sounds better, it hasn’t been turned off since I first fired it up. It just keeps getting better and better. By now as you may have guessed I've boxed up the Mira 3, thanked it for 2 years of unfailing service, and bid it farewell. Contentment That’s where I’m at today. Content in the fact that every piece I play sounds like music, real music. It’s a process of rediscovery as every cd I play sounds better than I’ve heard it before. Well that’s about it, sorry not much in the way of audiophile stuff. Just an emotional journey for me and one I’m glad I undertook. Thanks to all of my friends here at Ecoustics, Bill (Cableguy) from Audiokarma and Dale from Eugene HiFi. It’s been real…musical!

	Signore Giovanni "Diavolo" Sacchetti do it? No corner cutting on the insides either. Instead, techno-geek poetry and artful rather than terminal execution.
	[Photo of pre-production unit. The final appearance of the Unico CD's front baffle will likely be a bit different and the nomenclature silk screen may change size and placement.]

	keys, but the review will take you on a passenger-seat joy ride nonetheless. But first, final operational notes before I fire 'er up. With the aft power switch flicked, the unit undergoes a 20-sec thermal stabilization phase during which both small green LEDs up front flash furiously and the volume control should be set to mute/zero. When the lights go solid, the sonic curtain rises - unless the LEDs should flash again. That would indicate thermal protection and result in intermittent auto shotdown until the condition has passed or been remedied. Unwitting mains interruption or brief power failure will automatically trigger the start-up cycle once AC flows again. The Unico is further fitted with a loudspeaker short protection circuit whose internal jumpers JP16/17 can be removed for bypass if desired. The optional phono board replaces the standard AUX input and offers gain provisions for both MM (50-60dB) and MC (40-50dB) via clearly marked jumpers. +/- 10dB gain fine-tuning is possible by changing links JP102/10 on the board. MC input impedance is 100Ohm @ 440pF, the equivalent MM values are 47kOhm @ 220pf. RIAA equalization is compound passive/active, tolerance said to be within +/- 0.1dB. Ready for some window shopping?

Unison Research Unico Primo review

For an impressive performance, look no further than the unico primo integrated amp.

TechRadar Verdict

This is an amp that lives up to its billing and works brilliantly with the Unico CDE. Build quality, externally and internally – including the smooth-running controls (all two of them) and the twin sets of loudspeaker terminals – is excellent

An exceptionally well-sorted amplifier that gets the basic sound parameters just right, without straying off into valve-like excess

It has no obvious weaknesses, though you do have to pay a little extra for the phono input. The remote control isn't great, however, and there's no balance adjustment

Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test.

The Unico Primo is Unison's entry-level hybrid valve/transistor integrated amplifier and comes in a slimline housing with a finish closely matching that of the Unico CDE CD player.

In fact, the two can be stacked vertically with minimal heat build-up, since both are relatively cool-running.

The amplifier runs cooler than many solid-state models when idling and increased heat build-up when powered up is modest. The chassis is made from polished aluminium and acts as an effective heatsink, with louvres in the top panel adding increased thermal dissipation.

Design improvements

The Primo has a power rating of 85 watts per channel RMS into an eight-ohm load under all conditions, though Unison states that output is higher for non-correlated signals – that is, for anything but steadystate tones.

The model shares with its sister amplifier, the Unico P, a design based on a single double triode, in this case an ecc83/AX7 instead of the ecc82/AU7 combination used previously by Unison. This type of triode input stage is said to have quite different characteristics to the ecc82.

Apparently the choice arose from technical and listening-based investigations initiated by Unison technical staff, based initially on existing models in the company's range which were modified to suit.

Some improvements to the driver and power output stages have been made to suit the new input, with power-supply revisions including a larger, more powerful mains transformer and filter capacitor stage, with the intention of improving dynamics and bass-response drive capacity.

Amp connections

As standard, the Primo is a line-level amplifier, with a total of four line inputs and one tape circuit. But there are a couple of additional features that may be of interest.

One is the ability to convert a line input to an MM/MC phono stage, which will set you back a relatively modest £150 for an internal RIAA board – the phono input is already identified on the rear panel and is marked on the source selector.

If you don't choose this option, the input is a standard line input, one of the four already specified.

First-rate amplifier

Valve amplifiers aren't to everyone's taste, even if they can be easier on the ear and more relaxed-sounding than solid-state models. And it's fair to say that some early amplifiers in the Unison Research range fall into the ambivalent category.

But no such qualifications are required in this case. This is, by any standards (entry level or otherwise), a first-rate amplifier. For starters, it has an impressive power output. Not only does it go loud; it does so with some grace, and in particular it stays consistent in sound as the volume is turned up to quite impressive levels – tested on this occasion using a pair of Mordaunt- Short Performance 6 Le speakers.

It's that tell-tale hardening of the sound as the volume output is increased that makes many amplifiers stand out for all the wrong reasons. That said, in most respects, there's nothing obviously valve-like in the sound of this amplifier. It could easily be mistaken for a solid-state design, if you didn't know better.

It is, of course, solid state, in that the output stage uses MOSFETs, though they have the reputation of being the most valve-like of solid-state devices. But MOSFETs frequently don't live up to the stereotypes and lack a certain grace and transparency, which isn't an issue here.

The first thing we noticed was that the Primo is unusually solid-sounding, and it has this quality at virtually any volume level, within the limits established by its output stage. This is an amplifier with real grip, which became apparent in one of the early tests using a new recording of Benjamin Britten's War Requiem (Helmuth Rilling, Aurelius Sängerknaben Calw on the Hänssler classic label in PCM and SACD).

This was a real test in many respects, thanks to the way in which large orchestral forces and multiple choirs in the Requiem Mass are juxtaposed with a small chamber orchestra to partner the tenor and baritone soloists. Somehow, the Primo managed the clash of scales surprisingly well, and the result had a compelling unity of purpose, again with the solidity and consistency already referred to.

Another quality the amplifier brings to the table is an unusually fine bass. It's rich but pure and unerringly tuneful, as well as being essentially free of the romantic haze that persists with some valve amps. You can hear this from the start of Mahler's 7th Symphony (played by the LSO under Valery Gergiev).

This, like the Britten, is an SACD recording, or more correctly a multichannel hybrid recording, but it's a distinguished one that blossoms in high-quality DSD and therefore offers a performance level that's perfectly suited for this amplifier.

Impressive precision

The main qualities of the Unico Primo, then, are its generous output, its consistency with level, its tuneful bass and its ability to keep its act together when things become difficult and potentially messy – which is the danger with the dense and complex Britten recording.

In addition, the Primo is an amplifier with a strong sense of detail and precision, the kind that sounds close even when the system is in an adjoining room. In short, it's a class act. It's not exactly swimming in toys and gadgets, but everything necessary for a purist amplifier is there (though admittedly there's no balance control, which some might miss).

Other highlights include the ability to add a phono stage at a moderate cost and the fact that it can also drive a subwoofer in a 2.1 or 2.2 set-up. This is a very handy addition and one which should extend the amplifier's useful life beyond the point where it might otherwise be considered due for upgrading.

Awkward remote

The Unico Primo is also exceptionally well built. Though slimline, it still weighs a substantial 15kg, partly thanks to a massive toroidal power transformer, extensive use of die-cast heatsink extrusions and a thick one-piece front panel.

We're less impressed by the remote control, however, which looks fine at first sight, but is marred by prominent fixing screws on the top plate and by the controls themselves, which are tiny and awkward to use.

In its favour, though, this is the same remote that's supplied with the Unico CDE CD player, so you only need the one handset to control the entire system – leaving you one spare to lose down the back of an armchair.

Unison Research Unico 150 review

This powerhouse of an amp delivers a huge amount of fun too... tested at £4000.

What Hi-Fi? Verdict

The Unico 150 is something of a powerhouse. It delivers an immensely muscular sound mixed in with a large dose of fun

Muscular, energetic presentation

Strong dynamics

Fluid midrange

Lacks a little precision and insight

Some small build issues

Why you can trust What Hi-Fi? Our expert team reviews products in dedicated test rooms, to help you make the best choice for your budget. Find out more about how we test.

Unison Research’s flagship Unico amplifier is something of a beast, albeit one dressed in a crisp smart suit. The numbers reveal a lot about this hybrid integrated – £4000, 25kg and 150W per channel.

But even these take a back seat to the way it looks on our test rack. The Unico dwarfs most of our reference kit thanks to its generously stocky proportions.

That nicely finished casework measures a substantial 18 x 44 x 44 cm (hwd), so make sure you have plenty of space to house it. While the Unico doesn’t run particularly hot it’s still good to leave a decent amount of space around to help with ventilation.

MORE: Awards 2015 - best stereo amplifiers

Build quality is mostly good. The three-piece front panel is crisply machined and the rest of the casework feels immensely solid. Neat details such as the classy-looking RCA socket used and Unison Research branded speakers connections lift the 150 above the norm.

There’s a choice of finishes – the silver of our test sample, or black. The latter will cost you £100 more.

There are some areas where there is room for improvement. The two large control dials fit nicely in the hand, but the input selector feels a little wobbly. That three-piece front panel looks distinctive, but one of the trio of panels wasn’t aligned exactly. It was only a touch out, but at this price, Unison Research, we’d like perfection please.

Take a look inside the metalwork and you’ll find a dual-mono hybrid circuit, which mixes valves in the input and driver stages with MOSFETs on the output stage. It’s a clear attempt to blend the fluidity and finesse of valves with plenty of muscle and grip.

Many manufacturers have tried to combine these vastly different technologies and judging by the mixed results it isn’t easy to get right. Unison Research is one of the few to do so on a consistent basis.

That Class A/B MOSFET output stage is capable of plenty of power. It has a claimed output of 150W per channel into 8 ohms that rises to a mighty 220W as impedance halves.

That’s plenty of grunt and certainly enough to deliver high volume levels from most price compatible speakers.

The Unico’s connectivity is good enough for the types of systems it’ll typically be bought for. There are a decent number of line level inputs including a pair of balanced XLRs plus a direct connection that bypasses the volume control – for use in a multichannel set-up where the volume level will be controlled by an external AV processor.

There are two pairs of speaker connections to help make biwiring easier.

The distinctive remote got a mixed reaction from our test team. For the most part, we warmed to the oddly-shaped wooden casing, but the multitude of identikit small circular buttons didn’t fare as well.

It’s a system remote, which means the vast majority are no use for the amp, plus their slightly sharp edges didn’t meet with universal approval.

Once up and running, the Unico proves an impressive unit. We connect it into our reference system using Naim’s NDS/555PS music streamer as the main source with our long serving ATC SCM50 speakers completing the set-up.

In this system the 150 comes across as something of a powerhouse – no surprise considering its generous output.

Considering the amplifier’s muscularity, large-scale classical works seem a good place to start listening. We run through Tchaikovsky’s Marché Slave Op.31 and Stravinsky’s The Rite of Spring , taking in a large dose of Dvorak in the middle. The Unison Research is a smooth performer with a lively and articulate nature, though that isn’t what grabs our attention.

We are initially drawn to the presentation’s scale and authority. It sounds huge, with plenty of headroom and the ability to play at furniture rattling levels without any obvious signs of stress.

There’s little sign of hardness as volume level head northwards, just a wall of sound that extends to completely fill one end of our listening room.

MORE: Best stereo amplifiers 2016

Tonally, there’s a decent balance, though the top end lacks a bit of the body and richness that makes the bass frequencies so attractive. The Unico’s sound staging is nice and wide, but lacks a little depth compared to the best we’ve heard at the price.

We move onto Nick Cave’s Push the Sky Away and love the way the Unison renders voices. There’s delicacy here and the kind of fluidity that brings to mind some of the company’s all-valve designs. It makes a decent job of rhythms too, allowing the song’s gentle momentum to build with grace.

We know there’s more detail on this track than the Unico delivers and a greater separation of instruments too, but there’s enough this amplifier does right that such shortcomings don’t concern us.

That’s particularly the case when switching to Can’t Hold Us by Macklemore & Lewis where the Unison Research responsive nature makes listening to the song a treat. The amplifier’s energetic delivery works brilliantly. There’s so much drive, it’s exciting, impressively articulate and a whole lot of fun.

Fun is a thing many high-end products overlook in the quest for ever more insight and refinement – we’re glad Unison Research hasn’t gone down that road.

The Unico 150 isn’t flawless, but it is immensely likeable. For some the size may be an issue, other may want a more transparent and precise performer, but we’re charmed by its big-hearted presentation.

2016-10-03 6:55 am

Hello Guys, I need some help, I am new in this forum and tried in several ways to solve my problem. I own a Unison Research Unico P amplifier, the model with only single ECC82 tube, is actually my second Unico P. From a while I have a kind of pop noise (very loud) in the speakers, almost enough to damage them and I am afraid to use it anymore. The pop noise is totally random (no specific pattern), can happen after 15 min or few hours, with or without signal on the inputs. I changed the tube ECC82 with several others, NOS or new, but no success. I changed the tube socket with new one, I tried to check all solderings and re-soldered where I considered is necessary. Nothing. Defect still remains. I wrote to Unison Research technical support and they promptly replied and suggested to replace voltage reference TL431 clp which I did. Still no success. The issue seems to be related to both channels as long the pop noise appear in both speakers. That's why I decided to write you as being my last chance. You may have some clues or advice's to me that may help to solve the issue. At least will be great is somebody can help me specifically with service manual, unfortunately UR technical support did not provide it to me. Many thanks in advance

Which speakers for Unison Research Unico P?

I have a Unison Research Unico P, which I initially got because of my bookshelf speakers not having enoug warmth. I have paired it with Leema Xero speakers and I have a lot of warmth. I also changed the russian tube for a NOS and it is definitely clearer. However, there isn't enough weight in the sound. The speakers are at one end of a very long room (35fts), which is rather narrow (12fts). Although this amp is great, very few people have Unison Research Hybrid amps, so it is difficult to find infos on matching it with speakers. I am considering two options, although I would welcome any other suggestions too, to gain a more room filling sound option 1: Dali Mentor Menuet (because the are small, so would fit on my shelves, and seem to still be an upgrade to the Leemas) option 2: Spendor A5 (because they seem to be amazing while very small -- less than 80cm high and rather narrow -- floorstand speakers). I was also advised to use it with Sonus Faber speakers, whereas one of the forum members suggested it might be too soft a speakers given the natural softness of the amp. In summary: I need speakers which will not find ugly space absorber while deliverying precise and full of presence sound. Any ideas? Many thanks in advance. Alex

I think you should consider the Kef R Series, which have ample bass for their size.

CnoEvil, thanks for your suggestion. Although the speakers are a little larger than I was considering, I will add them in my listening session early next week. The 3-way system does indeed suggest a lot of presence. Many thanks again. Alex

Harbeth P3 ESR... a small speaker, but with a big sound and great precision. Mac

Macspur, Thank you for the advice. I had a look at the Harbeth P3 ESR and it is really small indeed. I will try it out. I am currently trying a Sonus Faber. The sound is very good, but I still can't get the sound to surround me and fill the room. I start wondering whether I am too demanding and have reached the limits of the amp, or whether floorstand speakers are the only solution. Working on that.

Hi, Thank you for the additional suggestions. I tried a couple of speakers over the week-end, and both worked very well. Both speakers were Sonus Faber, once was the Liuto Monitors which worked very well, was very precise, but lacked the bass I was hoping to gain from an upgrade (bass is still very good, but not as good as the next one I tried). I have then tried the Sonus Faber Toy Tower floor stands. This was very good. I actually discovered how amazing the Unison Research is and the power and details it has. Maybe marginally less details than the Liuto, but the presence is excellent. The standard version of the speaker comes in black leather, but the one I want, costs another £450. Total £1,850. If I have to spend that money, I was wondering whether there is any good competiton to the Sonus in the £1,800-2,200 bracket. By the way, I also had a look at the Harbeths, but these speakers are unfortunately too wide. I am happy to go up to 100cm in height and would definitely stay on floorstands.

If you like SF, often nothing else will do.......though I would still look at Proac, Spendor and Kef R series (as mentioned above). Let us know how you get on. Cno
