The push-pull circuit includes a final stage with two power tubes intended for the amplification of the positive half-waves, respectively, and of the negative half-waves of the audio signal. The task of properly reconstructing the audio signal is then assigned to the output transformer which, thanks to its symmetrical structure, allows for a highly linear signal.

Today’s amplification devices are not perfect— they basically distort as amplification stages are added.

This is the reason why structural simplicity is a coveted goal in amplifier design.\u003cbr\u003e\u003cbr\u003eOur research at Unison Research led to two circuit performance standards that are, to us, considered essential for excellent performance: a 3-stage circuit and a 2-stage circuit, both with zero global feedback.

The second type, used in the Unico 90, is a more effective application for medium-powered amplifiers.\u003cbr\u003e\u003cbr\u003eBoth of these approaches allow Unison Research to reach a standard of linearity that is almost impossible with the usual technologies that are matched to single-ended driving capabilities.

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-totempole. This stage is made with the six triodes for channel, and is configured so that they present limited gain with the least output impedance possible. The choice of the triode was determined by multiple factors during the development process although our testing and research made our ultimate choices rather obvious. These factors included the following:\u003cbr\u003e\u003cbr\u003eThe triode linearity of coupled, i.e. the mutual and automatic compensation of the nonlinearity of each.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe high linear excursion of the signal and the relevant current capacity of the triode output, necessary for driving the load constituted by the final stages and predominantly by the input capacitance of the complementary pairs of hexfet that are chosen.\u003cbr\u003eA gain stage triode that is equipped with its own ring of partial reaction, characterized by a factor of feedback very low (16 dB, which is between one-tenth and one ten-thousandth of the typical value adopted in similar circuit topologies) that serves mainly to obtain a very low output impedance without the slightest damage to the parameter “consistency.\" \u003c\/p\u003e\n\u003cp\u003eTransistors (bipolar or field effect that they are) and valves distort. But in terms of high order residues, valves are unsurpassed and allow invariant residues across almost the entire range of frequencies audible to the human ear. Many audiophiles speak of valves having a soft sound, and this feature is immediately identifiable on an oscilloscope. In fact, you can see on display the waveform of residual distortion of a valve circuit that the signal never changes that quickly, especially compared to the norm of almost all transistor circuits. When those valve circuits are in parallel, however, the measurement of distortion within the frequency of the input signal trend nearly flat.\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan\u003e\u003cstrong\u003ePower\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eWhen designing the Unison Research Unico 90, consistency was one of the primary goals. This consistency is maintained practically at almost every level of power delivery, with the partial exception of the eighth highest at maximum power (a condition that no actual audio signal may take). This is due to the linearity the first two stages of valves, and direct coupling between these and the MOSFET output. This innovative solution has allowed Unison Research to eliminate yet another stage present in virtually every other amplifier, thermal compensation, which in certain cases can be a direct or indirect source of distortion. The Unico 90 reaches nominal linearity in just a few tenths of a second, with optimal linearity optimal achieved in little more than 10 minutes.\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan\u003e\u003cstrong\u003ePreamplifier\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe preamp section of the Unico 90 also incorporates a number of innovative solutions. The preamp section is totally passive. Doing otherwise, of course, would have increased the number of stages in the circuit. An ALPS potentiometer is armored in four sections, parallel in pairs, so as to reduce the already minimal noise in order to further improve the precision of the channel balance, especially in the region of high attenuation. The selected sources are connected one at a time, lifting the mass from those not connected in order to interrupt the ground loops associated to the connections not used. (These could otherwise act as an antenna and reveal the electromagnetic signals present in the environment, in addition to generating crosstalk between the channels.) Switching is performed by purely mechanical miniature relays that are armored and placed behind the sockets. The terminals of the input not used are deflected toward their ground through resistors of suitable value to preserve integrity in order to eliminate the risk of capacitive coupling through the movable contacts. The balanced inputs are not obtained by electrical means, which would be considered a “fall back” solution, given the impossibility of obtaining symmetry on the terminals of opposite polarities. Instead, we use transformers which allow a truly balanced transmission of signals and galvanic isolation. In addition, this approach creates powerful aid against the ability to break down interference coming from anywhere else. Although optimized for this function, the use of these transformers may offer slightly worsen electrical performance at lower frequencies, particularly with sources where the output impedance is not low.

Its design is based on a balance of features, and altering it would involve sacrifices in certain directions. Increasing the number of MOSFETs, for example, would permit the use of loudspeakers with impedances of less than 2 ohms without altering the production cost significantly, but this would compromise that consistency and linearity across the high frequencies. We could have extended the frequencies a few tenths of a Hz, and it would have been very easy to do so, but it would have increased the overdriving of the inputs resulting in badly-digested tube power due to the potential positive effects of the grid.\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eCapacitors\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eAll capacitors \"touched\" by the signal are the types that exhibit very low loss and excellent behavior at high frequencies.

Even if the production of this item has been discontinued some years ago the request never stopped so we decided to renew and improve this design. Nothing has changed it the external looking since the original design was so nice and timeless that even after many years it has it’s untouched aesthetic appeal.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe circuit implemented has lots of features in common with the SimplyPhono, here one more tube has been used, bringing up to 10 the number of triode (i.e. 5 ECC83\/12AX7 double triodes). All of the gain stages are now implementing parallel configuration for the best noise and distortion performances. This solution increases also the overall gain to approximately 54dB, enough for all the MM and most of the MC cartridges. The same passive RIAA network has been adopted but with special selected components in order to ensure strict tolerance to the equalization curve. Increased value for the output capacitors improves bandwidth and phase rotation at low frequencies.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eIn order to avoid the problem of dc voltage and bump during the warm up and switch off time of the unit a delayed muting function has been implemented, this way the output is disabled till the tubes reaches they’re optimal temperature and working point at the switch on and prevent the loud bump at the switch off. While in SimplyPhono only the resistive component of input impedance is selectable here both resistance and capacitance can be matched to the requirement of any cartridge for best performances. A dedicated free location on the PCB allows the installation of custom value resistors in order to set the interface parameters even at any non common value.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eParticular care has also been dedicated to power supply design. In order to minimize cross-talk and inter-stage interference an independent RC filter cell has been placed near every gain stage, thus reducing the cross-talk (especially at low frequency) of more than 20dB in comparison with the extraordinary performances of SimplyPhono. In the new PhonoOne low frequency cross-talk is practically immeasurable, less than -90dB.

The Unison Research Simply Phono is simply that—an outstanding tubed phono stage that offers incredible performance for the price.\u003cbr\u003e\u003cbr\u003eAs can be easily verified there’s a renewed interest for vinyl in the hi-fi market. The Black Disk seems to catch the attention of a wider audience that the consolidated lovers it always could rely on.\u003cbr\u003e\u003cbr\u003eAware of this trend Unison Research decided to enhance its catalogue adding a new turntable + arm + cartridge system named Giro and to work on a new release of two of its standalone phono stages: SimplyPhono and PhonoOne.\u003cbr\u003e\u003cbr\u003eThe new SimplyPhono bears the same name and indeed shares the same appearance as its predecessors but thanks to a revisited circuitry and improved layout it exhibits noticeably better audio performances.\u003cbr\u003e\u003cbr\u003eAs its predecessor the new SimplyPhono is an all-tube phono preamplifier. All the stages work in pure class A and no global negative feedback neither local feedback is applied. It employs 4 ECC83\/12AX7 double triode (versus the 3 ones used in the previous release of the unit).\u003cbr\u003e\u003cbr\u003eThe tubes are arranged so that the first couple of triodes acts in parallel as a maximum gain stage implementing a particular configuration named “ionic bias” in order to prevent the cathode self-polarizing circuit from introducing unwanted local reverse-effects and with improved performances as regards noise and distortion.\u003cbr\u003e\u003cbr\u003eFor the RIAA equalization network a completely passive solution has been chosen after some listening test. The use of strict tolerance resistors and hand picked, measured and selected capacitors ensures a precision of 0.1dB of the frequency response.\u003cbr\u003e\u003cbr\u003eThe equalization network is followed by a second gain stage direct coupled with a cathode follower output stage as an optimal solution in order to achieve the needed overall gain and a low output impedance.\u003cbr\u003e\u003cbr\u003eParticular care has been put in the power supply stages. In order to maximize the dynamic response of the unit a high value for the anodic supply has been chosen. A particular circuit using a series power MOSFET and a precise voltage regulator ensures a stable low ripple supply voltage of more than 300V. A further filter feeds the second and output stages of both channel with a very stable voltage.\u003cbr\u003e\u003cbr\u003eIn order to minimize cross-talk and PSRR (power supply rejection ratio) in the first (and more tricky) gain stage a last couple of RC filters and a zener regulations has been implemented, one for each channel.\u003cbr\u003e\u003cbr\u003eAs usual for Unison Research technical staff, a great care has been dedicated to the design of the layout of the board. This is a key feature that is often undervalued but that can heavily affect the final result. A smart symmetrical design, outcome of a long dated knowledge, improved even more cross-talk and noise parameters.\u003cbr\u003e\u003cbr\u003eAs an example we can measure a huge improvement of cross-talk over all the audio spectrum with a reduction of 20dB at middle band frequencies.\u003cbr\u003e\u003cbr\u003eWith a gain that makes it suitable for all MM and medium to high level MC cartridges, with a noticeable improvement of sonic performances, with improved quality RCA connectors and input impedance variable setting the new SimplyPhono accentuates it already high value.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"496\" style=\"border-collapse: collapse; width: 372pt;\"\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"197\" style=\"mso-width-source: userset; mso-width-alt: 6888; width: 148pt;\"\u003e \u003ccol width=\"299\" style=\"mso-width-source: userset; mso-width-alt: 10426; width: 224pt;\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" width=\"197\" style=\"height: 14.5pt; width: 148pt;\"\u003eType\u003c\/td\u003e\n\u003ctd width=\"299\" style=\"width: 224pt;\"\u003eStereo Phono Valve Preamplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eClass\u003c\/td\u003e\n\u003ctd\u003ePure A class\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eRIAA\u003c\/td\u003e\n\u003ctd\u003ePassive +\/- 0.2 dB (20 Hz \/ 20 KHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eOutput Impedance\u003c\/td\u003e\n\u003ctd\u003e800 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eOutput\u003c\/td\u003e\n\u003ctd\u003e1 x line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eGain\u003c\/td\u003e\n\u003ctd\u003e52 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eTotal Harmonic Distortion (THD)\u003c\/td\u003e\n\u003ctd\u003e0.4 % at 1 volt output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eSignal to Noise Ratio (S\/N)\u003c\/td\u003e\n\u003ctd\u003e– 72 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e1 x phono cartridge MM or MC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e47 Kohm – 100 – 50 – 22 ohm \/ 100 pF (modifiable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eFeedback Factor\u003c\/td\u003e\n\u003ctd\u003e0 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eValves\u003c\/td\u003e\n\u003ctd\u003e4 x ECC83 \/ 12AX7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003eExternal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eDimension\u003c\/td\u003e\n\u003ctd\u003e140 x 290 x H 105 (mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"19\" style=\"height: 14.5pt;\"\u003e\n\u003ctd height=\"19\" style=\"height: 14.5pt;\"\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e3 Kg (including power supply)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Unison Research","offers":[{"title":"Default Title","offer_id":51268190798105,"sku":"1985newUnisonResearch","price":1999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/Unison_Research_Simply_Phono_Tube_Preamplifier_1.jpg?v=1769091767"},{"product_id":"unison-research-unico-nuovo-integrated-amplifier","title":"Unison Research Unico Nuovo Integrated Amplifier","description":"\u003cdiv class=\"product-description\"\u003e\n\u003cp\u003eThe Unico Nuovo, like the Unico Primo and previously the UnicoP, is an integrated amplifier that is based on a 'single triode stage per-channel' design. Where it carves it's own new territory is through using 2 x ECC83 (12AX7) valves with a new biasing solution and a parallel double-triode design. By doubling the number of triodes (compared to the Unico Primo) and employing a parallel configuration, the Unico Nuovo is capable of a more refined sonic performance than those that have come before.\u003cbr\u003e\u003cbr\u003eThe new biasing solution - based upon a design previously found in high-end phono stages, called \"ionic bias\" - involves the Unison Research-designed power supply working in tandem with the \"level shifter and signal follower\" stages that come after the triode stage to deliver an accurate, audiophile sound from this hybrid amplifier. This innovative layout allows for non-manual adjusting of the bias as the valves bed-in and age, to ensure a longer and more reliable performance.\u003cbr\u003e\u003cbr\u003eIn the driver stages, the output devices are fed by a symmetrical current mirror stage, made with bipolar transistors. This method allows for minimal phase displacement and a more valve-influenced sound delivery. The output devices themselves are Power MOSFETs laid-out symmetrically, and both receive power from the same power supply stage with a special configuration to ensure the required voltage is always delivered. In total, this design allows for greater channel separation and balance, higher efficiency and greater musical detail.\u003cbr\u003e\u003cbr\u003eThe Unico Nuovo is supplied in the UK with a built-in MM\/MC phono stage for simple connection to a turntable. The back-panel is also equipped with a low impedance stereo output for connecting to a powered subwoofer (or any other Line level input). The supplied RC2 remote control adds convenience when controlling from your listening position.\u003cbr\u003e\u003cbr\u003eThe aluminum 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 aluminum 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 aluminum oxide on the surface, which enhances the mechanical resistance and hardness of the surface.
