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. All listening tests conducted in the course of development, however, have confirmed the effectiveness of this choice, which was therefore maintained despite the significant increase in cost.\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Unico 90 is a dual mono amplifier with a single power transformer capable of delivering 600 continuously.

These circuits, of course, are protected and are weighted on 70% of their maximum specifications so to maintain an adequate margin of safety without affecting significant drive capabilities. The total transparency of the sound of these circuits is easily verifiable--they protect in real-time and can disconnect the load when activated by the intervention of a single half-wave signal.\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan\u003e\u003cstrong\u003eLoudspeaker Matching\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eUnico 90 can drive loudspeakers that are very challenging loads, but it is advisable not to choose extreme speakers with a minimum impedance of less than 2 ohms. 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.

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.

In the new PhonoOne low frequency cross-talk is practically immeasurable, less than -90dB. Also a careful layout design improving channel separation and interference rejection, together with an elastic suspension of the amplifier board helped bringing the sonic performances of the new PhonoOne to a supreme level of natural detail and musical clarity.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eAs imposed for a no-compromise design, all the supply voltage are regulated and heavy filtered.

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. The end-result is truly stunning to help round off this prestigious piece of equipment.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cspan\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eOutput Power: 95W RMS\/ 8Ohm\u003cbr\u003eFrequency response: -0.1dB @ 10Hz, -0.5dB @ 100kHz\u003cbr\u003eInput Impedance: 50kOhm \/\/ 47pF\u003cbr\u003eSensibility: 260mV RMS\u003cbr\u003eInput stage: Pure A Class, parallel Valve stage, ECC83\/12AX7\u003cbr\u003eOutput stage: Dynamic A Class POWER MOSFET complementary\u003cbr\u003eInput: 5 Line RCA (1 phono optional)\u003cbr\u003eLine Output: 1 tape, 1 sub (with volume control)\u003cbr\u003eOutput Connector: 4 + 4 bi-wiring\u003cbr\u003eFeedback factor: 10dB\u003cbr\u003eTHD: 0.15% @ 10W\/1kHz\u003cbr\u003ePower consumption: 400W max\u003cbr\u003eSize: 43.5cm x 9.5cm x 43cm\u003cbr\u003eWeight: 16kg\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"The Music Room","offers":[{"title":"Black (Special Order)","offer_id":51268252107033,"sku":"2001newUnisonResearch","price":3299.0,"currency_code":"USD","in_stock":true},{"title":"Silver","offer_id":51268252139801,"sku":"2000newUnisonResearch","price":3299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/Unison_Research_Unico_Nuovo_Integrated_Amplifier_1.jpg?v=1769092183"},{"product_id":"unison-research-sh-headphone-amplifier","title":"Unison Research SH Headphone Amplifier","description":null,"brand":"The Music Room","offers":[{"title":"Default Title","offer_id":51588781343001,"sku":"newUNSN0002","price":0.0,"currency_code":"USD","in_stock":true}]},{"product_id":"unison-research-simplyphono-power-supply","title":"Unison Research SimplyPhono Power Supply","description":null,"brand":"The Music Room","offers":[{"title":"Default Title","offer_id":51977393144089,"sku":"2858newUNSN","price":799.0,"currency_code":"USD","in_stock":true}]},{"product_id":"unison-research-unico-dm-v2-power-amplifier","title":"Unison Research Unico DM v2 Power Amplifier","description":"\u003ch2 dir=\"ltr\"\u003e\u003cspan\u003eUnison Research Unico DM v2 Stereo Power Amplifier Key Features:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eA.S.H.A.
