It's been designed to be faithful to the Unison Research tradition, by making it an integrated amplifier design that sounds great and pays attention to important audio engineering principles that reduce performance-affecting interference.\u003cbr\u003e\u003cbr\u003e\n\nBecause of the overwhelming success of the design, the Simply Italy shares many of the design features of the Simply Two. Both are ultra-linear, single-ended Class A designs that produce 12W per channel, and both use EL34 valves in the output stage and ECC82 valves in the pre-amp and driver stages to achieve Unison Research's trademark imaging, clarity and musical precision. But the Simply Italy offers a wide range of new features that were designed and developed more recently.\u003cbr\u003e\u003cbr\u003e\n\nFirst, the output impedance has been adjusted from 8Ω to 6Ω, making the amplifier compatible with a greater variety of loudspeakers. Also, since a true dual-mono configuration would be impractical in such a compact amplifier, Unison Research designed a new “Quasi-Dual-Mono” power supply. In this configuration, the power transformer and first filter stage of the power supply are doubled, separating all pre-amp stages to allow for lower cross-talk and low distortion.\u003cbr\u003e\u003cbr\u003e\n\nThanks to Unison Research's ability to design specialised transformers in house, the Simply Italy is able to have an output stage consisting of one EL34 in a single-ended ultra-linear configuration. This mode of operation for the output transformers allows the pentode EL34s to operate almost as if they were triodes. Furthermore, an additional toggle switch allows for an adjustment of negative feedback in the circuit. This means the sound character of the amplifier can be adjusted to suit specific types of music or listening environments.\u003cbr\u003e\u003cbr\u003e\n\nThe appearance of the Simply Italy has undergone radical changes, when compared to the Simply Two. The front panel is a locally-sourced wood that's accented by contrasting wood inserts around the controls, that also acts as an anti-resonant support for the metal chassis. Then two stainless-steel bands beneath the valves add a touch of refinement, while additionally aiding performance by thermally isolating the valves from the electronic circuitry and output transformers. Finally, the control knobs are made from non-magnetic stainless-steel with a sufficient diameter and weight to provide a smooth 'flywheel' effect with excellent feel and rotational precision.\u003cbr\u003e\u003cbr\u003e\n\nThe Simply Italy is supplied with an infra-red remote handset which allows for convenient control over input switching and the premium motorised volume pot from ALPS. The back panel is finished with four large gold-plated terminal connectors that allow any type of loudspeaker cable to be connected easily, alongside clearly marked RCA inputs for multiple audio sources.\u003cbr\u003e\u003cbr\u003e\n\nDue to the nature of the valve electronics in the Simply Italy, we recommend only pairing it with speakers that have a minimum impedance (not nominal impedance) of 4Ω and are rated higher than 89dB sensitivity to avoid damage to the amplifier and overloading the component electronics. Check also that your speakers are capable of being driven by a 12W output amplifier.\u003cbr\u003e\u003cbr\u003e\n\nKey Features:\u003cbr\u003e\n•Ultra-linear, single-ended Class A integrated amplifier\u003cbr\u003e\n•Based on the iconic Simply Two design\u003cbr\u003e\n•Combination of EL34 and ECC82 valves used\u003cbr\u003e\n•6Ω output impedance for easier speaker matching\u003cbr\u003e\n•Specially designed power supply to suit compact size\u003cbr\u003e\n•Switchable toggle for changing effects of negative feedback\u003cbr\u003e\n•Wood panel front plate adds extra damping to metal casework\u003cbr\u003e\n•Clearly-labelled inputs and outputs\u003cbr\u003e\n•IR remote allows for convenient operation\u003cbr\u003e\n•RK27 Series motorised potentiometer from ALPS used for the volume pot\u003cbr\u003e\n•RC2 remote with black wood finish included\u003cbr\u003e\n•Premium Cherry Wood front panel*\u003cbr\u003ev\n\nTechnical Data:\u003cbr\u003e\n\nType: Stereo Integrated Valve Amplifier\u003cbr\u003e \nOutput Stage: Single-Ended, Ultra-Linear, Class A \u003cbr\u003e\nOutput Power: 12W per-channel (approx.) \u003cbr\u003e\nOutput Impedance: 6Ω \u003cbr\u003e\nInput Impedance: 47kΩ \/ 50pF \u003cbr\u003e\nNegative Feedback: Switchable, 5dB or 1.8dB \u003cbr\u003e\nValves:\n\n 2 x ECC82 (12AU7)\n 2 x EL34 (6CA7) \u003cbr\u003e\nPower Consumption: 85W \u003cbr\u003e\nFuses: T1.6A from 220V-240V \u003cbr\u003e\nDimensions (W x D x H): 26 x 35 x 19cm \u003cbr\u003e\nNet Weight: 15kg ","brand":"Unison Research","offers":[{"title":"Black","offer_id":57413359829324,"sku":"URESEARCH-SIMPLYITALY-B","price":1666.67,"currency_code":"GBP","in_stock":true},{"title":"Cherry","offer_id":57422996078924,"sku":"UNISONRESEARCHSIMPLYITALY-C","price":1666.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Unison-Research-Simply-Italy.jpg?v=1777542709"},{"product_id":"unison-research-preludio-integrated-amplifier","title":"Unison Research Preludio Integrated Amplifier","description":"Preludio\u003cbr\u003e\u003cbr\u003e\n\nPreludio is an integrated tube amplifier that maintains the distinctive technical elements, sound characteristics and stunning looks that Unison Research is known for.

It's been developed over an extended period to ensure it is a worthy successor to the Triode 20's name.\u003cbr\u003e\u003cbr\u003e\n\nLike its predecessor, the Triode 25 is a push-pull amplifier that utilizes EL34 tubes in the output stage. The push-pull circuit includes a final stage with two power tubes intended for the amplification of the audio signal, and is then followed by a symmetrical output transformer stage that reconstructs the signal into a high-quality linear wave. \u003cbr\u003e\u003cbr\u003e\n\nUsing a push-pull structure in this amplifier design allows for numerous benefits, including higher-output power compared to single-ended designs, improved efficiency and no static polarization of the output transformer for greater performance in the output section. However, for this to work well it is essential that all the individual amplification stages are carefully designed and constructed to prevent the formation of dangerous and compromising odd-order harmonic distortion. This is true for the two semi-output amplifiers, and even more important in the output transformer.\u003cbr\u003e\u003cbr\u003e\n\nThe Triode 25 can operate in two modes: triode and pentode.

By making this an integrated design Unison Research have stayed true to their traditions, supporting the philosophy that integrated amplifiers can achieve a better sound by taking away the need for external cables, as cable impedances can negatively effect the timbre and dynamics of a hi-fi system's delivery.\u003cbr\u003e\u003cbr\u003e\n\nThe Sinfonia is a dual-mono design, which effectively eliminates the possibility of cross-channel electrical interference. Each amplification stage inside the Sinfonia is pure Class A and operates exclusively with valves. The amplifier is able to deliver a very capable 27-30W (max.) output power, per channel.\u003cbr\u003e\u003cbr\u003e\n\nThe Sinfonia, like the Performance, is accented by two large heat-sink \"wings\" mounted on the sides. These are required by the high voltage stabilized power supply circuits, which are protected by a wide stainless steel cover. The top-plate is non-magnetic stainless steel and has low thermal conductivity, so it prevents the heat generated by the four KT88 from reaching the circuits located inside. This improves the stability of the amplifier, which in turn enhances the sound quality and the overall reliability of the system.\u003cbr\u003e\u003cbr\u003e\n\nThanks to Unison Research's extensive knowledge of output transformer production, the Sinfonia has been designed with a power stage that is made up of two KT88 valves per-channel in single-ended parallel ultra-linear configuration, in which the KT88 (beam power tetrodes) operate, with good approximation, like an ideal triode. This configuration provides very good results in terms of sound quality, however the natural drawbacks of valves (namely the non-uniform decline in performance over time due to drift) need to be addressed. So, after much testing, Unison Research developed an an original circuit design which, through the control of the KT88 bias, ensures a real-time compensation of the parameters affected by drift. This solution guarantees the best sound quality even after many years, and also contributes to a slight reduction in the time it normally takes for the tubes to warm up after switching on and reach the optimal temperature.\u003cbr\u003e\u003cbr\u003e\n\nThe pre-amplification and the power stage drive are based on the double triodes ECC83 and ECC82. These valves guarantee excellent linearity and offer a nearly complete absence of odd-order harmonic distortion components. Both the stages are made up of triodes in parallel and are biased by automatic bias circuits. In this way the output impedance of the two circuits can be slightly reduced, which in turn improves the linearity of the stages. The signal-to-noise ratio and the total harmonic distortion improve significantly in this design as well. The direct current on the preamplifier valve filaments is supplied by an interesting circuit configuration: it works by directing the power stage valves cathode current through a parallel regulator which operates like a zener diode to the filament’s terminal.\u003cbr\u003e\u003cbr\u003e\n\nWith audio amplifiers, the anodic voltage should ideally be supplied by a battery, but this is obviously not possible for a number of practical reasons. So, to compensate, the Sinfonia employs a special anodic power supply circuit that features an output capacitance that is much higher than usual, emulating the performance of a battery supply.\u003cbr\u003e\u003cbr\u003e\n\nThe appearance of Sinfonia is both striking and functional. The control knobs are machined from solid, non-magnetic stainless steel and are weighted and balanced to provide a smooth, precise performance when used. The wooden parts, aside from their obvious visual beauty, effectively dampen out induced resonance in the metal chassis. Thanks to this structural damping, the valves themselves, which like all vacuum tube devices are susceptible to microphony, are much less liable to generate unwanted resonance-related effects. For the best reliability and long term musical quality, all the components used in the Sinfonia have been chosen with care from the non-inductive resistors and the filter capacitors, to the pure ceramic valve bases and the vetronite printed boards. The dimensions, distribution and lay out of the PCBs have been accurately studied and optimized to limit electrical disturbances and prevent components from overheating.\u003cbr\u003e\u003cbr\u003e\n\nThe supplied infra-red remote handset allows for convenient control over input switching and the premium motorised volume pot from ALPS. The back panel is finished with six gold-plated speaker terminal connectors that allow the connection of 4Ω and 8Ω loudspeakers, alongside clearly marked gold-plated RCA inputs for multiple audio sources. Next to the \"Tape Out\" connector is an additional low-impedance output terminal for connecting an active subwoofer; this terminal is linked to the pre-amplifier stage directly for reliable sub-performance. The source inputs have a buffer-stage to eliminate any negative effects connecting a subwoofer could have on the performance of the amplifier. The back-panel also has a power cable connector for upgrading the basic power supply included with the Simply Phono phono stage.\u003cbr\u003e\u003cbr\u003e\n\n\nKey Features:\u003cbr\u003e\n•Dual mono Stereo Integrated Valve Amplifier\u003cbr\u003e\n•Single-ended Parallel Class A output stage\u003cbr\u003e\n•KT88 valves used in sophisticated output stage design\u003cbr\u003e\n•Based on the superior Performance amplifier\u003cbr\u003e\n•27-30W output\u003cbr\u003e\n•Subwoofer output\u003cbr\u003e\n•4Ω and 8Ω loudspeaker terminals\u003cbr\u003e\n•Simply Phono power supply upgrade built-in\u003cbr\u003e\n•RC2 remote included\u003cbr\u003e\n•High-quality Cherry Wood finish*\u003cbr\u003e\u003cbr\u003e\n\nTechnical Data:\u003cbr\u003e\n\n\nType: Dual-Mono Stereo Integrated Valve Amplifier \u003cbr\u003e\nOutput Stage: Single-Ended Parallel Ultra-Linear Class A \u003cbr\u003e\nOutput Power: 25W\u003cbr\u003e \nInputs:\n\n 4 x Line\n 1 x Tape \u003cbr\u003e\nInput Impedance: 47kΩ \u003cbr\u003e\nOutputs:\n\n\n 1 x Tape\n 1 x Subwoofer\n Loudspeakers (bi-wiring)\u003cbr\u003e\n \nOutput Impedance: 4 - 8Ω \u003cbr\u003e\nFeedback Factor: 14dB \u003cbr\u003e\nFrequency Response: 20 - 30,000Hz \u003cbr\u003e\nValves:\n\n\n 4 x 6550 \/ KT88\n 2 x ECC82\n 2 x ECC83 \u003cbr\u003e\nRemote Control: IR control of inputs and volume \u003cbr\u003e\nPower Consumption: 500W (max.) \u003cbr\u003e\nDimensions (W x D x H): 44 x 42 x 21cm \u003cbr\u003e\nNet Weight: 55lbs. \u003cbr\u003e\u003cbr\u003e\n\n*Sinfonia with Mahogany finish is available to Special Order.\n","brand":"Unison Research","offers":[{"title":"Default Title","offer_id":57413359927628,"sku":"UNISONRESEARCHSINFONIA","price":3541.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Unison-Research-Sinfonia.jpg?v=1777542723"},{"product_id":"unison-research-performance-integrated-amplifier","title":"Unison Research Performance Integrated Amplifier","description":"Performance\u003cbr\u003e\u003cbr\u003e\n\nOver the decades that Unison Research have been designing and building audio products, they have always listened to the concerns and comments of their valued customers; and over time they have realised that those customers' needs have changed. As a result of this ongoing willingness to listen, they are constantly developing new and existing products to suit the ever-changing needs of their customers. Enter the latest version of the long-standing Performance integrated amplifier.\u003cbr\u003e\u003cbr\u003e\n\nThe Performance is a single-ended Class A integrated amplifier with a parallel internal layout for ultimate sound-staging and an authentic valve experience. This latest version offers increased power, when compared to its predecessor, while staying true to the important characteristics of timeless aesthetics and pure musical pleasure.\u003cbr\u003e\u003cbr\u003e\n\nThe few visual changes are due to functional necessity, such as the insertion of large thermic radiators on either side, and the two stainless steel screens that act as a cover. This cover is amegnetic, with low heat conduction and it's used to prevent the heat generated by the six KT-88s from reaching the circuitry below, which benefits the sound quality as well as overall reliability.\u003cbr\u003e\u003cbr\u003e\n\nAs with all high quality integrated amplifiers, the Performance is laid out in dual-mono configuration.

With these valves it is possible to obtain excellent linearity and a virtual absence of odd-order harmonic distorsion.

By making this a hybrid design, where a power amplifier is combined with an ECC83 triode, you get the best of both worlds with the Unico Primo.

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.

The SH is a single-ended, two-stage full-valve headphone amplifier designed to accommodate traditional analogue and modern computer-based audio sources.\u003cbr\u003e\u003cbr\u003e\n\nThe SH began with the same basic remit as the coveted Simply Italy integrated amplifier; to produce a world-class sound from a specialised device using the best technology available. The result was a fairly simple, linear circuit that produces an output voltage which is more than capable of driving a wide range of headphones, while keeping distortion low throughout the frequency range. This allows the SH to deliver a consistent, coherent sound character when in use.\u003cbr\u003e\u003cbr\u003e\n\nThe input stage uses ECC83 valves, while the output stage uses one EL84 valve (both operating in triode mode). The benefits to using this specific combination of valves are in the reduced power requirements for how the valves are usually employed, resulting in extended life, and the EL84’s ability to drive an output transformer with optimal electrical and sound qualities. \u003cbr\u003e\u003cbr\u003e\n\nThe SH comes equipped with two headphone outputs, connected in parallel for easy switching between headphones, or to accommodate multiple listeners. There is also a “Sensitivity” switch, to ensure the widest possible range of headphones can be comfortably driven by this amplifier. When set to “High Sensitivity”, the output voltage from the amplifier is reduced, and at “Low Sensitivity” it is at its maximum. The added advantage of this switch is for maintaining optimal sound quality while listening to music at lower volumes.\u003cbr\u003e\u003cbr\u003e\n\nIn addition to a standard un-balanced RCA input for connecting any traditional analogue source, the SH is also equipped with a class-leading USB DAC. The asynchronous USB 2.0 technology is the same as found on the recent Triode 25 amplifier, and supports audio formats up to 384kHz PCM and DSD 128. The patented jitter-elimination circuit ensures a great sonic performance, assisted by the galvanic isolation employed between the power areas of the USB interface and the conversion IC.

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.\u003cbr\u003e\u003cbr\u003e\n\nThe 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.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:-\u003cbr\u003e\u003cbr\u003e\n\nOutput Power: 100W Per-Channel, RMS (8Ω), 180W Per-Channel, RMS (4Ω), 290W Per-Channel, RMS (2Ω)\u003cbr\u003e \nFilter Capacitance: 80,000µF \u003cbr\u003e\nOutput Stage: Dynamic Class A Power BJT, Double Complementary Pair “Super-Symmetric” Configuration \u003cbr\u003e\nBiasing: Dynamic Class A \u003cbr\u003e\nValves: 2 x ECC83 (12AX7)\u003cbr\u003e\u003cbr\u003e \nInputs:\u003cbr\u003e \n2 x Analogue Line (RCA)\u003cbr\u003e\n1 x Analogue Phono (RCA) – Set to MM\u003cbr\u003e\n1 x Digital (USB)\u003cbr\u003e\n1 x Tape (RCA)\u003cbr\u003e\u003cbr\u003e \n\nAnalogue Line Outputs:\u003cbr\u003e \n1 x Tape (RCA) – Fixed\u003cbr\u003e\n1 x Stereo Subwoofer (RCA) – Variable\u003cbr\u003e\n1 x DAC (RCA) - Fixed \u003cbr\u003e\u003cbr\u003e\n\nSpeaker Output Connectors: 4 + 4 (Bi-Wirable)\u003cbr\u003e \nDimensions (W x D x H): 43.5 x 43 x 13cm","brand":"Unison Research","offers":[{"title":"Unison Research Unico Due - Integrated Amplifier - Silver","offer_id":57415253623116,"sku":"URESEARCHUNICODUE-S","price":2083.33,"currency_code":"GBP","in_stock":true},{"title":"Unison Research Unico Due - Integrated Amplifier - Black","offer_id":57423916859724,"sku":"URESEARCHUNICODUE-B","price":2083.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Unison-Research-Unico-Due-Silver.jpg?v=1777555187"},{"product_id":"unison-research-sinfonia-anniversary-integrated-amplifier","title":"Unison Research Sinfonia Anniversary Integrated Amplifier","description":"Sinfonia Anniversary - SPECIAL ORDER ITEM \u003cbr\u003e\u003cbr\u003e\n\nKey Features:\u003cbr\u003e\n•Special edition integrated amplifier\u003cbr\u003e\n•Built to celebrate 25th anniversary of Unison Research\u003cbr\u003e\n•Upgraded Gold Lion valves\u003cbr\u003e\n•Bronze top-plate\u003cbr\u003e\u003cbr\u003e\n\nValve Series\u003cbr\u003e\u003cbr\u003e\n\nThe Sinfonia Anniversary is a special edition version of the Sinfonia integrated amplifier.
