With its dual-mono topology and zero global feedback architecture, it exemplifies the essential principles of high-fidelity audio reproduction.\u003c\/strong\u003e\u003cbr\u003e\u003chr\u003e\u003cbr\u003eAt the heart of the Unico PRE v2 lies a carefully crafted hybrid architecture that fuses the acoustic virtues of vacuum tubes with the precision of solid-state electronics. Utilizing a pair of ECC83 \/ 12AX7 Gold Lion valves in the first amplification stage, this preamplifier establishes a sonic character characterized by signal purity, exceptionally low distortion, and quiet operation, effectively minimizing noise floor and maximizing dynamic range. The subsequent solid-state stages complement the valve section, enabling robust signal processing even under adverse conditions. Additionally, the balanced design extends to the integrated DAC section with a Sabre ES9018K2M converter, optimizing phase coherence and harmonic balance across both analog and digital inputs. By employing high-precision resistors for volume control, Unico PRE v2 ensures impeccable channel matching and signal integrity, making it an exemplary choice for discerning listeners seeking authentic audio fidelity.\u003cbr\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eZero Global Feedback Design:\u003c\/strong\u003e This approach minimizes inter-modulation distortion, preserving the integrity of audio signals across all frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Mono Topology:\u003c\/strong\u003e By using separate circuits for left and right channels, the configuration enhances stereo imaging and minimizes crosstalk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Quality Volume Control:\u003c\/strong\u003e The precision resistors used allow for fine adjustments in volume levels, which maintains consistent channel balance and audio fidelity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated DAC with Sabre ES9018K2M:\u003c\/strong\u003e Leveraging advanced digital-to-analog conversion, this DAC supports high-resolution audio with minimal latency and distortion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Load and Gain Settings in Phono Stage:\u003c\/strong\u003e Customizable configurations ensure optimal performance with different MM and MC cartridges, maintaining the quality of analog playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtensive Connectivity:\u003c\/strong\u003e With various input types including RCA, XLR, USB, and Toslink, the Unico PRE v2 can seamlessly integrate with a wide range of audio systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eType: Fully balanced hybrid preamplifier\u003c\/li\u003e\n\u003cli\u003eValves: 2 × ECC83 \/ 12AX7 Gold Lion\u003c\/li\u003e\n\u003cli\u003eOperating Mode: Class A\u003c\/li\u003e\n\u003cli\u003eOutput Stage: Solid State\u003c\/li\u003e\n\u003cli\u003eVolume Control: Infrared\u003c\/li\u003e\n\u003cli\u003eAnalogue Inputs: 3 × Line RCA, 3 × Line XLR, 1 × Phono MM \/ MC, 1 × Line In\u003c\/li\u003e\n\u003cli\u003eDigital Inputs: 1 × USB, 2 × Toslink, 2 × S\/PDIF\u003c\/li\u003e\n\u003cli\u003eMaximum Input Voltage: 2.58 Vrms (RCA), 5 Vrms (XLR)\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 20 kΩ (RCA), 57 kΩ (XLR)\u003c\/li\u003e\n\u003cli\u003eGain: 20 dB (RCA), 15 dB (XLR)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Unison Research","offers":[{"title":"Midnight Black","offer_id":43088229957745,"sku":"URUNICOPREV2MB","price":4499.0,"currency_code":"USD","in_stock":true},{"title":"Velvet Gold (Special Order)","offer_id":43088229990513,"sku":"URUNICODMV2VG","price":4499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/0571\/7617\/files\/unico-pre-10.jpg?v=1774188109","url":"https:\/\/shopodsy.com\/products\/unison-research-unico-pre-v2","provider":"ODSY","version":"1.0","type":"link"}
