It transforms electrical signals into immersive audio by precisely managing the power output and signal processing.\u003c\/strong\u003e\u003cbr\u003e\u003chr\u003e\u003cbr\u003eThe Unison Research Triode 25 Black Edition utilizes a push-pull, ultralinear configuration to optimize power efficiency while maintaining low distortion levels. By allowing output valves to operate in either triode or pentode mode, it balances warm tonal quality with substantial power output—30 W in triode mode and 50 W in pentode mode. The amplifier features a revised signal path that enhances audio fidelity through component quality and design, while its adjustable feedback control allows users to tailor the response characteristics of the amplifier for various listening environments. The incorporation of digital inputs via the DAC3 adds versatility without sacrificing the integrity of the analog signal, which is protected by high-quality coaxial cabling. The design also emphasizes meticulous ground paths and channel separation, ensuring minimal interference and optimal stereo imaging.\u003cbr\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriode and Pentode Modes:\u003c\/strong\u003e Enables user-selectable power output—30 W for smooth, warm sounds in triode mode or 50 W for dynamic headroom in pentode mode.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Feedback:\u003c\/strong\u003e Allows fine-tuning of the amplifier’s response characteristics, effectively managing distortion and enhancing clarity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubwoofer Output:\u003c\/strong\u003e Unfiltered output maintains the amplifier’s sonic signature while connecting to an active subwoofer for deeper bass performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicro Relay Input Selection:\u003c\/strong\u003e High-precision micro relays enhance input switching reliability and preserve signal integrity during source changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Inputs:\u003c\/strong\u003e Includes 3 analog inputs and advanced digital connections (USB, SPDIF, Toslink) through the DAC3, enabling high-resolution audio streaming without loss of quality.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOutput power: 50 W (pentode mode), 30 W (triode mode)\u003c\/li\u003e\n\u003cli\u003eBandwidth (-1 dB): 10 Hz - 50 kHz\u003c\/li\u003e\n\u003cli\u003eSignal valves: 2x ECC83 Gold Lion, 1x ECC82 Gold Lion\u003c\/li\u003e\n\u003cli\u003eOutput power valves: 4x KT77 Gold Lion in push-pull configuration\u003c\/li\u003e\n\u003cli\u003ePolarization: Class AB\u003c\/li\u003e\n\u003cli\u003eInputs: 3x line RCA, 1x USB, 1x SPDIF, 1x Toslink\u003c\/li\u003e\n\u003cli\u003eOutputs: 1x subwoofer RCA (stereo), 1x line out\u003c\/li\u003e\n\u003cli\u003eFeedback: 10 dB to 12 dB selectable\u003c\/li\u003e\n\u003cli\u003eProduct dimensions: 300 x 200 x 450 mm\u003c\/li\u003e\n\u003cli\u003eNet weight: 20.00 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Unison Research","offers":[{"title":"Black","offer_id":43088230056049,"sku":"URT25BLACKEDITION","price":4499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/0571\/7617\/files\/RED04206.jpg?v=1774188112","url":"https:\/\/shopodsy.com\/products\/unison-research-triode-25-black-edition","provider":"ODSY","version":"1.0","type":"link"}
