Inputs: 3 RCA, 2 balanced, 1 bypass; outputs: 2 RCA, 2 balanced. The VAC Master Stereo Tube Preamplifier uses trickle-down engineering from the flagship Statement series. Hand-wired Class A1 circuits sit on decoupled mass-loading plates to eliminate microphony. It features premium transformers, \"naked\" Z-foil resistors, and an optional phono stage adding six 12AX7 tubes and an isolated power transformer.\n\nReviews praise the Master for a revelatory performance combining the speed, grip, and bass of solid-state with the fluid, holographic warmth of tubes. Critics highlight its incredible scale, fast transients, and deep resolution of micro-details without fatigue. Reviewers emphasize that it maintains immense control over complex musical climaxes while projecting a spacious soundstage, calling both the line stage and the optional phono section reference-level achievements.\n\nThis preamplifier acts as the ultimate system anchor, transforming recordings into a lifelike musical event. Stripping away the electronic veil allows listeners to follow individual textures with absolute clarity. Finding a component offering this effortless bloom and freedom from source interaction is rare. To elevate playback to an entirely new playing field, integrating this line stage is the definitive step toward sonic perfection.","brand":"The Music Room","offers":[{"title":"Default Title","offer_id":53236106166553,"sku":"100536","price":18999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/97378-9_d92810ce-ab5a-4826-85cd-cc1294482c4d.jpg?v=1790120656","url":"https:\/\/tmraudio.com\/products\/vac-master-dual-chassis-tube-preamplifier","provider":"The Music Room","version":"1.0","type":"link"}
