{"product_id":"first-watt-sit-4-power-amplifier-unused","title":"First Watt SIT-4 Power Amplifier (Unused)","description":"The First Watt SIT-4 is a single-ended Class A solid-state power amplifier delivering 10 watts per channel into 8 ohms with a maximum output current of 2.5 amperes. Serving as an ultra-purist centerpiece for high-sensitivity systems, this component distills Nelson Pass's design philosophy into a simple signal path. It utilizes a Tokin THF51s Static Induction Transistor per channel operating without global feedback to mimic the curve of a triode tube. Driven by a Toshiba JFET input stage with a mu-follower current source, the heavy chassis features passive heatsinks and premium rear speaker terminals.\n\nAudio reviewers acclaim this amplifier for delivering an extraordinarily three-dimensional soundstage, rich tonal saturation, and triode-like intimacy without vacuum tubes. Outlets like HiFi Knights awarded it top honors, praising its ability to extract micro-detail, punchy bass, and realistic spatial depth from efficient speakers. Critics emphasize that while its modest power requires thoughtful speaker matching, its liquid presentation and total lack of grain easily outperform standard high-power designs.\n\nInvesting in this amplifier means prioritizing musical expressiveness and tonal realism over raw volume. Its unique transistor topology eliminates electronic harshness, allowing delicate vocal nuances and natural acoustic textures to shine. For the enthusiast with sensitive loudspeakers, it provides an engaging listening experience that connects you directly to the heart of the performance.","brand":"First Watt","offers":[{"title":"Default Title","offer_id":67667866943769,"sku":"99520","price":4549.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/99520-6.jpg?v=1791310975","url":"https:\/\/tmraudio.com\/products\/first-watt-sit-4-power-amplifier-unused","provider":"The Music Room","version":"1.0","type":"link"}
