{"product_id":"gold-note-pa-1175-mki-power-amplifier","title":"Gold Note PA-1175 MkI Power Amplifier","description":"The Gold Note PA-1175 MkI solid-state power amplifier delivers 175 watts per channel into 8 ohms and bridges to 350 watts in mono mode. Built to anchor ambitious audio setups, this Italian design balances authoritative muscle with delicate acoustic nuance. The circuit incorporates four matched transistor pairs per channel governed by a proprietary Optical BIAS system, which decouples bias regulation optically from the audio signal path. A front-panel switch alters the damping factor between 250 for controlling demanding woofers and 25 for generating a tube-like warmth with high-efficiency speakers. Encased in a rigid steel chassis with thick aluminum panels, a custom 630VA toroidal transformer with a vibration-canceling spiral core supplies stable, uninterrupted current.\n\nReviews praise this amplifier for its transparent presentation, expressive midrange fluidity, and muscular low-end grip. Critics highlight the selectable damping factor as a standout feature, noting how easily it resolves speaker matching while maintaining an expansive soundstage. Hi-fi publications commend its innovative optical bias architecture, frequently citing its ability to render subtle instrumental textures alongside effortless dynamic swings.\n\nIntegrating this amplifier into your system brings genuine ease and tonal richness to every recording. Its balanced power delivery allows loudspeakers to operate at their absolute best, uncovering lifelike depth across your entire music collection.","brand":"Gold Note","offers":[{"title":"Default Title","offer_id":67854879818009,"sku":"101232","price":2129.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/101232-3.jpg?v=1794251889","url":"https:\/\/tmraudio.com\/products\/gold-note-pa-1175-mki-power-amplifier","provider":"The Music Room","version":"1.0","type":"link"}
