A fully discrete Class A\/B power amp delivers 60W per channel into 8 ohms, 100W into 4 ohms, and 140W peaks into 2 ohms, driving power-hungry and difficult speakers with ease. It includes a comprehensive input selection: MM phono stage, coaxial and optical digital inputs, HDMI ARC, Bluetooth 5.1, and three RCA line inputs, along with a variable RCA pre-out for subwoofer connection or bi-amping and a 5V USB-C output for powering an external streamer. The B1xi is built with an all-metal chassis, solid metal controls, and a front panel milled from extruded aluminium. As an authorized Musical Fidelity dealer in Toronto, Canada, Vinyl Sound can help you match this amplifier to your speakers and sources.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0116\/1773\/0617\/files\/B1xi-detail-3-528x352.jpg?v=1784087538\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFully discrete Class A\/B power amp: 60W\/8Ω, 100W\/4Ω, 140W peak\/2Ω\u003c\/li\u003e\n\u003cli\u003eDedicated linear power supply for the preamp section, separate from the power amp\u003c\/li\u003e\n\u003cli\u003eMotor-driven analogue volume potentiometer, preserving signal purity\u003c\/li\u003e\n\u003cli\u003eLow-noise, high-gain MM phono stage\u003c\/li\u003e\n\u003cli\u003ePhysically separated digital and ARC boards, each with their own linear power supply\u003c\/li\u003e\n\u003cli\u003eESS9018 DAC, accepting up to 24-bit\/192kHz via coaxial and optical inputs\u003c\/li\u003e\n\u003cli\u003eBluetooth 5.1 input\u003c\/li\u003e\n\u003cli\u003eHDMI ARC input for home theatre integration\u003c\/li\u003e\n\u003cli\u003eVariable RCA pre-out for bi-amping or active subwoofer connection\u003c\/li\u003e\n\u003cli\u003e5V USB-C power output for an external streamer\u003c\/li\u003e\n\u003cli\u003eGenerously rated toroidal transformer with independent power supplies for preamp, power amp, and digital sections\u003c\/li\u003e\n\u003cli\u003eNo built-in WiFi, display, or app — Musical Fidelity states this keeps fast-moving streaming tech from affecting the amplifier's long-term reliability and sound quality focus\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0116\/1773\/0617\/files\/B1xi-detail-2_2-528x352.png?v=1784087538\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eClass A\/B Power Design\u003c\/h2\u003e\n\u003cp\u003eThe B1xi's fully discrete Class A\/B power amp is paired with its own dedicated power supply and a generously proportioned toroidal transformer, providing power reserves for peak delivery and a wide dynamic range.
