Featuring a purpose-designed Class A\/B circuit with 60W (8Ω) power output, there’s little this amplifier cannot work with.\u003c\/p\u003e\n\u003cul class=\"align-left product-features-list\" id=\"productFeatureListFirst6\"\u003e\n\u003cli\u003eHDMI Licensed\u003c\/li\u003e\n\u003cli\u003eHDMI-ARC connectivity for seamless connection with a TV\u003c\/li\u003e\n\u003cli\u003eRemote control included\u003c\/li\u003e\n\u003cli\u003eClass AB amplifier design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eIn a nutshell\u003c\/h2\u003e\n\u003cp\u003eDesigned for today’s diverse listening needs, the B1xi features an array of input options. From the low-noise, high-gain MM phono stage, through multiple line-level inputs for other traditional sources, and onto the built-in DAC, HDMI ARC input and Bluetooth receiver for wireless streaming – each input is optimised for the best possible performance. There’s also an array of broader connectivity on offer, including the RCA variable pre-output for subwoofers or a dedicated power amplifier, a 5V USB-C power output for running an external streamer, a front-mounted mini-jack line input, and a headphone output for private listening sessions.\u003c\/p\u003e\n\u003ch2\u003eNo WiFi by design\u003c\/h2\u003e\n\u003cp\u003eThe only feature you might consider missing from the B1xi is Wi-Fi streaming – but that decision is deliberate. Where others might produce “all-in-one” streaming amplifiers, they often have to compromise on quality – or they become very expensive. Built-in streaming can also limit the amplifier’s lifespan, as when the playback technology is superseded, the hardware can often become unusable or less functional. At Musical Fidelity, everything is produced with a focus on good hardware, robust design, and a desirable sound quality that means your investment can last for decades. The B1xi can play nicely with any external streamer, and by keeping the source device separate you can guarantee the amplifier can play at the heart of your system for years to come.\u003c\/p\u003e\n\u003ch2\u003ePure Class A\/B Excellence with True High-End Audiophile Design\u003c\/h2\u003e\n\u003cp\u003eThe B1xi benefits from a premium amplifier design, using transistor amps in Class A\/B to deliver a highly engaging, tube-like sound. Delivering 60 watts into 8 ohms (100W, 4Ω \/ 140W, 2Ω), it doesn’t struggle to drive a wide variety of speakers. There’s a good degree of headroom on offer for proper peak power delivery and a wide dynamic range, meaning your listening experience is never strained.\u003c\/p\u003e\n\u003cp\u003eThe pre-amplifier section of the B1xi features its own dedicated linear power supply, ensuring ultra-low noise and excellent channel separation. This design effectively treats the integrated amplifier as electrically separate pre- and power-amp stages. Volume control is handled via a motor-driven analogue potentiometer for the purest signal control.\u003c\/p\u003e\n\u003ch2\u003ePremium Throughout\u003c\/h2\u003e\n\u003cp\u003eThe internal layout of the B1xi is optimised for perfect sound – despite the many features that are included. Once you take the lid off, you can see that the potentially interference-inducing digital boards are physically separated into their own PCBs with their own linear power supply. Other signs of quality are found in the amplifier’s industrial design. The robust metal controls on the extruded aluminium front panel merge stylishly with the metal chassis, giving a sense of control and reliability to every aspect of the design.\u003c\/p\u003e\n\u003ch2\u003eFocus on the Sound\u003c\/h2\u003e\n\u003cp\u003eThe B1xi is a true hi-fi amplifier, designed by music lovers. By focusing on good design principles and high-end sound performance, and equipping the design with good connectivity options, this is the ideal system hub for anyone looking for great sound at an affordable price.\u003c\/p\u003e\n\u003cul class=\"product-specifications-list\" id=\"productSpecificationList\"\u003e\n\u003cli\u003e\n\u003cdiv\u003eAmplifier Type: Integrated Amplifier\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eAmplifier Class: A-B\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003ePower Output (4Ω): 100 W\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003ePower Output (8Ω): 60 W\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eAmplifier Voltage Output: 21 V RMS, 30 V Peak\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eAmplifier Current Output: 8 Amps Peak\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eOutput Devices: 1 Pair Per Channel\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eFrequency Response: 20Hz - 20kHz\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003ePhono Input Sensitivity (MM): 5 mV\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eDamping Factor: 30\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eSignal To Noise Ratio: 100 dB\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eSignal To Noise Ratio (MM Input): \u0026gt;70 dB\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003ePhono Input: MM Input \u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003ePhono Stage Impedance (MM): 47 kΩ\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003ePhono Input Gain (MM): 42dB\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eRCA Input(s): 3\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eBluetooth Version: 5.1 \u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eHDMI Input(s): ARC Input\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eOptical Input(s): 1 (24-bit, 192kHz)\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eCoaxial Input(s): 1 (24-bit, 192kHz)\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eDAC Chip: ESS9018\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eFixed Analogue Output(s): 1 x RCA Pair\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eEnclosure Material: Metal\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eMaximum Power Consumption: 280 W\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eDimensions (W x H x D): 430 x 90 x 324 mm\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv\u003eWeight: 7.2 kg\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Musical Fidelity","offers":[{"title":"Default Title","offer_id":57920777027916,"sku":"MFIDELITY-B1xi","price":582.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/MFIB1XI-ProductMain_StockPhoto_Front.jpg?v=1782729555","url":"https:\/\/www.stoneaudio.co.uk\/products\/musical-fidelity-b1xi","provider":"Stone Audio","version":"1.0","type":"link"}
