This separation ensures ultra-low noise and excellent channel separation, rivaling high-end pre\/power separates. Volume control is handled via a motor-driven analogue potentiometer, preserving signal purity—unlike many modern digital volume controls that compromise fidelity due to a loss in signal resolution. Vinyl lovers will appreciate the B1xi’s exceptionally low-noise, high-gain phono stage. Carefully tuned for musicality and detail, it brings out the best in your MM cartridges without adding coloration or distortion.\u003c\/p\u003e\n\u003ch3\u003eSeparate digital boards\u003c\/h3\u003e\n\u003cp\u003eDigital and analogue hardware needs to be carefully separated from each other. Even the smallest amount of RF interference is known to cause trouble for analogue amplifier stages. Therefore, the digital and ARC boards are physically separated on their own PCBs and have their own linear power supply.\u003cbr\u003e\u003cbr\u003eDrawing from our decade long experience in designing DACs (recently with our ground-breaking Nu-Vista DAC and M8x DAC), the B1xi uses a carefully trimmed DAC design using the superb ESS9018 chip. The digital coaxial and optical inputs accept high-resolution sample rates up to 24bit and 192kHz and the HDMI ARC input allows your home theatre to be brought to life and properly invigorated by the powerful B1xi analogue amp stages.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ccenter\u003e\u003cimg src=\"https:\/\/www.musicalfidelity.com\/uploads\/images\/productpage\/B1xi-4.jpg\"\u003e\u003c\/center\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eUncompromisingly heavy mechanical design\u003c\/h3\u003e\n\u003cp\u003eThe inclusion of high-end elements such as the robust metal controls, extruded aluminium front panel, and a chassis crafted entirely from metal, the B1xi occupies an enviable position for discerning audiophiles seeking an unadulterated high-end amplifier.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ccenter\u003e\u003cimg src=\"https:\/\/www.musicalfidelity.com\/uploads\/images\/productpage\/B1xi-2.jpg\"\u003e\u003c\/center\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eNo WiFi on Purpose\u003c\/h3\u003e\n\u003cp\u003eThe B1xi remains committed to sound quality instead of WiFi, a display and an App. There is NO WiFi streaming on purpose. We’ve seen a surge in offerings from HiFi companies with all-in-one solutions and unfortunately, such developments are HUGLY EXPENSIVE and on top very maintenance heavy.\u003cbr\u003e\u003cbr\u003eConsequently, manufactures started to save the money somewhere: Cheap plastic cabinets, low-cost digital amplifiers, low-cost power supplies. Musical Fidelity stands for sound quality and robust design that lasts for decades. We INVEST our money and resources in top-tier hardware and the pursuit of optimal music reproduction. This means: Robust mechanics - Discrete circuits - Huge transformers - Class A\/B amps. Fast moving streaming technology is best kept separate and therefore will not negatively impact the lifecycle of the B1xi. For that reason, the B1xi features a high-quality isolated USB C 5V power output for your favorite modern streamer – effectively also doubling as a power supply upgrade for it.\u003c\/p\u003e\n\u003ch3\u003eThe Audiophile Truth\u003c\/h3\u003e\n\u003cp\u003eAny RF frequencies are influencing the performance of the analogue amplifier.
