About Musical Fidelity M8xi

If you're seeking a high-end, sophisticated audio experience, look no further than the M8xi 550W Integrated Amplifier in sleek silver. This modern and stylish product from the reputable brand, Musical Fidelity, is the latest in a long line of Super Integrated Amplifiers, following the success of the A1000, NuVista M3, Tri Vista 300, kW500, M6/500i, NuVista 800, and NuVista 600.

The M8xi is a dual mono integrated amplifier, featuring a separate preamp with two monobloc power amps sharing a common chassis. Each component has its own heat sink and separate transformer, ensuring ultra-low impedance signals the moment they enter the amplifier. This design detail, coupled with twelve big bipolar transistors per channel, allows for an impressive 200 amps peak to peak.

The M8xi is not just about power; it's also about precision. The amplifier's new circuitry, developed over five years, delivers higher power, lower distortion, and better sound quality. The output stage efficiency has been increased, yielding about 10% more power for similar power supply voltage. The whole driver stage is pure Class A, contributing to a wider sound stage and more impactful micro and macro dynamics.

The M8xi also features a 5 input DAC, with its own power supply for added integrity. The DAC is based around the Texas Instruments PCM5242 TI low-distortion and low-noise DAC chip, supporting hi-res audio streams up-to 24-bit / 192kHz. All data streams are up-sampled and re-clocked by an internal converter to reduce jitter and remove unwanted artifacts in the sound.

The M8xi delivers 550 + 550wpc into 8 ohms, with distortion lower than 0.005% in the audible frequency range of 20 Hz to 20 kHz. It is unconditionally stable and will drive any loudspeaker with ease and ample power reserve. The precision volume control ensures perfect tracking right down to very low levels, achieved by laser-trimmed substrate resistors.

In terms of sound quality, the M8xi is effortless, fluid, and dynamic. It doesn't just sound loud, it sounds right. The dynamics are handled with no drama or fuss, and there is no distortion; just pure, undiluted music. It sounds like a superb small Class A amplifier but with limitless headroom. The M8xi 550W Integrated Amplifier is the perfect addition to any home or professional audio setup, offering a high-quality, sophisticated audio experience.
