Musical Fidelity Nu-Vista 800 Integrated Amplifier


In terms of tone quality, texture, transient attack, sustain, and decay, the Nu-Vista painted a consistent, coherent picture. ... In short, the Nu-Vista 800 drew me in. That was what mattered.


The Nu-Vista 800 is a power-house of an amplifier with outstanding clarity and finesse

The Nu-Vista 800 measures like a dream but, more importantly, it sounds incredible. It is silky smooth with enormous transients and an effortless feel that is at once relaxing and involving. Of special note how the Nu-Vista 800 projects images between the loudspeakers so that you can almost touch them.

The new Nu-Vista 800 was a labour of love for Musical Fidelity. We are passionate about what we do and passionate about Nuvistor tubes. Everyone at Musical Fidelity hopes that you derive as much pleasure listening to the Nu-Vista 800 as we had creating it.

Nuvistor Technology

Nuvistor tubes were invented in the 1950s to solve some shortcomings of conventional tubes. Nuvistor tubes offer very high reliability, low microphony, low noise, consistency from batch to batch, small size, relatively low power consumption, and great technical performance.

Unfortunately just as uses for nuvistor tubes were being explored, the transistor was invented and it was game over for nuvistors.

There the matter rested until about fifteen years ago, when Musical Fidelity created the first of its ground-breaking Nu-Vista series. These legendary, limited-edition products sold out in a matter of months. Today, fifteen years later, they command very high second-hand prices because of their beautiful sound, build quality, and longevity

Never before in the history of hi-fi have Nuvistor tubes been coupled with state-of-the-art SMD technology and sophisticated modern design techniques. The Nu-Vista 800’s technical performance is astonishing.
