Musical Fidelity Nu-Vista 800.2 - Integrated Amplifier
Choose options
The Nu-Vista 800 was an amplifier that enjoyed much popularity and use as a high-end hybrid integrated in recent years. Unfortunately, as with all things that comprise modern technology, as well as more traditional, parts were discontinued. The original "retro look" display was suddenly discontinued at very short notice.
We were therefore left with a choice: discontinue a popular amplifier or an alternative solution and replace the original with an updated version but as unchanged as possible from the original formula.

Superb design, heroic build quality
Never before in the history of hi-fi have Nuvistor tubes been combined with cutting edge SMD technology and sophisticated modern design techniques. The technical performance of the Nu-Vista 800.2 is astonishing.
More than 300 watts per channel with unconditional stability margins and incredible load driving capacity.
Incredibly low distortion across a colossal bandwidth.
Extremely quiet.
Extremely flat frequency response.
The Nu-Vista 800.2 measures like a dream, but more importantly, it sounds incredible. It’s silky smooth, with huge transients and an easy feel that’s both relaxing and engaging. Note in particular how the Nu-Vista 800.2 projects images between the speakers so you can almost touch them.
The Legacy of the TITAN
The Nu-Vista 800 has been an amplifier that has enjoyed much popularity and use as a high-end hybrid integrated amplifier in recent years. It was originally designed in 2013 to revive the then discontinued Nu-vista product family.
We reworked the old Nu-Vista circuit to modern practices and it was the first to include a locally decoupled output stage since the TITAN. This involved assigning each output device to a corresponding high current bulk supply capacitor. These capacitors mounted on the power amplifier PCB give it a "V10" engine look!
Mounting such a capacitor close to each output transistor allows more immediate access to the stored energy, with a much lower impedance path to traverse. This results in improved transient response while also providing improved ripple filtering at higher currents in combination with power capacitors located elsewhere.
The main power capacitors are located right on the rectifiers, also decreasing the power supply impedance and helping keep rectification and hum noise away from the high-gain PA circuit.
This unit was very popular, bringing the Nu-Vista sound to a new generation of listeners and a matching CD player was also produced, which also received great acclaim.
From Nu-Vista 800 to 800.2
Unfortunately, as with all things modern technology, as well as more traditional, parts have been discontinued. The original "retro look" display was suddenly discontinued at very short notice. We were then left with a choice: discontinue a popular amplifier or an alternative solution and replace the original with an updated version that is as unchanged from the original formula as possible.
The Nu-Vista 800.2 has received a new, modernized faceplate and a completely new display. It is in line with our new Nu-Vista product range. We quickly realized that we would need to update the power circuitry, control circuitry and electronic on/off control to accommodate the new display. Fortunately, this also meant we could add the missing remote on/standby feature.
And while we were at it, we rewound our transformers, for lower steady state flux, so they are less susceptible to DC offset noise from the mains. This means a slightly larger (and heavier) transformer that, thankfully, still fits in the same case.
The result is that we now have a new hybrid integrated amplifier, the Nu-Vista 800.2, which will visually fit into the new Nu-Vista product range, while keeping the audio parameters of the original intact, and even improving them in some areas.
Heroic build quality
The mechanical construction of the Nu-Vista 800.2 is uncompromisingly rigid and solid, in typical Musical Fidelity tradition. The front panel and side panels are milled from extruded aluminium profiles and are extremely massive. The Nu-Vista 800.2 is essentially immune to the effects of ambient vibrations. The same can be said for electromagnetic immunity. The massive aluminium case acts as a Faraday cage. It protects the internal parts from external electromagnetic fields and, equally, the rest of your HiFi equipment from the electromagnetic fields generated by the Nu-Vista 800.2.
The new Nu-Vista 800.2 is the result of an ongoing labor of love for Musical Fidelity. Our passion for Nuvistor tubes has not stopped. Everyone at Musical Fidelity hopes that listening to the Nu-Vista 800.2 will give you the same pleasure that we did while creating it.
Nuvistor Tubes
Nuvistor tubes were invented in the 1950s to solve the many shortcomings of conventional tubes. Unlike them, Nuvistor tubes offer very high reliability, low microphony, low noise, batch-to-batch consistency, small size, relatively low power consumption and great technical performance.
A famous application was the Ampex MR-70, an expensive studio tape recorder whose entire electronics were based on nuvistors. Another limited application of this very small tube was in studio microphones of the era, the AKG/Norelco C12a, using the 7586, being a good example.
It was later found in the famous Neumann U 47 studio microphone. This microphone was highly regarded by artists all over the world and was used by many top recording artists such as Frank Sinatra, The Beatles and so on. Amazingly, you can currently see a U47 microphone, with its stand, cables and power supply on eBay for $10,999 "Buy It Now".
Unfortunately, just as the uses of Nuvistor tubes were being explored, the transistor was invented and the Nuvistors were out of business. That remained the case until about fifteen years ago when Musical Fidelity created the first of their innovative Nu-Vista series. These legendary limited edition products sold out within months. Today, fifteen years later, they command very high second hand prices due to their beautiful sound, build quality and longevity.
