NU-VISTA 800 world class integrated amplifier in stock 
New and demo avialable, call or email for pricing.  


The Nu-Vista 800 super integrated is at the pinnacle of
Musical Fidelity’s art. It offers superlative sound quality, huge power
reserves, exceptional technical performance, finely engineered build quality
and outstanding value. The Nu-Vista 800 uses the nuvistor sub miniature tube.
It employs state of the art; circuit design, PCB layout, SMD technology and
programming to deliver a thrilling combination of fine, detailed sound quality
with no harshness or grain but at the same time have massive undistorted power
reserves. All in all the Nu-Vista 800 gives a deeply satisfying and convincing
musical performance.For us at Musical Fidelity that’s what it’s all about.

Nu-Vista 800 -

For the first time in the history of hi-fi, Musical Fidelity
have combined nuvistor technology with Surface Mount Design and CAD/CAM PCB
concepts. The aim of this large undertaking was to create an ultimate super
integrated amplifier. The result is extraordinary technical and sonic

For Musical Fidelity, the NuVista 800 integrated was a
labour of passion and love. We have tried to achieve the absolute maximum
performance from every part of the circuit.

The NuVista 800 integrated offers full-on, high-end
performance, in a beautiful, relatively compact package, and gives a
comfortable 300 watts per channel.

The NuVista 800 delivers everything that its concepts
promise. On the one hand, you have the beauty and warmth of nuvistor tubes.
However, because of their superlative technical performance, there is no
colouration or excessive warmth.

On the other hand, there is a huge power amp with massive
reserves of power and current that has the delicacy and speed of attack (and
decay) of a small triode power amp but, just you wait for that transient: it is
delivered effortlessly with no colouration or limits.

The NuVista 800 sound quality is, to us at least, totally
satisfying.Beautiful, deep and wide sound staging, effortless transients,
incredible bottom end extension, speed, rhythm and then the exquisite mid
range. We believe that this is what hi-fi is about.

Nu-Vista 800 - Design and Build

Fifteen years ago, Musical Fidelity were the first company
in the world to use nuvistor tubes for their high-end NuVista series. The
original NuVista series (NuVista pre amp, NuVista M3 integrated, NuVista 300
power amp and NuVista 3D CD player) created a sensation when they were launched
in 1999. They gave an almost perfect balance between state of the art
transistor and tube design.

Because there were only limited tube bases available in
1999, the NuVista series were all made in limited editions.Their reputation is
legendary and, to this day, used NuVista series products for very high prices.

Background on nuvistors


Nuvistor tubes were designed in the late 1950s. Their design
process took into account all the criticisms and weaknesses of the standard
glass tubes that had gone before. As a result, nuvistor tubes offered:

Unprecedented reliability

Compact size

Very low microphony

State of the art technical performance

Total consistency between manufacturing batches

Indeed, nuvistors were the ultimate, high performance,
triode tube. Unfortunately for them, transistors were just coming of age as
nuvistors became available.

A bright new dawn


For at least three years after the launch of the original
NuVista series, Antony Michaelson tried to get more tube bases. Nuvistor tubes
were plentiful but bases were impossible to obtain. After a time, he stopped

As many of you know, Antony Michaelson is persistent. About
eighteen months ago, he started thinking about NuVistas again. This time,
things were different.

Via the internet, he was able to locate what are probably
the last nuvistor bases on this planet Earth. Antony was thrilled. He purchased
all that could be found.

This made it possible for Musical Fidelity to realise their
dream of manufacturing more nuvistor-based products, including the new mega
super integrated, the NuVista 800.

This time, they would be able to combine their state of the
art NuVista technology with their state of the art Surface Mount Design PCB
techniques, and the new designs would benefit from the freedom of layout that
they offer.

General description

The NuVista 800’s front end is positioned on the same PCB as
the input circuitry. This keeps all PCB tracks as short as possible, and
ensures that this highly sensitive function is at right angles to any stray
hyseresis field from the transformers, ensuring superlative sonic performance.

The nuvistor stage itself combines nuvistor tubes with our
exclusive Surface Mount Design and technology systems. This allows them to
perform at a level never seen before.

The power amp stage is derived from our monster Titan amp,
regarded by many as one of the best amplifiers ever made. However, they have
made subtle improvements to the circuit, squeezing even more performance from
what was already a legendary circuit design.

The overall configuration is dual mono, with a separate 1.5
kV, super silent drive mains transformer per channel.

The result -maximum performance from every part of the
circuit- clearly shows just how much of a labour of love and passion for the
NuVista 800 was for us.

Technical performance

The NuVista 800 delivers a comfortable 300 wpc. It is
capable of truly massive current swings: about 200 Amps peak to peak. In a
word, vast. Distortion at 1kHz is vanishingly low at 0.002%. At 10 kHz, it is
about 0.003% and at 20 kHZ 0.004%. These are extraordinary figures. More
astonishingly is the distortion into 4 Ohms (1kHz) is its exactly the same is
into 8 Ohms.

NuVista 800 has very low noise and excellent stereo

Because of its huge peak current capability, it can drive
any speaker with any cable, without breaking a sweat.

NuVista 800 combines the beauty, delicacy and poise of state
of the art tube and semiconductor design blended with massive power and
