New Tweaks for Musical Fidelity Nu-Vista Owners
Musical Fidelity has released a limited-edition NuVistor Tube ideal for Musical Fidelity owners looking to tweak and get the best performance from their products.
The sets, limited to just 200 worldwide, contains four selected Nuvistors, which according to the company, "guarantee a perfect interaction and audiophile sound due to their properties."
RCA invented Nuvistor tubes in the 1950s to solve the many shortcomings of conventional tubes. Unlike them, Nuvistor tubes are said to offer very high reliability, low microphony, low noise, consistency from batch to batch, small size, relatively low power consumption and great technical performance. The tube is made entirely out of metal and ceramic, with the complex manufacturing process requiring special equipment.
According to Musical Fidelity:
Nuvistors are among the highest performing small signal tubes. The results of huge life tests indicate that the lot failure rate per 1.000 hours for the 7586 (type used in MF) is only 0,475% at a confidence level of 95% to 10.000 hours. Unfortunately, just as uses for Nuvistor tubes were being explored, the transistor was invented, and it was 'game over' for Nuvistors.
With the technology lying dormant until about fifteen years ago, 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, they command very high secondhand prices because of their reported "beautiful sound, build quality and longevity."
The Musical Fidelity Nuvistor tubes are available now for £189 a set (4 tubes).

applause awards
Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.
Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.
The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.
We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
