The Musical Fidelity NU-VISTA Series now presents itself in the latest generation, whereby the Musical Fidelity NU-VISTA PAS naturally plays a central role, since it is a stereo power amplifier which, as a partner to the also new preamplifier Musical Fidelity NU-VISTA PRE, appeals to many hi-fi enthusiasts. Especially since the latest generation of the Musical Fidelity NU-VISTA Series, according to the English hi-fi manufacturer Musical Fidelity, is not to be understood as an evolution, but rather as a revolution and raises the quality of these solutions to a completely new level. Musical Fidelity NU-VISTA PAS – A whole new level of quality The new Musical Fidelity NU-VISTA PAS Stereo Power Amplifier is the new high-end power amplifier in the Musical Fidelity NU-VISTA Series. X Series launches with X-10D Class A triode line stage: ‘the most dramatic sonic enhancement you’re likely to hear!’ (F1). X-Ray CD player launched. Described as ‘the sort of object you just want to fondle’ (Hi-Fi News) ‘a thrilling, substantial and satisfying listen’ (What Hi-Fi?) and ‘Hi-Fi meets nuclear warhead’ (T3).

Next up: kW 500 super integrated amp with twin-triode tubes. Hi-Fi News said, ‘For one rare reviewing occasion I could not find a thing to fault about the musical presentation of an amp’. In contrast to tubes of classical design, nuvistor tubes were supposed to convince with a very high reliability, low sensitivity to microphonics, low noise, a high consistency from batch to batch, a small size and last but not least a comparatively low power consumption. Line-up expands to meet every hi-fi need and budget. Highlights include the AMS CD/DAC – our finest digital product yet - and AMS100, the world’s most advanced pure Class A amp You may also like…

The Nu-Vista 600 has the benefit of the Nu-Vista valve preamp stage. The preamp is directly coupled to the input stage so you have shorter signal paths, we have an improved psu over the M6si. Given what has been stated in this thread it would seem nuvistors are worthy of consideration, but certainly not the be-all-end-all. I was perhaps hopeful to learn or field opinions that it could offer traditional vacuum tube sound without the negatives, whatever the traditional sound (if any) and negatives (if any) happen to be. And its already been pointed out (here and/or elsewhere) that there is no tube sound per se and everything has negatives. The aim was to combine a warm, musical sound with the corresponding power potential, and this is exactly what the Musical Fidelity NU-VISTA Series has always been known for, and in the latest generation it is supposed to do with flying colours. Nuvistor tubes – The alternative to conventional tubes

The Musical Fidelity NU-VISTA Series has always been exceptional, and this is even more true of the latest generation of systems such as the new Musical Fidelity NU-VISTA PAS. New M1 CLiC unites analogue and digital sources under universal control. Wins European Network Music Player, EISA Awards 2011-2012.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. Debut of Nu-Vista M3 pre/power amp, including discrete Nu-Vista power amp modules with choke regulation. ‘This is what hi-fi should be all about’ (Gramophone). Futuristic CD-PRE 24 arrives, combining a high-quality CD transport, DAC and preamp. On Hi-Fi says it ‘represents a combination of features, functional performance and affordability that seems an audiophile dream come true’. AltaVista was already starting to falter by the time the NudeVista domain was registered. The former search giant finally shuttered in 2013. Meanwhile, NudeVista has continued to grow, both in their userbase and catalog of dirty, filthy porno. The younger wankers don’t even remember AltaVista, but NudeVista is currently encouraging nearly 30 million crank sessions a month. 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 developers’ declared aim was to fully live up to the claim that Antony Michaelson, the founder of Musical Fidelity, had always pursued, namely to realise an audio system that sounded like tube and Class A amplifier systems, but at the same time had the power to realistically reproduce music in all its dynamics. 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 greattechnical performance. The tube is made entirely out of metal and ceramic, with the complex manufacturing process requiring special equipment. The heart of the latest Musical Fidelity NU-VISTA Series is once again the so-called Nuvistor tubes. These were developed in the 1950s with the aim of eliminating the shortcomings of conventional tubes.They approached each new design by looking for the absolute best solution to a given challenge and embrace new technologies in our designs as well as developing more traditional methods for even greater performance. Supercharged X-DAC V8 introduced, with switchable tube buffer and extra-heavy-duty power supply. ‘For its superb performance as a detailed, sweet-sounding DAC, the X-DAC V8 stands on its own’ (Stereophile).

It is remarkable that Musical Fidelity now uses a separate power supply, the Musical Fidelity NU-VISTA PAS PSU. This allows the developers to keep the sensitive signal processing completely free of disturbing influences and to draw from the full range of power supply options without having to compromise in any way.The new Musical Fidelity NU-VISTA PAS delivers two times 300 watts into 8 ohms, two times 500 watts into 4 ohms and 1,000 watts peak power into 2 ohms.
