Products that are Awaiting Stock are items that we would normally carry on stock at our Oxfordshire warehouse, but are currently unavailable. Chances are there is already more on the way, but if you would like a more accurate availability status please feel free to Contact Us.
Urgent order items are products that we do not normally carry on stock, but they are typically held on stock by our European suppliers. Depending on availability, we will seek to order these products quickly, when we have an enquiry. They can therefore be subject to quicker availability times than "Special Order" products.
Special Order items are those that are most often built to order. For these items, we tend to experience longer lead times as we negotiate them into the production line with our suppliers.

The Nu-Vista PAS is a fully balanced, Class A stereo power amplifier that combines, for the first time, fully discrete circuitry with Musical Fidelity’s iconic nuvistor valve stage and a separate power supply in a matching chassis. When matched with the Nu-Vista PRE, the sound performance is unrivalled and can comfortable match any luxury high-end system.
To achieve its unique sound signature, the Nu-Vista PAS features eight (four per-channel) 6S51N nuvistor valves in a discrete, Class A amplifier buffer stage; but there is so much more going on inside this stylish chassis to ensure it delivers reference-grade sound.
The Nu-Vista PAS features fully balanced circuitry and a high power, low distortion output amplifier stage. The amplifier power stage features five (5) high-power, thermally compensated output devices per-channel for reliable and stable operation. Inspired by the iconic Musical Fidelity Titan amplifier, it has separate capacitors for bulk supply, and one each for the output devices, considerably reducing output impedance and improving dynamics.
Elsewhere in the circuitry, chokes are added for further-improved supply ripple. Pulse current spike reduction bias is set for over 5W of initial Class A operation that slides into Class B operation at the point where the lower discontinuity is easier dealt with than “standard” crossover distortion.
The Nu-Vista PAS PSU allowed Musical Fidelity’s engineers to remove the AC mains power supply from the main unit and place it in a separate, spacious chassis dedicated to delivering perfect power. Featuring inbuilt mains and output filtering, it functions as a very quiet, clean power supply that allows the sensitive audio circuitry in the Nu-Vista PAS to perform without mains-borne interference, far away from the optimised power transformers. For total convenience in use, the Nu-Vista PAS PSU is switched on and off via the Nu-Vista PAS’s front-panel.
In typical Musical Fidelity style, the overall construction of the Nu-Vista PAS and Nu-Vista PAS PSU is uncompromisingly solid. The front and side panels are milled from extruded aluminium profiles, contributing to a chassis that effectively acts as a Faraday cage, protecting the internal circuitry from external electromagnetic fields. Because of the overall weight, the chassis is also resistant to other mechanical vibrations and airborne interference.
The Nu-Vista PAS represents a first for Musical Fidelity. Its technical performance and measurements are astonishing and truly class leading. But more importantly this all results in a sound that is like nothing else. It is silky smooth with enormous transients and an effortless feel that is at once relaxing and involving. When combined with the matching pre-amplifier, they project an image between the loudspeakers that is so real, you could almost touch it.
Musical Fidelity Nu-Vista PRE/PAS & PSUs
"The sound is all about character and performance, as is clear with Peter Gabriel’s near-impersonation on the title track of the superb Here It Is Leonard Cohen tribute album [Blue Note 00602445659951] - the recording is closely detailed, and these amplifiers let every detail of that intimacy flood out, delivering a chilling sense of presence in the room."
Musical Fidelity Nu-Vista PRE and PAS amplifiers review
"Their build is as first class as you’d hope for at this price, but it’s in the sonic stakes where they really excel, with power, dynamics and effortless control combined with imaging and a sense of organic realism, that makes them a comparative high-end bargain compared to the competition. "
Henley Says...
When HiFi separates are the name of the game, none do it with quite as much impact as Musical Fidelity. The PRE, PAS and PAM models feature pure HiFi excellence, separated out into one box per task. The result is a physically commanding system with a presence that shouts of your level of seriousness when it comes to your musical reproduction. And this doesn't even consider the sound! The audio performance is truly something to behold, and we try our utmost to find any excuse to hear them - keep an eye out for us at HiFi shows up and down the country.
