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.
Musical Fidelity has been designing and manufacturing Hi-Fi electronics for over thirty years and has become one of the best-known brands in the Hi-Fi industry. Driven by a passion for wonderful music and the challenge of world-class engineering Musical Fidelity approached each new design by looking for the absolute best solution to a given challenge and embrace new technologies in their designs as well as developing more traditional methods for even greater performance.
