The Musical Fidelity Nu Vista PAS Power Amplifier stands out with its innovative design and cutting-edge features, making it a must-have for any serious audio enthusiast. At its core, the amplifier integrates Nuvistor tubes—a technology pioneered in the 1950s to overcome the limitations of conventional tubes.

These tubes offer low noise, high reliability, and exceptional performance, delivering a silky-smooth sound with a natural warmth that’s hard to replicate. Paired with a fully balanced and discrete circuit design, the Nu-Vista PAS ensures minimal distortion and maximum audio fidelity, making it a perfect fit for any hi-fi stereo sound setup.

Another standout feature is its high-power output, capable of delivering over 300W into 8 ohms, 500W into 4 ohms, and an impressive 1000W peak into 2 ohms. This ensures that even the most demanding speakers are driven with ease, providing a robust foundation for your home cinema or hi-fi setup. The amplifier also features a dedicated external power supply unit (PSU), which houses all transformers and includes advanced mains and output filtering.

This design choice significantly reduces noise and electromagnetic interference, ensuring that the sensitive audio circuitry remains free from mains-borne artefacts, resulting in a cleaner, more precise sound.
