A Class Apart

Nu-Vista PAM boasts a balanced configuration circuit along with a balanced input high power, low distortion bridged output amplifier stage. Power stages utilize 5 pairs of high-power, thermally-compensated output devices ensuring steadfast performance. Mirroring the Titan 1000W stage, it includes separate capacitors for bulk supply and each output device, culminating in enhanced dynamics and lowered output impedance.

Uncompromised Power

The Nu-Vista PAM is accompanied by its own external power supply, set up in a distinct box to lower noise intrusion. By leveraging additional space for in-built mains and output filtering, we minimize mains-borne artefacts reaching the sensitive audio circuitry. This isolated power supply enhances overall audio performance and provides easy control with its ON/Standby LEDs, controllable directly from the main unit.

Built to Impress

The construction of the Nu-Vista PAM is relentlessly solid, staying true to the Musical Fidelity tradition. The front panel and side panels, crafted from extruded aluminium profiles, offer impressive sturdiness. The dedicated Nu-Vista PAM PSU shields critical amplifier circuits from mechanical vibrations and harmful electromagnetic fields, resulting in superior signal-to-noise ratio and protecting the rest of your hi-fi gear.

Reviving the Nuvistor Legacy

The integration of Nuvistor tubes with state-of-the-art fully balanced technology is a first in hi-fi history. The Nu-Vista PAM and Nu-Vista PAM PSU deliver unparalleled technical performances, embodying a sound that’s as incredible as it’s measurable – silky smooth with enormous transients and an effortless feel that’s both relaxing and involving.

Nuvistor tubes, birthed in the 1950s to address the shortcomings of conventional tubes, present high reliability, low microphony, low noise, consistency from batch to batch, and excellent technical performance. Despite being overshadowed by the advent of transistors, Nuvistor tubes found new life about fifteen years ago, thanks to Musical Fidelity’s groundbreaking Nu-Vista series.

The Nu-Vista PAM is a testament to our passion for Nuvistor tubes and our commitment to quality. We trust you’ll find as much pleasure in listening to the Nu-Vista PAM as we did in its creation. Experience a sound so tangible; it’s almost touchable.
