The <strong>Nu-Vista PAM<\/strong> features the tried and tested <strong>Nu-Vista<\/strong> stage featuring 6S51N nuvistors in a discrete class A amplifier buffer.<\/p>\n<p>This is followed by a balanced configuration circuit and balanced input high power, low distortion \u201cbridged\u201d output amplifier stage. The power stages have 2x 5 pairs of high power thermally compensated output devices for reliable and stable operation. Based on the Titan 1000W stage, it has separate capacitors for bulk supply, and one each for output device, reducing output impedance and improving dynamics. Chokes are added for further improved supply ripple and pulse current spike reduction. Bias is set for over 5W of initial class A operation thereafter the stage slides into class B operation at a point where the now much lower discontinuity is easier dealt with than \u201cstandard\u201d crossover distortion.<\/p>\n<p>The <strong>Nu-Vista PAM<\/strong> comes with its own dedicated external power supply. To achieve better noise performance, we removed the AC mains power supply from the main unit and built it into another matching box. In this box we took advantage the extra space to set up inbuilt mains and output filtering. This quietens up the supplies and results in almost no mains-borne artefacts getting into the sensitive audio circuitry. The Power supply has ON\/Standby LEDs and is controlled from the main unit front panel. If total mains isolation is required, the power supply also has rear mounted mechanical rocker switch for full power off.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-34254\" src=\"https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/09\/Musical-Fidelity-NU-VISTA-PAM-Mono-Power-Amplifier-desc.jpg\" alt=\"\" width=\"1290\" height=\"450\" srcset=\"https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/09\/Musical-Fidelity-NU-VISTA-PAM-Mono-Power-Amplifier-desc.jpg 1290w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/09\/Musical-Fidelity-NU-VISTA-PAM-Mono-Power-Amplifier-desc-400x140.jpg 400w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/09\/Musical-Fidelity-NU-VISTA-PAM-Mono-Power-Amplifier-desc-768x268.jpg 768w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/09\/Musical-Fidelity-NU-VISTA-PAM-Mono-Power-Amplifier-desc-430x150.jpg 430w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/09\/Musical-Fidelity-NU-VISTA-PAM-Mono-Power-Amplifier-desc-700x244.jpg 700w, https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/09\/Musical-Fidelity-NU-VISTA-PAM-Mono-Power-Amplifier-desc-150x52.jpg 150w\" sizes=\"auto, (max-width: 1290px) 100vw, 1290px\" \/><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The <strong>Nu-Vista<\/strong> by <strong>Musical Fidelity<\/strong> range also features the <strong>Nu-Vista PAM<\/strong>, which takes the <strong>PAS<\/strong> design and separates it into fully separated monoblock amplifiers.
