When matched with the Nu-Vista PRE, the sound performance is unrivalled and can comfortable match any luxury high-end system.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTo 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eElsewhere 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.\u003c\/p\u003e\n\u003ch2\u003ePAS Power Supply Included\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Type:\u003c\/strong\u003e Stereo Power Amplifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Class:\u003c\/strong\u003e A-B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output (8Ω):\u003c\/strong\u003e \u0026gt; 300 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Voltage Output:\u003c\/strong\u003e 49V RMS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Current Output:\u003c\/strong\u003e 130A Peak to Peak\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Devices:\u003c\/strong\u003e 5 Pairs per-channel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel Separation:\u003c\/strong\u003e \u0026gt; 96\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping Factor:\u003c\/strong\u003e 200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValves:\u003c\/strong\u003e 8 x 6S51N Nuvistors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal To Noise Ratio:\u003c\/strong\u003e (A-Weighted) \u0026gt; 108 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD +N:\u003c\/strong\u003e Typical \u0026lt; 0.003 %\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA Input(s):\u003c\/strong\u003e 2 Stereo Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Impedance (Unbalanced Input):\u003c\/strong\u003e 100000 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced XLR Input(s):\u003c\/strong\u003e 2 Stereo Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed Analogue Output(s): \u003c\/strong\u003e1 x RCA Pair, 1 x XLR Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrigger Connection:\u003c\/strong\u003e Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply Weight:\u003c\/strong\u003e 40 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Power Consumption:\u003c\/strong\u003e 1060 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional Dimensions (W x H x D):\u003c\/strong\u003e (PSU) 483 x 187.5 x 478 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W x H x D):\u003c\/strong\u003e 483 x 187.5 x 494 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 27 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFurther Information\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.nuvista-audio.com\/wp-content\/uploads\/2026\/07\/MF-NuVistaPAS-EN.pdf\" target=\"_blank\" title=\"Nu-Vista PAS - Product Information (PDF)\" rel=\"noopener\"\u003eNu-Vista PAS - Product Information (PDF)\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.nuvista-audio.com\/wp-content\/uploads\/2026\/07\/Nu-Vista-PAS-manual-issue-1.pdf\" target=\"_blank\" title=\"Nu-Vista PAS - User Manual (PDF)\" rel=\"noopener\"\u003eNu-Vista PAS - User Manual (PDF)\u003c\/a\u003e\u003c\/p\u003e","brand":"Musical Fidelity","offers":[{"title":"Black","offer_id":57033708437890,"sku":"nu-vista-pas-psu-black","price":21999.0,"currency_code":"GBP","in_stock":true},{"title":"Silver","offer_id":57033708470658,"sku":"nu-vista-pas-psu-silver","price":21999.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0260\/8588\/3938\/files\/musical-fidelity-nuvista-pas-silver.jpg?v=1794566041","url":"https:\/\/studioincar.co.uk\/products\/musical-fidelity-nu-vista-pas-power-amplifier-pas-psu","provider":"Studio Incar","version":"1.0","type":"link"}
