Thank you for purchasing the Musical Fidelity -Vista . Nu PAM
Based on our excellent Nu-Vista 800 circuit we decided to go all out “fully balanced” on the Nu-Vista range.
The Nu-Vista PAM features the tried and tested Nu-Vista stage featuring 6S51N nuvistors in a discrete class
A amplier buer. This is followed by a balanced conguration circuit and balanced input high power, low
distortion “bridged” output amplier stage. The power stages have 2x 5 pairs of high power thermally
compensated output devices for reliable and stable operation. Based on Titan 1000W stage, it has separate
capacitors for bulk supply, and one each for output devices considerably 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 “standard” crossover distortion.
The Nu-Vista PAM comes with its own dedicated external power supply, the Nu-Vista PAM . To achieve PSU
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 ltering. This
quietens up the supplies and results in almost no mains-borne artefacts getting into the sensitive audio
circuitry.
Used properly and carefully, it should give many years of outstanding musical reproduction.
Dust regularly with a soft duster or soft brush, but be careful when using cleaning or polishing agents - they
may harm the surface nish.
The new Nu-Vista PAM and its PSU were a continued labour of love for Musical Fidelity. We are passionate
about what we do and passionate about Nuvistor tubes as we have always been. We hope that you derive as
much pleasure listening to the Nu-Vista PAM as we had creating it.
If there are any questions about the audio system, please consult the dealer, who is there to help and advis e.

other parts of the world.
