Instructions for use
Thank you for purchasing the Musical Fidelity Nu-Vista PRE. Based on our excellent Nu-Vista 800 circuit we
decided to go all out “fully balanced” on the Nu-Vista range.
The Nu-Vista PRE uses a balanced configuration circuit and balanced precision matched stepped attenuator
for volume control. This means even at low volume levels, as well as higher, stereo imaging will be precise
and accurate. For driving strength, a pair of mini power amplifiers (equivalent to 50W) are used for the output
stages. They run in Class A for preamp purposes, giving the best in line driving capability, dynamic range, as
well as reduced noise and distortion inherently. Supply capacitance is generous, and chokes are added for
further improved supply ripple and pulse current spike reduction.
The Nu-Vista PRE 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.
Also included is the Nu-Vista remote control which is a solid
“Nu-Vista” style re-imagination of usual remote
controls. Machined from solid, it has the same feel as the front panel of the unit, has a powerful beam, and
runs off easily replaceable AAA batteries.
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
finish.
The new Nu-Vista PRE 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 PRE as we had creating it.
If there are any questions about the audio system, please consult the dealer, who is there to help and advise.
