Musical Fidelity Nu-Vista PRE hi-end stereo preamplifier silver

Nu-Vista PRE Power Supply

The Nu-Vista PRE comes with a dedicated external power supply.

For the best noise performance, we have removed the AC mains supply from the head unit and placed it in a separate matching box. In this box we have used the extra space to fit an integrated mains and output filter. This reduces noise from the power supplies and ensures that almost no mains-borne artefacts enter the sensitive audio circuitry.

The power supply has ON/Standby LEDs and is controlled from the front panel of the head unit. If full isolation from the mains is required, the power supply also has a rear mounted mechanical rocker switch for complete shutdown. Also included is the Nu-Vista remote control which is a solid ‘Nu-Vista’ take on the usual remote controls. Machined from solid, it has the same feel as the unit's front panel, has a powerful beam and runs on easily replaceable AAA batteries.

Build Quality

The mechanical construction of the Nu-Vista PRE is uncompromisingly rigid and solid, in typical Musical Fidelity tradition. The front panel and side panels are milled from extruded aluminum profiles and are extremely massive.

The separate Nu-Vista PRE PSU houses all the transformers, which by nature generate mechanical vibrations and radiate harmful electromagnetic fields. Here they are as far away as possible from the critical amplifier circuits. This contributes significantly to a very good signal-to-noise ratio. The Nu-Vista PRE is fundamentally immune to the effects of vibrations from the environment. The same can be said about electromagnetic immunity. The massive aluminum case acts as a Faraday cage. It protects the internals from external electromagnetic fields and, equally, the rest of your hi-fi equipment from the electromagnetic fields generated by the Nu-Vista PRE and PRE PSU.
