Musical Fidelity Nu-Vista PRE Pre-amplifier Class A Black

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.

To achieve better noise performance, Musical Fidelity removed the AC mains power supply from the main unit and built it into another matching box. In this box Musical Fidelity 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.

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 significantly contributes to great signal to noise ratio. The Nu-Vista PRE is basically immune against the effects of vibration from the environment. The same can be said about electro magnetic immunity. The massive aluminium case acts as a Faraday cage. It protects the internals against outer electromagnetic fields, and in the same way, the rest of your hi-fi gear against electromagnetic fields generated by the Nu-Vista PRE & PRE PSU.

The Legendary Nu-Vista Stage: Never before in the history of hi-fi have Nuvistor tubes been coupled with state-of-the-art fully balanced and discrete technology and sophisticated modern design techniques. The Nu-Vista PRE & Nu-Vista PRE PSU‘s technical performances are astonishing. They measure like a dream but, more importantly, sound incredible. Silky smooth with enormous transients and an effortless feel that is at once relaxing and involving. Of special note how they project images between the loudspeakers so that you can almost touch them.

The Nu-Vista PRE and its PSU were a continued labour of love for Musical Fidelity. Musical Fidelity are passionate about what they do and passionate about Nuvistor tubes as they have always been. Musical Fidelity hope that you derive as much pleasure listening to the Nu-Vista PRE as they had creating it.
