New flagship of Musical Fidelity’s stereo preamplifiers, the Nu-Vista PRE is a spectacular electronics which concentrates all the know-how of the prestigious British firm in the processing of audio signals from line sources. Equipped with a opulent power supply dedicated that is housed in an attractive separate block and responds to the name Nu-Vista PRE PSUthe Nu-Vista PRE is based on the extraordinary and widely proven circuitry used in the Nu-Vista 800 model. This means that it includes a fully balanced topology in which the presence, in the input section, of an amplification stage based on nuvistors (the complex and unique device that gives its name to the Musical Fidelity reference series) 6S51N and configured in Class A.
This topology is complemented by a high precision balanced attenuator so that at both low and high volume levels the realism of the stereo image remains intact. The status of the Nu-Vista PRE as a product created without any type of compromise is also reflected with a extreme forcefulness in its exit section equipped with a pair of “mini power stages” (the equivalent of 50 watts, an exceptionally high figure for a preamplifier) also configured in Class A. This achieves maximize parameters as relevant in life-size musical reproduction as are the punch and dynamic rangeall accompanied by extraordinarily low noise floor and distortion.
It should also be noted a generous energy reserve through High-capacity, audiophile-grade capacitorsto which are added choke coils in order to improve the ripple of the power signal and reduce current peaks. Identical level of demand exhibited by the power supply Nu-Vista PRE PSUpresented in an imposing independent metal enclosure in which, in addition to the power circuitry itself, they have been included filter networks for both the incoming and outgoing signal. Thanks to this design, it is achieved further increase the silence level of the different power supply lines, the result being the virtual elimination of artifacts present in the network signal that could affect the sensitive audio circuitry. Musical Fidelity’s new reference stereo preamplifier comes complete with an elegant remote control manufactured from precision machining from a solid block of metal.
