In a new demonstration of his eexceptional vitality, The prestigious British firm Musical Fidelity has just expanded its reference series, the Nu-Vista, with another spectacular creation, this time an electronic one aimed at those who want to get the Get the most out of your vinyl records: the Nu-Vista Vinyl 2 phono preamplifier. Equipped with the unmistakable aesthetics of its range colleagues, this highly refined product has in the use of a hybrid architecture based on Nuvistor valves and Class A operation its “identifying” attribute. Compared to its predecessor, the celebrated Nu-Vista Vinyl, the new model now includes a fully balanced topology executed with discrete components, as well as three gain stages fed by a “solid state” circuitry configured in Class A. For its part, the equalization section is completely passive and is made up of two separate stagesan expensive and difficult solution to implement compared to the conventional one, but which ensures the most accurate possible representation of the ideal equalization curve, by providing a lower deviation with respect to the latter and better impedance matching. In addition, not only the standard RIAA curve is available, but also the less common Decca and Columbia.
Finally, the audio signals from the preamplifier are sent to a fully symmetrical Class A stage equipped with Nuvistors 7586 (4 in total). All subsystems described are mounted on a Printed circuit board (PCB) impeccably executed, which has been designed to minimize noise and distortion, also presenting a very low output impedance. Likewise, the balanced and unbalanced analog outputs They have their own stages, allowing the user to use them simultaneously. Another fundamental aspect of Nu-Vinyl 2 is the care taken in its power supplya reflection of Musical Fidelity’s continued commitment to its exclusive “Super Silent” transformers, characterized by the low saturation of its core and its extremely reduced magnetic radiation. Each discrete amplification stage incorporates a servo circuit DC, the preamplification section itself being excited by two symmetrical very low noise subsystems.
In turn, all balanced sources responsible for supplying energy to the Nuvistors are passively filtered and regulated, thus achieving a seamless treatment of the very delicate phono signals, features that can soon be improved with the addition of the optional external Nu-Vista Uni-PSU source. In the practical field, the new phono preamplifier Musical Fidelity’s reference product is at the level of a product in its category, offering the demanding user adjustment options particularly generous. Thus, the revenue can be selected between 40 dB and 63 dB (with the possibility of increasing each value available by 6 dB with the balanced connection), while in the case of moving coil (MC) capsules it is possible to select the iload impedance between 5 and 47,000 ohms. The Nu-Vinyl 2 is completed with a subsonic filter two-position to suppress possible subwoofer interference.
