A striking result of rigorous work based on the mastery of electronic technology applied to sound reproduction without compromise. This gives us the veteran and respected british company Musical Fidelity with the Nu-Vista 600.2 stereo integrated amplifiera sensational electronic that draws on three of its elite achievements: the Nu-Vista PRE preamplifier and the Nu-Vista PAS (stereophonic) and Nu-Vista PAM (monophonic) power stages. Developed by the team led by Simon QuarryTechnical Director and Chief Designer of Musical Fidelity, this impressive amplifier with rigorously double monophonic architecture It has been possible thanks to a much more in-depth review than the one applied at the time so that its older brother, the imposing Nu-Vista 800.2, saw the light. Compared to the Nu-Vista 600 the Nu-Vista 600.2 now benefits from a power amplification section inspired by that of the British firm’s formidable Titan model, locally decoupled output stage included.
For its part, the circuit board topology printed It has been drastically revised, while the electrical and electronic components have been updated. The same is also used mechanized volume control by laser than on the Nu-Vista 800.2 and the power supply It has been substantially modernized, with two oversized toroidal transformers, multiple power supply lines and high-precision filtering of the preamplification and power amplification sections. In parallel, the arrangement of the different subsystems has been significantly reorganized with the objective earn on benefits and save space, having added a exit game balanced preamps and the incorporation of separator stages on all line outputs to eliminate possible interference between devices connected to any of the aforementioned pre-outputs. As for what is undoubtedly one of the identifying elements of Nu-Vista 600.2, the Nu-Vista stage, it is located in the top printed circuit board and is identical to that of the aforementioned PRE, PAS and PAM models, therefore mounting nuvistors 6S51N in a separator amplifier made with discrete components and configured in Class A.
In this regard, it should be noted that the preamp, nuvistor and input circuits (with selection by high quality relays) are now completely double monophonic with separate power supply for left and right channels. Equipped with 4 transistors With high power and high current per channel, the Musical Fidelity supplies 2×160 watts continuous over 8 ohms or 2×300 watts continuous over 4 ohms, as well as 2×500 peak watts over 2 ohms, figures that in combination with a current delivery capacity 50 amps from peak to peak enable it to attack even the most “difficult” speakers with exceptional ease. The Nu-Vista 600.2 is completed with an aesthetic matching that of its range mates and a robust and meticulous mechanical constructionwith extruded aluminum front and side panels that not only virtually immunize it from any vibration coming from the surrounding environment, but also from external electromagnetic fields.
