The Nu-Vista 600.2 is a fully analogue, discrete integrated amplifier with dual-mono circuitry and premium components throughout. Representing the very best of luxury high-end audio, this is a complete solution that is easy to integrate with a wide range of high-end sources and loudspeakers.  

To achieve its unique sound signature, the Nu-Vista 600.2 features four 6S51N nuvistor valves in a discrete Class A amplifier buffer. These tubes are installed on a newly designed PCB, alongside the sophisticated pre-amplifier stage, on a self-screening tray that is mounted above the main amplifier circuitry, for better isolation and reduced noise. The pre-amplifier, nuvistor stage, and the input circuits are all fully dual mono, with separate power supplies for each channel. 

The benefit of this new top-layer PCB design is that there is more space in the chassis for connections, so the Nu-Vista 600.2 boasts six stereo inputs, including two balanced XLR inputs. There are also three stereo output options, including a balanced XLR variable output, which are each separately buffered, so there is no interference between the different outputs.

The power amplifier stage has been designed to mimic a V4 engine, with four output transistors per-channel, delivering 160W into 8. Inspired by the iconic TITAN amplifier, the output stage couples each individual output device to its own high-current bulk supply capacitor. This configuration allows for more immediate access to stored energy and much lower impedance in the signal path, resulting in better technical measurements and low distortion, meaning the music can sound exactly as the artist originally intended.  

In typical Nu-Vista by Musical Fidelity style, the overall construction of the Nu-Vista 600.2 is uncompromisingly solid. The front and side panels are milled from extruded aluminium profiles, contributing to a chassis that effectively acts as a Faraday cage, protecting the internal circuitry from external electromagnetic fields. Because of the overall weight, the chassis is also resistant to other mechanical vibrations and airborne interference. 

Sitting between the Nu-Vista 600.2s two over-sized control knobs is a large, clear display with different view options, including a stylish VU-meter option. There is also a premium remote control, made from aluminium, which gives clear access to controls from the comfort of your listening position, making the amplifier easy to live with and use.  

The Nu-Vista 600.2 is an exercise in working to achieve perfection. By utilising reference-class technologies in the technically correct way, with premium component choices and proper design principles, Musical Fidelity have produced an amplifier that measures and sounds like a dream. The Nu-Vista 600.2 feels calm and smooth, never losing control of its striking dynamic range and natural, effortless transient response. Regardless of the music you are listening to, it will always deliver the best sound possible to your ears.
