Musical Fidelity Nu-Vista 600.2

After the huge success of the acclaimed and multi award winning Nu-Vista 800.2, it is time to announce the new Nu-Vista 600.2.

Compared to the old Nu-Vista 600, the updated 600.2 now features the full TITAN power amp design including locally decoupled output stage.

PCB layout has been drastically reworked and improved.

Electrical components have been updated, the 600.2 now uses the same laser trimmed volume control like the 800.2 and the PSU-section has been greatly improved.

The Nu-Vista 600.2 is their latest love letter to strictly analogue, discrete, dual mono amplifiers using big oversized toroidal transformers with multi array power supplies and the finest filtering of pre- and power section.

And on top, the beautiful Class-A tube stage consisting of highly famed, and by now almost extinct, nuvistor tubes.

The massive mechanics, stunning casework and display with VU-meters don’t only get you the best sound/ performance but also the haptical feel of true LUXURY.

Musical Fidelity believe that only a true analogue amplifier with NO DIGITAL or even WiFi streaming on board can reach the maximum of fidelity, which the concerned music lover is expecting of a Musical Fidelity product

Technical Talk

The Nu-Vista 600.2 is a much bigger update than their previous Nu-Vista 800 to 800.2 reissue.

Smaller changes include component level improvements.

The old input switching IC has been changed to relays for better separation and dynamics and only highest quality polypropylene capacitors are used throughout the signal path.

A much requested, more significant change is that the 600.2 now also uses their laser trimmed volume control for +/- 0.5dB gain error even at lower levels.

The power amp, preamp and nuvistor stage layout has been significantly revised and improved.

Preamp circuits have been removed from the back panel PCB and are now built on a self-screening tray at the top of the unit for less noise and distortion, protected from noisy PA and heavy current power supplies.

The Nu-Vista stage – now the same as in their PRE/PAS/PAM – features 6S51N nuvistors in a discrete class A amplifier buffer and is also located on the new top layer PCB.

The preamplifier, nuvistor and input circuits are now fully dual mono with separate left/right power supplies.

Continuing their pursuit for clean and proper power solutions – as they have recently shown with their new Balanced Power Conditioner range and the separate power supply units of the Nu-Vista PRE/PAS/PAM – the Nu-Vista 600.2 now features “NO SWITCH-MODE PSU AT ALL” during operation.

A SMPSU is only used in standby mode and for the amplifier this ensures best supply noise performance.

Improved digital supplies contribute to better supply rail noise figures.

The new layout comes with big performance gains and saves a lot of space.

They can now support two balanced XLR inputs to cater for both Nu-Vista Vinyl and DAC.

A balanced XLR preamp output has also been added and all line outputs are now separately buffered, resulting in no interference between devices connected to any of the preamp outputs.

The Titan Heritage

Certainly, one of the biggest changes is that we have now fully incorporated their famed TITAN design in the Nu-Vista 600.2, bringing it up-to-par with its bigger 800.2 sibling and the esteemed PRE/PAS/PAM range.

Giving each output device (transistor) a corresponding high current bulk supply capacitor allows more immediate access to stored energy, with much lower impedance path to flow through.

This results in better transient response and coincidently provides a degree of improved ripple filtering at higher currents in conjunction with the supply capacitors situated elsewhere.

The main supply capacitors are situated right on the rectifiers, also decreasing supply impedance and helping to keep rectification and hum noise away from the high gain PA circuit.

Heroic Build Quality

The Nu-Vista 600.2‘s mechanical construction is uncompromisingly rigid and solid in typical Musical Fidelity tradition.

Front panel and side panels are milled from extruded aluminium profiles and are extremely massive.

The Nu-Vista 600.2 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 HiFi gear against elec tromagnetic fields generated by the Nu-Vista 600.2.

The new Nu-Vista 600.2 is a continued labour of love for Musical Fidelity.

Their passion for Nuvistor tubes didn‘t stop.

Everyone at Musical Fidelity hopes that you derive as much pleasure listening to the Nu-Vista 600.2 as we had creating it.

Nuvistor tubes

Nuvistor tubes were invented in the 1950s to solve the many shortcomings of conventional tubes.

Unlike them, Nuvistor tubes offer very high reliability, low microphony, low noise, consistency from batch to batch, small size, relatively low power consumption and great technical performance.

One famous application was in the Ampex MR-70, a costly studio tape recorder whose entire electronics section was based on nuvistors.

Another limited application of this very small tube was in studio-grade microphones from that era, the AKG/Norelco C12a, which employed the 7586, being a good example.
