Musical Fidelity’s new flagship in digital audio processors, the Nu-Vista DAC is a spectacular electronics built around the renowned D/A conversion scheme with 32-bit technology ESS Technology HyperStream. To this we must add, as its name indicates, the famous tube circuitry Nuvistor of the Musical Fidelity brand, materialized in the presence of a completely balanced stage of Nuvistor 7586 triodes on each channel, integrated into a buffer amplifier configured in Class A and executed entirely with discrete components. Specifying the digital section in a little detail, two “chips” ES9038Q2M in dual differential mode for a pristine dual mono design, allowing the Nu-Vista DAC to support PCM files with maximum sampling rate of 768 kHz, DSD up to DSD256 via DoP, native DSD up to DSD512 via USB and MQA up to 384 kHz, which for practical purposes implies the full compatibility with any musical content whether from a download or played via streaming.
Likewise, there is a extremely quiet and precise regulator Designed specifically for high-performance audio systems and optimized for “Hi-Res” sound, thanks to its revolutionary dual architecture. For its part, the inclusion of a “jitter” elimination scheme in the time domain (“Time Domain Jitter Eliminator“) results in some rspectacular records in the signal-to-noise ratio and total harmonic distortion, which are complemented by a transient response incredibly detailed. The critical synchronism clock contributes to this, in which a meticulously careful design has made it possible to place the jitter level below 100 femtoseconds. Of the DAC section of Musical Fidelity’s new digital “superprocessor”, it is also worth noting the optional possibility resampling and resynchronizing the signal, as well as avoiding oversampling and executing digital filtering and MQA processing, all of which are entrusted to powerful processors 16-core from the American firm Altera.
As far as the analog part of the Nu-Vista DAC is concerned, the first aspect to point out is without a doubt the aforementioned use of Nuvistor valvesunique in the audio industry and that, in combination with a opulent block power supply featuring one of the exclusive toroidal transformers “Super Silent”empowers Musical Fidelity to offer a fabulously silky and dynamic sound. As befits a product of its category, this superb electronics is completed with a generous connectivity, featuring balanced and unbalanced analog outputs and coaxial (1), optical (3), USB (1) digital inputs; AES/EBU (1) and even I2S. Approved Roon Tested and featuring an extraordinarily robust mechanical construction, the Nu-Vista will soon be further enhanced with the addition of the optional Nu-Vista Uni-PSU external power supply.
