Instructions for use
Thank you for purchasing the Nu-Vista DAC by Musical Fidelity. Based on our excellent nuvistor tube
technology, we decided to go all out “fully balanced” on the Nu-Vista range.
The Nu-Vista DAC is our new flagship DAC built around the critically acclaimed ESS 32-bit HyperStream II
DAC architecture. It features RCA and XLR outputs, 3x optical and 1x coax SPDIF inputs, 1x USB and 1x
AES/EBU inputs. A I2S input is also there, for a future yet to be announced Nu-Vista CD-player!
Building on our knowledge and experience with Sabre ESS chips, the Nu-Vista DAC uses 2x ES9038Q2M
chips in dual differential mode for a pristine dual mono design. The inclusion of a Time Domain Jitter Eliminator
results in superb SNRand THD+N performance with unbelievably detailed transient response. Other advances
in the DAC section include optional upsampling and re-clocking and an oversampling bypass mode. The 16-
core XMOS and CPLD MAX II Altera processors ensure there is always enough headroom for these
operations, the digital filters, including our own new proprietary filter for optimum transient response, and the
MQA processing.
Optionally, the Nu-Vista DAC can be powered by the Nu-Vista Uni PSU (set to be released in 2024). This will
achieve better noise performance, by moving the AC mains power supply from the main unit and build it into
another matching box. We are taking advantage of the extra space to set up mains and output filtering a step
above what is usually possible in one-box-solutions.
Also included is the Nu-Vista remote control which is a solid “Nu-Vista” style re-imagination of usual remote
controls. Machined from solid, it has the same feel as the front panel of the unit, has a powerful beam, and
runs off easily replaceable AAA batteries.
Used properly and carefully, it should give many yearsof outstanding musical reproduction. Dust regularly with
a soft duster or soft brush, but be careful when using cleaning or polishing agents - they may harm the surface
finish.
If there are any questions about the audio system, please consult the dealer, who is there to help and advise.
