MUSICAL FIDELITY Nu-Vista DAC Speaker Shack
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 SNR
and THD+N performance with the 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 building 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, 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
years of 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.

GENERAL ADVICE
Installation, Precautions & User Information
This new Nu-Vista DAC is designed and built to provide trouble-free
performance, but as with all electronic devices it is necessary to observe a
few precautions:
- Heed all warnings shown on the back of the product.
- Only connect the Nu-Vista DAC to a mains outlet having the same voltage as marked at the back of the unit.
- Always ensure that when disconnecting and reconnecting your audio equipment the mains supply is switched off.
- Position the mains lead and signal interconnects where they are not likely to be walked on or trapped by items placed on them.
- Do not use near water, or place water-filled containers on the Nu-Vista DAC, for example, a flower vase or potted plants. If water does spill inside, immediately pull out the mains plug from the wall socket and inform your dealer, who should then check the unit before further use. Entry of liquid into the Nu-Vista DAC is dangerous and may cause electric shock or fire hazards.
- Do not place the unit near direct heat sources such as radiators, direct sunlight or other equipment.
- Do not remove any covers or try to gain access to the inside. There are no internal adjustments or fuses you can replace yourself. Refer all service work to an authorized Musical Fidelity agent.
- Note : Unauthorised opening of the equipment will invalidate any warranty claim.
- Dust regularly with a soft cloth or soft brush but be careful when using cleaning or polishing agents – they may harm the surface finish.
The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected or damaged by lightning. For the protection of the audio system during electrical storms, remove the main plugs. If after-sales service is required, to help the dealer identify the Nu-Vista DAC please quote the serial number located on the rear panel of the unit.
INSTALLATION
introduction
Congratulations on the purchase of the new Nu-Vista DAC. Great attention has been paid to internal layout, isolating each circuit section to prevent possible interaction. The unit features a finely tuned and tweaked Nu-Vista valve design, for smooth sound coupled with low noise and virtually no distortion. This unit will deliver the ultimate performance possible from any digital source. It is designed to upgrade CD players, TVs, set-top-boxes, DAB tuners, USB Streamers PCs Laptops, and any other source providing a variety of digital outputs.
Cleaning
Before cleaning the unit, switch off the power at the mains switch and remove the mains plug from the wall socket. Clean the cabinets using a moist cloth. Using solvents, white spirits, or thinners is not advised, as they could damage the surface finish.
Setting up
Position the Nu-Vista DAC on a stable, horizontal surface where there is no risk of it being knocked. Make sure ALL units involved are switched off and unplugged from the main supply before making or removing any connections.
ower Connections
The Nu-Vista DAC is supplied with a standard IEC mains cable which plugs into the IEC socket at the back of the unit. Upgrade power connection: Optionally, the Nu-Vista DAC can be powered by the Nu-Vista Uni PSU (set to be released in 2024) via the PSU RH Power, LH Power, and Control connections. Please refer to the Nu-Vista Uni PSU manual for details.
Audio Connections
- Outputs: The Nu-Vista DAC has a single-ended RCA line level and a balanced XLR line level output. Both can be used simultaneously.
- RCA audio output : Use good quality RCA phono audio cables (fully connected signal and ground), for optimum signal transfer.
- XLR audio output: Use good quality XLR audio cables (fully connected hot and cold signals and ground), for absolute optimum signal transfer.
Digital Input Connections
- COAXIAL input: Connect RCA digital source to digital input RCA socket. Use a good quality fully connected (signal and ground) coaxial digital cable, for optimum signal transfer.
- OPTICAL inputs: Connect the optical digital source to the optical input socket. Use a good quality “Toslink” cable, for optimum signal transfer.
- USB input : Connect a computer or similar USB “host” source to the USB input socket. Use a good quality USB 2.0 type cable (not supplied), for optimum signal transfer. Try to keep the USB cable length to a minimum for best reliability. The USB standard maximum for a single cable is 5M, after which repeaters (normally mains-powered USB hubs) are required. We do, however; recommend avoiding such a setup if at all possible.
- AES/EBU input: Connect a balanced AES/EBU source to digital input XLR socket. Use a good quality XLR cable, specifically designed to carry digital signals and not XLR cables for analogue audio transmission!
- I2S input : Use a good quality HDMI cable to connect the upcoming (released in 2024) Nu-Vista CD.
Trigger Input and Output
Triggering input and outputs are available to allow the DAC to be turned on automatically by other equipment or turn on other equipment automatically when the Nu-Vista DAC is turned on. This is a 2-way 3.5mm jack on the back of the unit labelled “TRIGGER”. It requires 5 to 12V (either polarity) to switch the DAC on.
Mounting optional Spike Feet
The Nu-Vista DAC can optionally be used with spike feet. We recommend asking a second person to help you lift the Nu-Vista DAC for mounting the feet or felt pads. If you want to use the standard mounted feet, you can attach the big felt pads to those feet (remove the small rubber feet first if necessary). To mount the spike feet, screw the threaded rods into the spike feet so that the Allen key side is inside the foot (this way, when you want to remove the foot from the amplifier again, you can unscrew the foot and then unscrew the threaded rod from the amplifier with an Allen key, should it be too tight to unscrew by hand). Then screw the feet into the amplifier (remove the small rubber feet first if necessary). Attach the small felt pads to the bottom of the spike feet cups and place these cups under the spike feet.

The universal remote control shown below enables functions from this and related units to be operated from a convenient distance. Equivalent buttons on the remote control have the same functions as those on the front panel of the unit. Other functions are only available by remote control. As the handset uses an invisible infrared light beam, the front edge must be pointed directly towards the receiver window at the front of the player, without visual obstruction between them. If the range of the remote control greatly decreases, replace the batteries with new ones. Do not mix old and new batteries – two are required, size AAA, LR03 or SUM-4.
Please dispose of used batteries in accordance to local regulations
starting
Once the Nu-Vista DAC unit is correctly wired up, and plugged into mains, the Standby LED will light up. In this mode, the Nu-Vista DAC is consuming a minimal amount of power. To switch the unit on, press the Power button (4) on the front of the unit or the remote control. The display will now light up and the POWER LED will light up. The LEDs illuminating the Nuvistor valves will light up RED. This means the outputs are muted, and will remain in this state for about 12 seconds, so no sound will be heard. Once the delay is up, these LEDs go ORANGE, indicating the unit is ready for use, and any source material selected and playing will be heard. For the first 15 mins or so, the Nu-Vista valves are still warming up, and their LEDs stay ORANGE. After approx. 20 mins the valves will have reached full thermal equilibrium and are at their best performance, which is indicated by their LEDs turning BLUE.
Input selection
The Nu-Vista DAC has a total of seven inputs available. These are Optical 1, 2, and 3, Coaxial, AES/EBU, USB and also I2S (I2S is reserved for a later to- be-released Nu-Vista CD player). After a Factory Reset the USB input is selected and the volume is set to -42dB. When the Nu-Vista DAC is taken out of sleep mode, it will default to the last input selected. From the front panel, you can cycle through the inputs by using the input selector wheel 1. The remote control has direct access buttons for each input. Simply press the appropriate button to move directly to that input.
Optical, coaxial & AES/EBU inputs
These are capable of accepting up to 24-bit 192 kHz PCM stereo, MQA 384kHz,
and DoP DSD 64 data streams. The incoming data sample rate is displayed on the
front panel display for reference.
USB Input
The USB input is capable of accepting up to 24 bit 768 kHz PCM, DSD 256 (native DSD 512) data streams and all MQA data streams.
Computer settings for USB
A good quality USB 2.0 cable is required to connect the unit to the computer. Normal USB standards stipulate that this should be 5M or less; and we recommend keeping it as short as possible.
WARNING: Older USB cables are often heavy and bulky and must be supported to avoid damage to the USB socket. Any physical damage caused to this socket will not be covered by warranty. The computer should now detect the Nu-Vista DAC. A driver installation is only required on Windows
- Linux kernel 2.6.33 or later (no driver required)
- Apple OS X® 10.6.4 or later (no driver required)
- Windows 10 Creators Edition or later (driver found on included CD or on Musical Fidelity website)
For playing native DSD on Windows a driver installation is required. Any
device that is compliant to the USB Audio Class 2.0 standard should also
operate with the Nu-Vista DAC. However Musical Fidelity are unable to provide
support for operation with anything other than the system listed above. CD,
MP3, WAV, AAC/+, OGG, FLAC, and any other audio file types played on suitable
playback software will now play through the unit.
Note: This USB input has a high-speed serial data processor, and by its
nature, requires a very high volume of USB bandwidth. It will benefit greatly
from being the only device connected on its USB ‘bus’. Sharing the same bus
with other devices could cause unwanted artefacts such as dropouts or
temporary loss of signal. This especially includes the use of the unit on a
USB hub/splitter whether alongside other USB components or not. A direct
connection to the host computer by the shortest USB 2.0 lead possible is very
much recommended
Menu Navigation
Enter the menu by pressing Enter 6 or the up/down/right arrow button on the
remote. Use the Back 5 and Enter 6 buttons to enter sub-menus or go a step
back. On the remote this is done with the left and right arrow buttons.
Confirm your setting with the Enter 6 button or the OK button on the remote.
After 10 seconds of inactivity, the screen switches back to the main view.
Nuvistor LED Indicator Line
Indicates that the device’s Nuvistor tube LEDs are on. The blue LEDs can be turned on and off by holding the Back 5 button for 2 seconds. If the blue LED’s are turned off, the blue top line is not displayed either.

- OFS – Original Frequency Spectrum (with magenta dot) – 44,1k/48k/88,2k/96k/176,4k/192k/352,8k/384kHz
- MQA Studio (with blue dot) – 44,1k/48k/88,2k/96k/176,4k/192k/352,8k/384kHz
- MQA (with green dot) – 44,1k/48k/88,2k/96k/176,4k/192k/352,8k/384kHz
MQA (Master Quality Authenticated)
- The Nu-Vista DAC includes MQA technology which enables you to play MQA audio files and deliver the sound of the original master recording. Visit mqa.co.uk for more information. MQA Indicators:
- MQA – Green dot – indicates that the product is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material.
- MQA Studio – Blue dot – indicates it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.
- OFS – Magenta dot – (Original Frequency Spectrum) confirms that the product is receiving an MQA stream or file which is already decoded. This delivers the final unfolding of the MQA file delivered by services like TIDAL or media players like Roon.
Sample Rate
the sample rate of the incoming audio signal.
Digital Oversampling FIR Filter
Displays the currently set digital oversampling FIR filter. Choose your
digital filter in the Audio Settings -> Digital Filters sub-menu or by
pressing the FILTER UP and FILTER DOWN buttons on the remote. For a detailed
description of each filter see page 14.
Note:
When playing MQA files, the user’s filter setting is not active, the MQA
filter is always used. The MQA filter is a proprietary custom-made filter by
MQA for our DAC to ensure the best possible MQA experience.
DSD filter: During DSD playback, the DAC’s internal DSD filter is turned on
and the digital filters have no effect.
Oversampling bypass
for sample rates of 705,6k and 768kHz the oversampling FIR filters cannot be set and are automatically bypassed. The unit goes into oversampling bypass mode. At these high sample rates (native sample rates of the DAC) the digital signal goes directly into the DAC without filtering. Effectively, this turns off all remaining filtering, improving audio parameters and the frequency spectrum by yet another step. In this mode, the internal oversampling filter block of the ESS DAC chip can be bypassed and powered down, reducing the on- chip PSU / ground noise and consequently reducing signal-correlated clock modulation on the ESS DAC’s silicon die. The oversampling filter is the largest single digital section “block” on the DAC by silicon area.
- Upsampling is automatically disabled for 705,6k and 768kHz sample rates.
Input
- Displays the currently used input.
Volume
Displays the current volume level. Volume can be set with the Volume Wheel 3
or the VOL DOWN and VOL UP buttons on the remote. Levels from -90dB to 0dB in
1dB volume steps are possible. The MUTE button on the remote mutes and unmutes
the unit. If mute is active, a corresponding icon is shown in place of the
volume display.
The outputs can be set to fixed output (no volume control) by disabling the
volume control in the menu screens under Audio Settings -> Volume Control.
Fixed mode (Volume Control DISABLED) is suitable for connection to other
equipment which offers a volume control. Variable mode (Volume Control
ENABLED) allows connection directly to power amplifiers or active speakers
where the Nu-Vista DAC provides the volume control.
Reclocking
Reclocking synchronizes digital audio signals with the master clock in the Nu- Vista DAC. Reclocking can be turned on and off in the menu screens under Audio Settings -> Reclocking or by pressing the RECLK button on the remote. If reclocking is active, a corresponding icon is shown.
Upsampling
For incoming PCM signals, upsampling can be turned on or off in the menu screens under Audio Settings -> Upsampling or by pressing the UPSAMP button on the remote. When turned on, incoming PCM data up to
192kHz sample rate is resampled to the sampling frequency of 352,8kHz or
384kHz according to the original multiple of the sampling frequency. If
upsampling is active, a corresponding icon is shown.
Note : Upsampling is automatically turned off for 705,6k and 768kHz
sample rates.
Bit Depth
Displays the bit depth of the incoming audio signal:
- 1 bit – only used for DSD
- 16-bit – used for PCM, MQA, OFS
- 24-bit – used for PCM, MQA, OFS
System settings
Theme: using the menu screens under System Settings -> Theme you can set the
display to dark or light mode.
Brightness: using the menu screens under System Settings -> Brightness you can
set the display brightness level. Setting the brightness to the lowest level
turns the display off. When the unit is controlled, the display is briefly
turned on and switches back off after 3 seconds of inactivity.
Factory Reset: using the menu screens under System Settings -> Factory
reset you can perform a factory reset. This resets all settings (audio
settings and system settings) to factory default values.
About: using the menu screens under System Settings -> About you can view
legal and firmware information.
Digital Filters
The Nu-Vista DAC allows for detailed tuning of the audio experience. It comes
with multiple preset reconstruction filters built-in. Musical purists can
simply unpack the Nu-Vista DAC, carefully cable it up, just leave it at its
standard settings and feel the immediate musical integration: the whole sound
is sweet and clear; the treble is completely grain-free and extended. The
bottom end sounds endless with tactile bass dynamics.
As you get reintroduced to your music library, you might, at some point, want
to discover what else is possible and hear it from different stages. It is
then that the customizability and settings turn the Nu-Vista DAC into a
powerful tool for experts, which elevates it into a league of its own. Explore
the sound stage with upsampling and reclocking or without and see if you are
drawn in deeper.
Choose between the different digital filters and tailor the sound reproduction
to your specific liking or to your specific setup. In a way, the Nu-Vista DAC
can be used like a professional tool for the experienced user:
- Linear Phase Fast: fast roll off – Most common filter with clean overall suppression and excellent rejection, best for music with large transients. Provides crisp clean highs.
- Linear Phase Slow : slow roll-off – Low group delay – and symmetrical input response. Less ringing than linear-phase fast roll-off. Punchier bass than LPFR, with clean highs.
- Minimum Phase Fast: fast roll off – Minimal pre-ringing, preferred for imaging and soundstage. No aliasing in the frequency domain. Stronger bass than linear-phase, clean highs.
- Minimum Phase Slow: slow roll-off – Non-symmetrical filter designed to minimize pre-ringing. Strong punchy bass with good transient attacks.
- Apodizing Fast Filter : fast roll-off – A version of the linear-phase fast roll-off filter optimized to improve pre-ringing.
- Corrected Phase Fast: fast roll off – A combination of linear phase and minimum phase. Fast transient attack, strong punchy bass, crisp highs.
- Brick Wall Filter: One of the earliest designs, intended for the highest suppression possible, with high delay and pre-ringing. Linear-phase, crisp clean highs.
- Optimal Transient: Our proprietary custom filter. In this filter we trade off frequency domain performance for optimum time domain performance resulting in a slight frequency roll-off at 20kHz, but zero pre-ringing and zero post-ringing.
Troubleshooting
| Problem | Probable Cause | Remedy |
|---|---|---|
| No power. | The power plug is not inserted into the socket correctly. | Plug in |
securely into the unit’s IEC socket.
Excessive hum from system speakers.| The audio connector plug is not fully
pushed in. Cable Fault. Unsuitable Cable (e.g. cable grounds not connected).|
Insert plug securely. Check cable is connected at both ends. Some “esoteric”
cables have internal wiring intentionally disconnected/modified. For best
results on all inputs, please use a good quality screened coax; signal and
screen directly
connected to both ends.
Digital input not working.| No connection to that input. Incorrect input selected.
The wrong data type was sent to DAC.
| Check connection and cable. Select the correct input. Check source digital output is set for “16 bit stereo PCM” or similar. This particularly applies to some TVs, most DVD players, and other home theatre-type devices that may give a multichannel digital
output. Refer to the source’s manual for further information.
No audio output, or too low-level output.| Incorrect or missing connections. USB Driver not selected.| Check connections and make sure they are secure. See the
Musical Fidelity website for relevant OS setup information.
Dropouts in sound.| Digital input leads not properly connected. Faulty digital
input lead. Faulty optical lead.| Check input lead is fully secured. Change
lead. Please use a good quality straight-through signal-and-ground phono to
phono lead. Optical lead breakage. This can occur if the optical lead is bent
into a radius too small. Avoid tight corners in routing optical leads.
No audio output from USB input.| USB Cable is not connected. M6 USB Driver not
selected.| Check connections and make sure they are secure. See the software
section for relevant OS setup information.
Please check device is listed in the device manager (Windows®) or in Sound, and audio devices for MAC OS X.
Make sure the Musical Fidelity USB audio device is selected as the default OUTPUT device.
Check USB port functions with another device.
Not detected when connected to USB.| USB Cable is faulty. USB not working/ enabled on the computer. Correct USB drivers are not installed.| Check and replace the cable.
Check USB port functions with another device. Download and install the device driver from the software downloads section on the Musical Fidelity website.
Dropouts in sound (USB input).| Shared USB port with another device.
The computer busy with another application. Computer low on resources.
| Avoid sharing the USB port with other devices, if possible. At times an application (program) may intervene, sometimes invisibly e.g. a virus scanner. When this happens, computer
resources are temporarily used up, and playback may suffer.
This is not a fault. Try running fewer applications if possible.
- If none of these actions affect a cure, please contact the dealer or an authorized Musical Fidelity service agent. Remember; never open the case of the Nu-Vista DAC, as this will invalidate the warranty.
