Listening impressions from Clark:
MUB1’s general
sound design is consistent with QA361 and QA390LE. With
high sound density and a strong sense of structure, this
music is warm, sensitive, steady, and long-lasting to
listen to. It has excellent hierarchical details and
vertical spatial feeling.
The PCB area and power supply of MUB1’s DAC&headphone
amplifier section are greater than those of QA361 since
it lacks a player part. MUB1 is an inch long and an inch
strong, and it has a few advantages over QA361 in terms
of sound quality. These advantages include a larger
sound field, a more complete sound structure, a sound
that is softer and more durable to listen to, greater
sound dynamics, and more solid mid- to low-frequency
reproduction.
How could such lovely and sweet music not make you feel
something? Therefore, I believe that each enthusiast
needs at least one MUB1.

|
|
 |
|
Three keys to good sound in MUB1 |
|
| |
|
2.75
times the power of QA361 dual high mode |
|
|
|
Sufficient power margin
The sound is more easy and adaptable
MUB1 balance port output power up to 1100mW/ch
It is much greater than the output power of many
flagship players
Put fine timber to petty use
|
|
 |
| |
|
Super-Hign gain is 3-4 times voltage amplification with high gain |
|
|
|
|
Modern machines pursue testing parameters
The sound gets more flat and ordinary as the gain drops
MUB1 returns to traditional old machines with over 10 times
voltage amplification
Outstanding musical taste causes listeners to unconsciously
dance to the music
Realistic visuals set to vibrant, exuberant music that seems
just out of reach |
|
 |
| |
|
HiFi performance needs to be ensured by the materials used |
|
|
|
Use desktop HiFi materials
Make MUB1 sound more like a real HiFi device
Audio electrolytic capacitors are rarely used in portable
goods.
Panasonic electrolytic capacitor with rare sound dense sense
of space
The BUF634 provides a more scaled sound
Low internal resistance Wurth inductor with stable and
atmospheric sound |
|
 |
| |
|
Sound created by power supply |
|
|
|
Design of a power supply that is
broadband, low noise, high transient, and low in internal
resistance
Up to 14 power sources provide independent power supply for
each circuit part, ensuring purity and stability
This battery cable is combination of HiFi wires using
different materials, resulting in a noble sound.
Analog power supply voltage of up to 16V at Super-high gain,
with sound more open.

|
|
CAR mode that simplifies car audio upgrades |
|
|
|
MUB1 has optical and coaxial outputs, and
Line out can also be set
One line connection to the car audio DSP is sufficient,
simple and convenient
Connect to the host Aux in through level setting Aux out
Both Apple and Android phones can increase the volume on the
phones, making it more convenient
In CAR mode, following USB power to automatically switch on
and off, more worry free |

Four Cirrus Logic flagship DAC chips |
|
|
|
Start liking Cirrus Logic DAC due to the
good sound quality of CS4398
It has the uncommon natural, enjoyable, and smooth sound of
a contemporary DAC
The new generation CS43198 and 43131 have better designs
The sound is more precise and realistic thanks to the
special NOS option.
Using 4 CS43131, eight channel DAC designed as two channels
Each four channel DAC is for providing more detailed and
louder sound |
|
 |
|
MUB1 overall distortion is better than the
theoretical value of DAC chips |
|
|
Flagship level dynamics |
|
|
|
Compared to the USD $2000 flagship HiFi
player, it is not inferior |
|
 |
|
Measurement based on APX555 audio analyzer |
|
|
|
Almost “zero” noise |
|
|
|
MUB1, whether single ended or balanced,
the medium and low gain noise <2uVrms
50% of 4uVrms noise at low gain only for QA361
The signal-to-noise ratio is as high as 132dB
High sensitivity headphones also struggle to hear background
noise |
