Music listening, enjoyable and practical.
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.

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
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
Compared to the USD $2000 flagship HiFi player, it is not inferior
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
