|
| How to choose the versions |
 |
● MC01 for balanced port earphones.
● MC01se for single-end earphones.
● For both balanced and single-end earphones.
1.MC01 can be achievable in most cases.
2. Both MC01 and MC01se are recommended for users who are
used to single-end, and have rich listening experience.
|
 |
|
| Design idea |
● MC01 provides both 3.5mm single-end and 4.4mm balanced
headphone outputs. It utilizes only half of the dual
decoding chips for the 3.5mm single-end output.
● The balanced port of MC01se has been cancelled. With the
parallel output of two DACs, the 3.5mm single-ended output
can be served by both DAC in four ways. Also without the
balanced output, there is more room to optimize the
single-ended sounds.
● To make the single-ended sounds convey a higher sense of
depth and stereo perception, the gain of MC01se headphone
amplifier has been triply increased. However, signal
amplification will simultaneously increase distortion and
noise, so the test parameters showed a bit poor.
|
|
 |
|
| Style of sounds |
● The previous prototype is similar to QA361 regarding the
style of sound, focusing on a sense of depth,
the transparency and clarity of sounds.
●The apparatus finally put into mass production enhanced the
atmosphere with higher sound density. Sound tends to be
relaxing and generous like those of QA360LE based on the
sound tunings of QA361. But in terms of imaging, it’s a bit
like those good-quality magnetic tape devices in early days
and conveys a sense of heaviness and solidity.
|
|
 |
|
| Power supply is the origin of sound |
| Three power filters optional |
● In order to secure pleasant sounds provided by MC01 with
all of the devices equipped, a triple LDO (with triple power
filtering settings) is optional on the menu designed for the
power supply on key position. Theoretically, it can achieve
a high PSRR, up to hundreds of dB.
● Low-noise LDO chips, such as LT3042 and ADM7170.
|
|
 |
|
| Clock is the essence of sound |
| A good crystal oscillator produces a stable sound |
In order to produce a more accurate sound, the audio crystal
oscillator of MC01 has been selected among dozens of
models/brands. Finally, the high-precision femtosecond
crystal oscillator with only 150fs of nominal jitter has
been used.
|
|
 |
Measurement based on the audio analyzer APX555 |
|
| The adjustment of sound style is the basis of sounds |
| The final sound effect depends on the adjustment of tunings |
After the sound tunings determined, most of the electronic
components used inside have been reselected based on
performance and sound, to confirm the brand, model and
parameter.
|
|
 |
|
| Compatible with multiple devices |
MC01 supports Android smartphone and
PC, iPhone and Ipad, computers installed with Mac or
Windows, Switch and many other Hi-Fi music players with USB
OTG outputs.
|
|
 |
|
| Dual flagship DAC chips |
| MC01 has lower distortion than the theoretical value DAC given |
With two flagship CS43131 chips, MC01 provides better sound quality.

|
| Flagship dynamics |
With the background noise reduced to as low as 1.2uVrms at the balanced output and the SNR up to 131dB, the background noise can hardly be heard even if it’s connected to any earphone with high sensitive.

| Game experience |
| Precise sound localization plays a vital roles when playing |
In games, except for the
experience of images and high-speed, sounds also play a
very important role. It will bring such a game
experience that sounds are in sync with pictures and the
footsteps.
