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.

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.

Design goals, favorable parameters and better sound!

Try to be irreplaceable in terms of audio impression (And this is the key of product value)

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.
