• The so-called “pursuit of details in small size”: In spite of small size, high-density and thick sound can also be offered
• 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.
• 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.
• 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.
