QULOOS QLS MC01/MC01se Portable USB DAC/AMP Dual Flagship CS43131 HiFi Decoder Headphone Amplifier

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.
