Meticulously tuned, classic relaxed sound

Due to the disrupted supply of AKM DAC chips, the Q3 MQA employs the AKM AK4452. Through numerous adjustments, this chip was tuned so that its performance is similar of that of the DAC in the original Q3 and with even slightly improved power output. The Q3 MQA still features the same charming sound that made the original Q3 so beloved.

RGB indicator light

The gain and BASS boost buttons allow you to tailor the sound to different styles and to your liking, letting you better appreciate the richness of music.

The BASS boost is achieved in hardware, allowing a bass boost up to 6dB without affecting the higher frequencies.
