Q3 MQA Portable DAC and Amplifier

All-new XMOS XU316 chip | Efficient AK4452 DAC THX AAA-28x2 amps | Fully supports MQA decoding Dual power supply design | ADC volume adjustment All-new strapping kit | RGB indicator | Two gain levels

Inside and out, absolute brilliance

The Q3 MQA Edition is equipped with the next-generation XMOS XU316 controller chip, among the latest for use in USB DACs. The XU316 features 16 cores made in an advanced manufacturing process, bringing high-performance processing and allowing support up to PCM 384kHz/32 bit and DSD256 high-resolution audio formats.

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 to 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.

Extraordinary sound, THX AAA-28x2 amplifiers

Featured in the Q3 MQA Edition are two THX AAA-28 amplifiers, allowing for a max power output of 330mW (370mW when using Line in mode). Experience hugely powerful, extraordinary sound.

At the audio forefront Fully supports MQA decoding

Thanks to the powerful XMOS XU316, the Q3 now fully supports decoding the MQA format, allowing you to unfold and render any MQA folder when using a player that supports MQA.

Vivid life Dual power supply design

Comfortably use the Q3 MQA Edition in any scenario, whether as a portable device or a static device on your desk. Quickly switch between how the Q3 MQA Edition is being supplied power using the Charge switch on the bottom. Using AUX in the battery life is up to 23+ hours, and when using USB in the battery life is up to 12+ hours.

Experience upgraded All-new strapping kit design

The all-new strapping kit designed to bundle together the Q3 MQA Edition to your phone greatly improves upon the experience from before. The innovative X-shaped straps no longer block the display of your phone, and the intermediate films protect your device and prevent the Q3 MQA Edition and your phone from being misaligned when strapped together.

Colorfully cool RGB indicator light

The RGB indicator light is not only striking, but also instantly lets you know the current audio track’s specs and sampling rate.

Blue: PCM
Green: DSD
Magenta: MQA

Smooth experience Thanks to ADC volume adjustment

The ADC curve reconstruction method for adjusting volume not only effectively solves the problems of channel imbalance and noise, it also greatly improves the accuracy when adjusting the volume. Relish in making the volume just right for you.

Feel richness of music
Two gain levels & BASS boost

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. 

Listen the way you want
Numerous audio outputs

Listen to your music the way you want through either the 3.5mm single-ended output or through the 2.5/4.4mm balanced outputs.
