FiiO’s updated Q3 amp features XMOS new flagship XMOS XU316USB chip and is capable of decoding PCM up to 32bit / 768kHz and DSD up to DSD512 natively as well as Full MQA decoder support and continues to support fully balanced THX amplifier module.

True MQA Support

MQA, Master Quality Authenticated is the latest technology where we get high-res performance in small file sizes. The updated FiiO Q3 version now supports full MQA unfolding allowing the users to listen to the true master quality performance as the artist intended while recording.

THX AAA Amplification

FiiO Q3 uses the highly reputed THX AAA Amplifier Technology. Previously used for the replaceable amplification module for the Q5s, FiiO this time they used it at the heart of their Q3. The fully balanced THX amp module has a patented feed-forward error correction topology paired with rigorous OP-Amp components. It helps the Q3 to achieve a powerful output capability. The Q3 also shows low distortion, rich bass, and an overall outstanding music experience.

High-Performance Decoding Chipset

The Q3 is equipped with the latest generation of XMOS USB signal receiver chip and high-performance AKM DAC chip, the AK4462. It is capable of decoding PCM up to 32-Bit/768kHz, and DSD up to DSD512 natively. The output with Q3 connected to a normal smartphone or PC is buttery smooth, has powerful bass, crisp detailing, and lush vocals suiting different genres of music very well.

Multiple Output Ports and Analog Potentiometer volume knob

The FiiO Q3 is catering for all your needs with its three headphone outputs. It features 4.4mm and 2.5mm fully balanced output ports as well as a 3.5mm single-ended port.

Among professional audio products, nothing adjusts volume better than an analogue potentiometer volume knob. When combined with ADC curve reconstruction, traditional problems with analogue volume knobs like low-volume channel imbalance are effectively eliminated – so that you can quickly and accurately change to your desired volume.

RGB Indicator, Gain Switches and more

The RBG indicator on the volume knob is a nice design feature and allows you to easily distinguish what sampling rates is being used. The Q3 also features a two-level gain switch, high gain and low gain, and a bass boost switch for that extra thump in the lower end.

To make the Q3 more convenient to use it has a multi-function button that allows you to quickly switch between gain levels and filters. Change your sound with some simple taps.

  •     Short press the button to switch between low/high gain (light on for high gain, lights off for low gain)
  •     Double-tap to cycle between sharp and slow roll-off filters
