Q3 MQA

The HiFi world is growing with diversities. From portable and compact Bluetooth earphones to portable Bluetooth DAC/Amplifier, lossless music player and then to desktop DAC/Amplifier, neither of them would sacrifice excellent sound quality as well as much fun of enjoying music in different scenarios. Among which, FiiO Q1 MarkII was a portable DAC/Amp sweetie that has been terribly adored by audiophiles since a long time ago. Coming with Hi-Res sound performance in a perfect-controlled body, not only can the Q1 MarkII satisfy your needs on multiple-use scenarios, but also it got set all the time to improve music performance for your devices. It has been 3 years since the Q1 MarkII came to the world. However, we will not continue to commemorate it here. Today we are going to introduce a new DAC/Amp friend for you- the THX Balanced DAC/Amplifier, FiiO Q3.
