Product Launch: Fiio Q3 Affordable THX AAA DAC/AMP!


We’re all likely familiar with Fiio by now. The company has achieved unanimous recognition around the globe for their products that balance features and affordability. The value offered by their source devices, in particular, was reinforced when they adopted THX’s AAA amplifier circuits that boosted efficiency and measurable performance. The Q3 is their latest portable DAC/AMP featuring this innovation. Design-wise, it clearly takes a page out of the Q1 MKII’s book with a similar albeit elongated housing.

At its heart lies an AKM AK4462 DAC chip and XMOS XUF208 usb-decoder that enables file support up to 32-bit, 768kHz alongside DSD512. With an efficient THX amp chip, the Q3 offers a whopping 19hrs of runtime. It also features a flexible 3 outputs up from the Q1 MKII’s dual outputs – with 3.5mm, 2.5mm balanced and 4.4mm balanced too. The effective pure hardware bass-boost makes a return too for those wanting a punchier listening experience.

The Q3 comes in at a reasonable $150 USD and looks to be very fully-featured considering. You can read all about the Q3 and secure pre-order for yourself on Apos Audio. Specs below:
