The Q5s is the flagship portable DAC/Amp from FiiO and an upgrade of the Q5. As a DAC/amp, its primary function is to bypass the built-in digital-to-analog converter of your phone, laptop, or other device and amplify the signal. Its top-notch specs make it a stellar desktop DAC/amp, while its portability makes it the perfect travel companion.


As an upgrade of the Q5, the Q5s features a number of great improvements. A USB Type-C offers hassle-free connecting. A Bluetooth 5.0 chip and upgraded DAC chips provide flagship decoding--whether you plan to go wired or wireless. And a fully balanced THX AAA amp provides increased output power and lower distortion.


AK4493EQ x 2

The Q5s uses an AK4493EQ digital-to-analog converter (DAC) chip for each channel, resulting in imperceptible distortion and noise. With a total harmonic distortion plus noise rating of <0.002% and a signal-to-noise ratio (SNR) of >117dB, the Q5s plays 32bit/768kHz tracks against a pitch black sonic background. 


To put these numbers in perspective, the loudness of a jackhammer is 110dB, an ambulance 120dB. So under any normal, healthy listening scenario with the Q5s, you’re going to hear nothing but pure signal. 


Fully balanced THX AAA amp

The THX AAA lineup of amps are known for their power and clarity. Unlike many amplifiers, THX AAA amps use a feed-forward error correction topology that removes common distortion issues. To put it simply, the amp measures errors in an early part of the system and corrects them in a later part of the system. 


Additionally, the Q5s uses two THX AAA amps in a fully balanced architecture. This allows the Q5s to achieve greater output power as well as lower distortion. 


The most sophisticated Bluetooth yet

Gone are the days of downsampled Bluetooth. Thanks to Qualcomm’s QCC5124 Bluetooth chip, the Q5s supports all the hi-res bluetooth audio codecs: AAC, SBC, aptXLL, aptX HD, and LDAC. 


Ditch the charger

Depending on which input you’re using, the Q5s’ battery can last between nine and twenty-five hours--9 for USB and bluetooth, 25 for AUX. So at the very least, the Q5s can survive a flight from Boston to Seattle with time for layovers. 


Six inputs and outputs

We never said this was just a Bluetooth DAC/Amp. With inputs for optical, coax, line-in, and USB, plus outputs for line out, 3.5 single-ended, 2.5 balanced, and 4.4 balanced headphones, the Q5s is your personal middleman for a million different listening scenarios .
