FiiO Q5 Flagship DAC/Amp with Dual DAC, USB/Optical/Coaxial/Line in

The Q5 is FiiO's current flagship DAC, a powerful, Hi-Res amplifier with a range of connectivity options


The Q5 uses an all aluminium alloy chassis to effectively resist electromagnetic interference. The rear of the Q5 features a PU leather casing, which is scratch-resistant for stacking use.

An analog-to-digital (ADC) volume adjustment knob allows for no problems in volume imbalance, greatly enhancing accuracy with 256 different levels of volume adjustment. This is achieved by taking the incoming analog sound signal, converting it into digital for sampling and volume adjustment, then reconstructing the volume curve on the other side.

With the side buttons, users can operate play/pause functions and skip through tracks with ease when connected via Bluetooth.

To customise your sound further, the Q5 features an interchangeable amp module design, fully compatible with the X7/X7ii DAP modules.

Hardware Configuration

The Q5 uses dual AK4490EN DACs capable of decoding up to 384kHz/24bit, with an extremely low SNR. There is an official Apple MFi certified chip, meaning the Q5 supports digital decoding to iOS devices without worrying about software updates. The Bluetooth chip supports aptX, and there are 7 LDO voltage regulators that each provide independent power supply via a power management filter, ensuring a clean power supply and low interference to get a purer sound quality.

The 3800mAh rechargeable lithium battery allows for 10 hours of USB use, 10.5 hours of coaxial use, 14 hours of auxiliary use, and 10 hours of Bluetooth use.


The Q5 has a USB DAC mode that supports decoding up to 384k/32bit and DSD256. There are dual micro USB ports. By default, the one to the left is for charging while the one at the bottom is for data input. There is a 3 in 1 composite output port for aux/coax/optical connections. There are both single ended and balanced headphone outputs on the supplied AM3A amp module. For different listening requirements, the Q5 features gain/bass boost.

Despite the wide range of compatible input methods, the Q5 can automatically detect which is being used, and the light on the device changes to a corresponding colour indicating the input currently in use.

To help save battery, if the device detects no input signal, it will turn off automatically after a certain period of time (default: 10 mins). When connected to a smart phone or computer, the Q5 will not draw power from the source device.

    Avrebbe senso abbinarlo alla dock k5? Se do in ingresso alla K5 il segnale da PC o palmare, verrebbe convertito dal Q5 e preamplificato sull\'uscita linea dal K5? Grazie

      Tutto sommato no, il K5 non contiene un DAC, ma solo un amplificatore per cuffie, e poi fa da Dock per lettori FiiO ( ma non per il Q5).

    Salve, volevo chiedere se il modulo di amplificazione in dotazione con il Q5, fosse paragonabile al modulo A5 della stessa Fiio
    • PlayStereo
      2018-05-16 21:27
      Il modulo di amplificazione incluso con il Q5 è il FiiO AM3A, per timbro è paragonabile, ma non possiede la stessa potenza sull\'uscita sbilanciata da 3.5mm. L\'uscita bilanciata invece è di circa mezzo watt.

        Per un upgrade quale modulo consiglia? Grazie

          2018-05-17 05:41
          Se occorre una potenza paragonabile a quella dell\'A5, c\'è il modulo AM5, con normale uscita sbilanciata su porta minijack da 3.5mm. :

    Buongiorno, è compatibile con Android via usb e bluetooth ? nello specifico con Samsung S8. Grazie

      Tramite il cavo FiiO CL06 funzionerà senza problemi.

      La FiiO non pubblicizza la compatibilità con Android per via delle centinaia di varianti hardware/software, ma al 99% funziona perfettamente senza nessun problema. Se il Samsung S8 possiede un connettore usb Type C occorrerà un adattatore typeC/microUSB. Anche con Bluetooth.
