FAQ:
Q: Is there a USB charger for the FiiO E17K?
A: The FiiO E17K is a portable headphone amplifier and digital to analog converter (DAC). The E17K has a built in rechargeable lithium battery and USB charger, allowing you to charge on your PC or with a USB adapter. The E17K has fewer buttons on the front than that of its predecessor the E17.
Q: Is the FiiO E17K Alpen 2 a good AMP?
A: Of the three portable DAC Amps in my arsenal, the Fiio E17k Alpen 2 is the ONLY one that allows for this. And make no mistake about it; aside from great sound, this feature sets this unit in a league of its own. Another great feature of this unit is the super long battery life.
Q: What kind of DAC does a FiiO E17K use?
A: Out went the Tenor TE7022 USB receiver and WM8740 DAC chip and in came the SA9027 USB Receiver, together with the PCM5102, OPA1662 as low pass filter and OPA1642+LmH6643 for the Line Out. The upgraded E10K uses the same Tenor receiver and PCM5102 DAC chip. Over USB that means the E17K can handle 96kHz/32bit and 192/24 over Coax (PCM).
Q: Which is better the FiiO E17K or the Q1?
A: The flat body of the e17k is much easier to stack than the flask-like Q1 and it is similarly well finished if not better. The front and rear faces have the typical Fiio dark brushed aluminium that feels very solid and scratch resistant, flexing only under excessive force.
