FiiO E10K Olympus 2 Headphone Amp/DAC

The all-new Fiio E10K Olympus 2 headphone amp and USB DAC combo unit is quite the little beast!  Based off the previous Fiio E10 topology, the freshly updated 'Olympus 2' version adds an improved DAC (Digital to Analog Converter) and more robust headphone amplifier circuitry. The new DAC chip is the very solid PCM5102 which provides excellent linearity in the digital filter and reduces overall delay times in the audio presentation.

The E-10K Olympus 2 headphone amp stage is now being driven by the potent LMH6643 chipset that provides significantly more power and better transient response than previous iterations.  Another nice bonus is the lowered noise floor from the improved low-pass bass boost filter switch found on the FiiO E10-K. 

The Fiio E10K Olympus 2 unit can be powered only via USB through a Micro-USB port, so no need for a clunky power supply or batteries to recharge.  This unit can also be used as a 'stand alone' DAC with it's built-in line output, as a dedicated USB headphone amp and also as a USB to Coaxial converter device. With all this superb versatility at a very affordable price point, there is little to not love about the E10K Olympus 2 in our humble review opinion!
